BEHIND THE SCENES WITH RIZWAAN ABBAS

Rizwaan Abbas, Palaeoanthropologist
Meet Rizwaan Abbas—palaeoanthropologist and archaeologist working with the Semiahmoo First Nation. 

He is all kinds of awesome. I had the great pleasure of learning more about his work and research this past week on the set of BC's Fossil Bounty.

I have shared some of the Behind the Scenes moments with you including Riz holding a rather fetching mosasaur.

Rizwaan ensures that First Nation issues are addressed within multiple levels of government and that the people of the Semiahmoo First Nation always have a seat at the table. 

Semiahmoo First Nation (/ˌsɛmiˈɑːmuː/ SEM-ee-AH-moo) is the band government of the Semiahmoo people, a Coast Salish subgroup who inhabited an extensive territory across Washington state, the Strait of Georgia (now known as the Salish Sea) and the Lower Mainland of British Columbia for thousands of years.

The band's main community and offices are located on the 312 acres (1.3 km2) Semiahmoo Indian Reserve which is sandwiched between the boundary of White Rock, British Columbia and the Canada–United States boundary and Peace Arch Provincial Park.

Before 1850, they primarily spent their winters at Drayton Harbour, Birch Bay, Crescent Beach and Semiahmoo Bay. Summers were spent a few kilometres west across the shallow waters of Boundary Bay in what is now known as Tsawwassen—derived from the Halkomelem word sc̓əwaθən, meaning "land facing the sea"— and Point Roberts.

Rizwaan Abbas and Eva Svobodova on set
Point Roberts is a pene-exclave of Washington on the southernmost tip of the Tsawwassen peninsula, south of Vancouver, Canada. Point Roberts was created when the United Kingdom and the United States settled the Pacific Northwest American-Canadian border dispute in the mid-19th century with the Oregon Treaty. 

The two parties agreed that the 49th parallel would define the boundary between their respective territories, and the small area that incorporates Point Roberts is south of the 49th parallel. 

Questions about ceding the territory to the United Kingdom and later to Canada have been raised since its creation but its status has remained unchanged. Returning the land to its original Coast Salish inhabitants has not been an active topic of discussion. 

The Coast Salish are ethnically and linguistically related Indigenous peoples of the Pacific Northwest Coast, living in the Canadian province of British Columbia and the U.S. states of Washington and Oregon.

The area around the southern Tsawwassen Peninsula was a favoured fishing spot for several Coast Salish groups, who named the peninsula "q̓ʷulƛ̕əl̕". 

The first Europeans to see Point Roberts were members of the 1791 expedition of Francisco de Eliza. The maps produced from Eliza's explorations depicted Point Roberts as "Isla de Cepeda" or "Isla de Zepeda."

In 1792, the British expedition of George Vancouver and the Spanish expedition of Dionisio Alcalá Galiano encountered one another near Point Roberts. 

Hair & Makeup Artist Eva Svobodova preps Rizwaan for camera
On the morning of June 13, 1792, the two ships under Galiano sailed into Boundary Bay and verified Point Roberts was not an island, which was thus renamed Punta Cepeda. 

They then sailed around Point Roberts and immediately encountered HMS Chatham, the second ship of Vancouver's expedition. The two parties made contact and agreed to share information and work together in mapping the Strait of Georgia.

Point Roberts acquired its present name from Captain Vancouver, who named it after his friend Henry Roberts, who had originally been given command of the expedition.

In 1790, Europeans estimated the Semiahmoo population at 300. By 1854, the band's numbers were reduced to 250 from smallpox and warfare. Contact with Turtle Island’s residents proved devastating. By 1909, when the Canadian Pacific Railway's Spiral Tunnels are opened in British Columbia's Kicking Horse Pass, there were 38 band members in British Columbia. 

In 1963, that number dropped to 28 and then just 25 by 1971. Today, there are 98 registered members and 53 members who live on-site. It is a time of resurgence for the nation and Rizwaan’s working to support that endeavour.

Rizwaan Abbas on the set of BC's Fossil Bounty
Rizwaan is of Indo-Fijian descent, a descendant of Girmitiyas, and a First Generation Canadian. His heritage fuels his passion for researching, preserving and perpetuating the Indo-Fijian Culture (in Canada) for the benefit of future generations. 

Indo-Fijians are Fijian citizens of Indian descent, including people who trace their ancestry to various regions of the Indian subcontinent. Although they hailed from various regions in the Indian subcontinent, the vast majority of Indo-Fijians trace their origins to the Awadh and Bhojpur regions of the Hindi Belt in northern India.

Many of the Muslim Indo-Fijians also came from Sindh and Balochistan and various other parts of South Asia. Fiji's British colonial rulers brought Indian people to the Colony of Fiji as indentured labourers between 1879 and 1916 to work on Fiji's sugar-cane plantations. 

The Indo-Fijian community has a complex history and heritage. Coming to the Fiji Islands as indentured labourers from India between 1879 and 1920, these Girmitiyas were forced to reevaluate their place in the world while simultaneously rebuilding their culture and maintaining their traditional and religious practices in a harsh colonial environment. 

Finding no place in India, Girmitiyas created a unique Indo-Fijian culture in the Tropical South Pacific through their shared struggle for respect and acceptance. Some stayed in Fiji and others pushed further afield and found their way to our shores.

Nestled within British Columbia’s population, lies a unique Indo-Fijian culture born from the tropical paradise of the Fiji Islands. Explore the shared history of these Voyager People who left India in search of a future but found hardship in Fiji before finally finding a home.

Piltdown Skull being examined
Rizwaan's family share that lived history. He grew up in British Columbia hearing those stories firsthand. 

It is because of that sharing of lived history that he chose to study archaeology at Simon Fraser University. Archaeology is the study of how people lived in the past—all people, no matter when in the past or where in the world.

Wanting to delve deeper into both archaeology and palaeoanthropology, he continued his studies, this time in Europe. Rizwaan undertook his Masters in Paleoanthropology and Paleolithic Archaeology at the prestigious University College London where he graduated with distinction. 

The UCL Institute of Archaeology and Department of Anthropology have considerable staff expertise in the fields of palaeoanthropology and palaeolithic archaeology. Staff and research students are currently involved in field projects as well as museum-based studies in Britain, various parts of Europe, the Middle East, and eastern and southern Africa.

His research focus was on the Geometric and Morphometrics Analysis of Molars. His work led to a remarkable discovery which he published in the Royal Society Open Science in 2016, “New genetic and morphological evidence suggests a single hoaxer created Piltdown man.“’

In 1912, palaeontologist Arthur Smith Woodward and amateur antiquarian and solicitor Charles Dawson announced the discovery of a fossil that supposedly provided a link between apes and humans: Eoanthropus dawsoni meaning Dawson's Dawn Man. 

Museum of Surrey - The Indo-Fijians: Surrey's Pocket of Paradise

The publication generated huge interest from scientists and the general public. Piltdown man's initial celebrity has long been overshadowed by its subsequent infamy as one of the most famous scientific frauds in history. 

His re-evaluation of the Piltdown fossils using the latest scientific methods (DNA analyses, high-precision measurements, spectroscopy and virtual anthropology) shows that it is highly likely that a single orang-utan specimen and at least two human specimens were used to create the fake fossils.

The modus operandi was found consistent throughout the assemblage (specimens are stained brown, loaded with gravel fragments and restored using filling materials), linking all specimens from the Piltdown I and Piltdown II sites to a single forger—Charles Dawson.

Whether Dawson acted alone is uncertain, but his hunger for acclaim may have driven him to risk his reputation and misdirect the course of anthropology for decades. The Piltdown hoax stands as a cautionary tale to scientists not to be led by preconceived ideas but to use scientific integrity and rigour in the face of novel discoveries.

BC'S FOSSIL BOUNTY: BEHIND THE SCENES WITH JOHN FAM

Meet John Fam, Vice Chair of the Vancouver Paleontological Society. 

The awesome folk in the Vancouver Paleontological Society and Vancouver Island Palaeontological Society have been collecting with John for many years, some exciting local trips — and some epic trips of a lifetime. 

Visiting the fossil outcrops at Tyaughton in the Taseko Lakes area of British Columbia takes months of planning. Remote, dangerous and difficult to reach, these sites are epic and each of those field trips definitely count as trips of a lifetime.

John shares Tales of Tyaughton in his episode of BC's Fossil Bounty.

"For the longest time, a handful of BCPA members have known about the wonderful Triassic-Jurassic fossils of the Tyaughton Creek area. Some of us had been even fortunate to see the spectacular collection of Jurassic ammonites stored in the basement of the Geological Survey of Canada.

I still remember purchasing a copy of Hettangian Ammonoid Faunas of the Taseko Lakes Area by Hans Frebold and wondering if I would even get a chance to visit such a remote locality. If you picture a squid living inside a sea shell floating and hunting in the ocean, these were the ancient creatures we’d be looking for.

As Karen Lund, one of the Directors of the Vancouver Paleontological Society (VanPS), told me, "Tyaughton is kind of like the Eldorado for the VanPS.”

We had heard so many stories that this site was becoming somewhat legendary in our minds. Thus, I made it a personal goal of mine to visit the remote fossil beds.

I began researching all possible sources related to Tyaughton Creek. I dug up many old GSC reports by Hans Frebold, Howard Tipper and George Jeletzky along with more recent material by Paul-Smith and his grad students.

All this literature was very helpful in understanding not only the fossil localities but also the complex geology of the region. I also paid a couple of visits to Dr. Howard Tipper of Geological Survey of Canada. 

Dr. Tipper was very supportive and helpful in providing valuable information regarding the fossil sites. He also shared with me his extensive knowledge of Jurassic palaeontology.

Armed with this information, I met up with Heidi Henderson, then Chair of the Vancouver Palaeontological Society, who you’ll know as the Fossil Huntress, to plan the first of four expeditions.

We had to figure out how to access such a rugged and remote locality. The fossil beds are 16 km from the nearest logging road, several hundred kilometres from Vancouver and 7,500 feet above sea level.

We would be sharing territory with a healthy Grizzly bear population and likely be a food source for the not as large but equally daunting horsefly population. 

We were keen to access this elusive site, but hiking in 16 km and gaining about a thousand feet or more of elevation would be a challenge. Hiking back out with 50 kg of rock would be impossible. 

We finally decided that it would be best that we fly in by helicopter. That, too, provided its own challenges. In the end, we did four trips over many field seasons. 

We met many Grizzly bears, horseflies, we were snowed in but came away with many wonderful fossils including new species. The undergrad we brought on the first trip did her PhD over that time and now teaches at the University of British Columbia."

Here's John Fam Behind the Scene prepping for that episode and Eva Svobodova doing her magic with Hair and Makeup on the set at Shoreline Studios in Vancouver.

BC'S FOSSIL BOUNTY: BEHIND THE SCENES

Eugene, Gavin, Julius & Eva BTS on BC's Fossil Bounty — Season Two
We have started filming Season Two of BC's Fossil Bounty. Here is a sneak peek of Eva Svobodova doing her last bit of hair & makeup magic to prep Dr. Julius Csotonyi for his interview for BC's Fossil Bounty.

What you are seeing here is Studio One at Shoreline Studios in Vancouver with some of the cast and crew. 

To the left are the profiles of Gavin Hamilton, Production and Camera Assistant along with Eugene Ko, our awesome Location Sound Mixer for both Season One and Two. 

We had three cameras in place to capture the best of Julius and the glorious painting he brought to life. Just to the right outside of this photograph, we have D'Arcy Hamilton, Cinematographer and Andrew de Villiers, Director from Film Vancouver Productions. 

We did a deep dive in Season One of the career of Dr. Julius Csotonyi, a Vancouver-based scientific illustrator and natural history fine artist. We wanted to have him back (you asked and we answered) to share a particular story of how he fills the walls of museums with murals and what goes into that process. 

Julius has a scientific background in ecology (MSc) and microbiology (PhD) which has taken him to study sensitive ecosystems, from sand dunes in the Rocky Mountain parks to hydrothermal vents at the bottom of the Pacific Ocean.

Eugene Ko, Location Sound Mixer, BC's Fossil Bounty
These experiences have fuelled his strong resolve to work toward preserving our Earth’s biota. Painting biological subjects is one means that he uses to both enhance public awareness of biological diversity and to motivate concern for its welfare. 

For Season Two, along with the tale of how the Smithsonian's Deep Time Exhibit unfolded, we also show you how he creates art — live!

We chose a particular arthropod that is long extinct. You'll learn which palaeo creature he chose and see it come to life when his episode airs in 2023. 

To see his episode in Season One, you can watch it on TELUS Optik TV or visit the STORYHIVE YouTube link here: https://www.youtube.com/channel/UCUerL9urNX8fHb6nHc_vrBQ

Thank you to all the awesome possums who made this production possible — cast, crew and sponsors. You truly delivered something amazing in Season One and we are tracking to do the same in Season Two. Funding is supported by TELUS STORYHIVE, DINO LAB INC. & DINOSTY FOSSILS.

DINOSAUR DUO: MARK TURNER AND JACKIE BATES

Mark Turner & Jackie Bates, Associate Producers, BC's Fossil Bounty
Back in 2000, when he was just 11 years old, Mark Turner was tubing down a river in northern British Columbia near Tumbler Ridge and literally fell onto a Dinosaur Trackway. 

The rapids he and his friend Daniel Helm, then 8, were playing in had tossed them into the water. 

When they reached the shore, they looked down to see dinosaur tracks. 

Finding evidence of dinosaurs is the dream for many, kids and adults included. 

While the boys knew what they saw, the adults were not convinced. Daniel had the clever idea to rub baby powder into the dips, nooks and crannies to reveal wide, rounded footprints. 

They were diagnostic and clearly showed dinosaur footprints about 95 to 97 million years old — they showed the clear impression of marks from a four-toed back foot and front feet shaped like crescents, with five bumps for toes — strolling along the creek. 

Mark Turner, DINOSTY, Associate Producer, BC's Fossil Bounty

That discovery launched a community brought to life through palaeontology in Tumbler Ridge and rocked the world with new discoveries.

It is an exciting tale and you will hear it directly from the source as Mark Dale Turner, DINOSTY joins us for Season Two of BC's Fossil Bounty. He is a natural in front of the lens and tells a great tale! 

Mark was an Associate Producer and his talented fiance Jacklynn (Jackie) Joyce Bates was our Locations Manager and Production Assistant for BC's Fossil Bounty — Season One. 

We were thrilled to have this dynamic duo on set with us this week. We welcome them both back as Associate Producers for Season Two.

We are excited to have them both in front of and behind the lens for the show to talk fossils, dinosaur finds and more about their lives together hunting Red Blazers — ammolite ammonites! 

You will love this episode. Look for it SUMMER 2023 on TELUS Optik TV and on the STORYHIVE and ARCHEA YouTube Channels! Funding supported by TELUS STORYHIVE, DINO LAB INC. and DINOSTY.

ANCIENT OCTOPUS: KEUPPIA

A sweet as you please example of Keuppia levante (Fuchs, Bracchi & Weis, 2009), an extinct genus of octopus that swam our ancient seas back in the Cretaceous. 

The dark black and brown area you see here is his ink sac which has been preserved for a remarkable 95 million years.

This cutie is in the family Palaeoctopodidae, and one of the earliest representatives of the order Octopoda — and perhaps my favourite fossil. It was this perfect specimen that inspired the logo for the Fossil Huntress brand.  

These ancient marine beauties are in the class Cephalopoda making them relatives of our modern octopus, squid and cuttlefish.

There are two species of Keuppia, Keuppia hyperbolaris and Keuppia levante, both of which we find as fossils. We find their remains, along with those of the genus Styletoctopus, in Cretaceous-age Hâqel and Hjoula localities in Lebanon. 

For many years, Palaeoctopus newboldi (Woodward, 1896) from the Santonian limestones at Sâhel Aalma, Lebanon, was the only known pre‐Cenozoic coleoid cephalopod believed to have an unambiguous stem‐lineage representative of Octobrachia fioroni

With the unearthing of some extraordinary specimens with exquisite soft‐part preservation in the Lebanon limestones, our understanding of ancient octopus morphology has blossomed. The specimens are from the sub‐lithographical limestones of Hâqel and Hâdjoula, in northwestern Lebanon. These localities are about 15 km apart, 45 km away from Beirut and 15 km away from the coastal city of Jbail. Fuchs et al. put a nice little map in their 2009 paper that I've included and referenced here.

Palaeoctopus newboldi had a spherical mantle sac, a head‐mantle fusion, eight equal arms armed with suckers, an ink sac, a medially isolated shell vestige, and a pair of (sub‐) terminal fins. The bipartite shell vestige suggests that Palaeoctopus belongs to the octopod stem‐lineage, as the sister taxon of the Octopoda, the Cirroctopoda, is characterized by an unpaired clasp‐like shell vestige (Engeser 1988; Haas 2002; Bizikov 2004).

It is from the comparisons of Canadian fauna combined with those from Lebanon and Japan that things really started to get interesting with Octobrachia. Working with fossil specimens from the Campanian of Canada, Fuchs et al. (2007a ) published on the first record of an unpaired, saddle‐shaped shell vestige that might have belonged to a cirroctopod. 

Again from the Santonian–Campanian of Canada and Japan, Tanabe et al. (2008) reported on at least four different jaw morphotypes. Two of them — Paleocirroteuthis haggarti (Tanabe et al., 2008) and Paleocirroteuthis Pacifica  (Tanabe et al ., 2008) — have been interpreted as being of cirroctopod type, one of octopod type, and one of uncertain octobrachiate type. 

Interestingly Fuchs et al. have gone on to describe the second species of Palaeoctopus, the Turonian Palaeoctopus pelagicus from limestones at Vallecillo, Mexico. While more of this fauna will likely be recovered in time, their work is based solely on a medially isolated shell vestige.

Five new specimens have been found in the well-known Upper Cenomanian limestones at Hâqel and Hâdjoula in Lebanon that can be reliably placed within the Octopoda. Fuchs et al. described these exceptionally well‐preserved specimens and discuss their morphology in the context of phylogeny and evolution in their 2008 paper (2009 publishing) in the Palaeontology Association Journal, Volume 51, Issue 1.

The presence of a gladius vestige in this genus shows a transition from squid to octopus in which the inner shell has divided into two parts in early forms to eventually be reduced to lateralized stylets, as can be seen in Styletoctopus.

The adorable fellow you see here with his remarkable soft-bodied preservation and inks sack and beak clearly visible is Keuppia levante. He hails from Late Cretaceous (Upper Cenomanian) limestone deposits near Hâdjoula, northwestern Lebanon. The vampyropod coleoid, Glyphiteuthis abisaadiorum n. sp. is also found at this locality. This specimen is about 5 cm long.

UNESCOCERATOPS KOPPELHUSAE BY JULIUS CSOTONYI

Unescoceratops koppelhusae, Julius Csotonyi
A very sweet small leptoceratopsid dinosaur, Unescoceratops koppelhusae — a new species in the collections of the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta.

The colourful and beautifully detailed painting you see here is by the very talented Julius Csotonyi who captured the magnificence of form, texture and palette to bring this small leptoceratopsid dinosaur to life.

The Royal Tyrrell Museum of Palaeontology, named in honour of Joseph Burr Tyrrell, is a palaeontology museum and research facility in Drumheller, Alberta, Canada. 

This jaw is the holotype specimen of this small leptoceratopsid dinosaur. Only a handful of isolated fossils have been found from this species, including a jaw that is the holotype specimen now in collections at the Royal Tyrell. 

The Royal Tyrrell Museum of Palaeontology, named in honour of Joseph Burr Tyrrell, is a palaeontology museum and research facility in Drumheller, Alberta, Canada. 

Unescoceratops koppelhusae, RTMP Collections
The rusty chocolate jaw bone you see here is the puzzle piece that helped all of the research come together and help us to better understand more about the diminutive leptoceratopsid dinosaurs from Alberta. 

The Cleveland Museum of Natural History's Michael Ryan and David Evans of the Royal Ontario Museum in Toronto recently determined that the specimen was a new genus and species. 

Unescoceratops is a genus of leptoceratopsid ceratopsian dinosaurs known from the Late Cretaceous (about 76.5-75 million years ago) of Alberta, Canada. Unescoceratops is thought to have been between one and two meters long and less than 91 kilograms. A plant-eater, its teeth were the roundest of all Leptocertopsids.

Dinosaur Provincial Park, Alberta, Canada
The genus name acknowledges the UNESCO  World Heritage Site, Dinosaur Provincial Park, where the fossil was found. 

In addition to its particularly beautiful scenery, Dinosaur Provincial Park – located at the heart of the province of Alberta's badlands – is unmatched in terms of the number and variety of high-quality specimens.

To date, they represent more than 44 species, 34 genera and 10 families of dinosaurs, dating back 75-77 million years. This provides us with remarkable insight into life millions of years ago.

The park contains exceptional riparian habitat features as well as badlands of outstanding aesthetic value.

The creamy honey, beige and rust coloured hills around the fossil locality are outstanding examples of major geological processes and fluvial erosion patterns in semi-arid steppes — think glorious! 

The scenic badlands stretch along 26 kilometres of high quality and virtually undisturbed riparian habitat, presenting a landscape of stark but exceptional natural beauty.

The species name honours Dr. Eva Koppelhus, who has made significant contributions to vertebrate palaeontology and palynology. 

The genus is named to honour the UNESCO World Heritage Site designation for the locality where the specimen was found and from the Greek “ceratops,” which means 'horned face'. 

Dr Michael Ryan explained that he meant to honour UNESCO's efforts to increase understanding of natural history sites around the world.

YORKSHIRE HISTORY: TEXTILES, FOSSILS AND URINE

Yorkshire Coast
You may recall the eight-metre Type Specimen of the ichthyosaur, Temnodontosaurus crassimanus, found in an alum quarry in Yorkshire, northern England.

The Yorkshire Museum was given this important ichthyosaur fossil back in 1857 when alum production was still a necessary staple of the textile industry. Without that industry, many wonderful specimens would likely never have been unearthed.

These quarries are an interesting bit of British history as they helped shape the Yorkshire Coast, created an entirely new industry and gave us more than a fixative for dyes. With them came the discovery of many remarkable fossil specimens and, oddly, local employment in the collection of urine.

In the 16th century, alum was essential in the textile industry as a fixative for dyes. 

By the first half of the 16th century, the clothing of the Low Countries, German states, and Scandinavia had developed in a different direction than that of England, France, and Italy, although all absorbed the sobering and formal influence of Spanish dress after the mid-1520s. Those fashions held true until the Inquisition when religious persecution, politics and fashion underwent a much-needed overhaul to something lighter.

Fashion in Medieval Livonia (1521): Albrecht Dürer
Elaborate slashing was popular, especially in Germany. In the depiction you see here, an artist pokes a bit of fun at Germanic fashion from the time. Bobbin lace arose from passementerie in the mid-16th century in Flanders, the Flemish Dutch-speaking northern portion of Belgium. Black was increasingly worn for the most formal occasions.

This century saw the rise of the ruff, which grew from a mere ruffle at the neckline to immense, slightly silly, cartwheel shapes. They adorned the necklines of the ultra-wealthy and uber-stylish men and women of the age.

At their most extravagant, ruffs required wire supports and were made of fine Italian reticella, a cutwork linen lace. You can imagine the many hours of skill and patience that would have gone into each piece to create the artful framework of these showy lace collars.

16th Century Fashion / Ruff Collars and Finery
In contrast to all that ruff, lace and cutwork linen, folk needed dyed fabrics. And to fix those dyes, they needed Alum. For a time, Italy was the source of that alum.

The Pope held a tidy monopoly on the industry, supplying both alum and the best dyes. He also did a nice trade in colourful and rare pigments for painting. And for a time, all was well with dandy's strutting their finery to the local fops in Britain.

All that changed during the Reformation. Great Britain, heathens as they were, were cut off from their Papal source and needed to fend for themselves.

The good Thomas Challoner took up the charge and set up Britain's first Alum works in Guisborough. Challoner looked to palaeontology for inspiration. Noticing that the fossils found on the Yorkshire coast were very similar to those found in the Alum quarries in Europe, he hatched a plan to set-up an alum industry on home soil. 

As the industry grew, sites along the coast were favoured as access to the shales and subsequent transportation was much easier.

Alum House, Photo: Joyce Dobson and Keith Bowers
Alum was extracted from quarried shales through a large scale and complicated process which took months to complete. 

The process involved extracting then burning huge piles of shale for 9 months, before transferring it to leaching pits to extract an aluminium sulphate liquor. This was sent along channels to the alum works where human urine was added.

At the peak of alum production, the industry required 200 tonnes of urine every year. That's the equivalent of all the potty visits of more than 1,000 people. Yes, strange but true.

The steady demand was hard to keep up with and urine became an imported resource from markets as far away as London and Newcastle upon Tyne in the northeast of England. Wooden buckets were left on street corners for folk to do their business then carted back to the south to complete the alum extraction process. The urine and alum would be mixed into a thick liquid. Once mixed, the aromatic slosh was left to settle and then the alum crystals were removed.

I'm not sure if this is a folktale or plain truth, but as the story goes, one knows when the optimum amount of alum had been extracted as you can pop an egg in the bucket and it floats on its own.

Alum House. Photo: Ann Wedgewood and Keith Bowers
The last Alum works on the Yorkshire Coast closed in 1871. This was due to the invention of manufacturing synthetic alum in 1855, then subsequently the creation of aniline dyes that contained their own fixative.

Many sites along the Yorkshire Coast bear evidence of the alum industry. These include Loftus Alum Quarries where the cliff profile is drastically changed by extraction and huge shale tips remain.

Further South are the Ravenscar Alum Works, which are well-preserved and enable visitors to visualize the processes which took place. The photos you see here are of Alum House at Hummersea. The first shows the ruin of Alum House printed on a postcard from 1906. The second (bottom) image shows the same ruin from on high with Cattersty Point in the background.

The good folk at the National Trust in Swindon are to thank for much of the background shared here. If you'd like to learn more about the Yorkshire area or donate to a very worthy charity, follow their link below.

TEMNODONTOSAURUS CRASSIMANUS

Temnodontosaurus crassimanus
This big beastie is the ichthyosaur, Temnodontosaurus crassimanus, who graced our ancient oceans 180 million years ago. The species was originally named by Richard Owen, the first superintendent of the Natural History Museum. Owen lived at the height of the gentleman scientist and it was Owen who first coined the name dinosaur. Dean Lomax did some work with this specimen as part of his research leading up to his PhD.

The fellow you see here is the Type Specimen for the species and he lives on display in the Yorkshire Museum. As the reference specimen for the species, all hopeful specimens that may belong to this species are checked against the Type Specimen to see if they share diagnostic features.

The Yorkshire Museum was given this important ichthyosaur fossil back in 1857, albeit in bits and pieces. The first bits of fossil bones were found near Whitby on the North Yorkshire coast by workmen quarrying alum. They recognized the bones as belonging to a fossilized reptile and alerted local authorities who in turn alerted the good Master Owen.

It was quite an undertaking to recover as it was found in more than fifty pieces in massive shale blocks and the alum quarry was active at the time. Alum quarrying helped share the Yorkshire Coast as an important staple of the textile industry going back to the 16th-century. By the 1860s, alum quarrying was slowing down. The ability to manufacture synthetic alum by 1855 had shifted the industry and it died out entirely by 1871. Lucky for us, the last years of alum production gifted us this well-preserved eight-metre specimen, one of the largest ichthyosaurs ever discovered in the UK.

NATURAL DYES: INDIGO

Natural dyes are dyes or colourants derived from plants, invertebrates, or minerals. The majority of natural dyes are vegetable dyes from plant sources — roots, berries, bark, leaves, and wood — and other biological sources such as fungi and lichens.

Archaeologists have found evidence of textile dyeing dating back to the Neolithic period. In China, dyeing with plants, barks and insects has been traced back more than 5,000 years and looks to be our first attempt at the practice of chemistry.

The essential process of dyeing changed little over time. Typically, the dye material is put in a pot of water and then the textiles to be dyed are added to the pot, which is heated and stirred until the colour is transferred. Sometimes, we use workers with stout marching legs to mix this up.

Traditional dye works still operate in many parts of the world. There is a revival of using natural indigo in modern Egypt — although their indigo dye is mostly imported. The same is true further south in Sudan. They've been importing cloth from Upper Egypt as far back as we have written records and continue the practice of the cloth and dye imports today. Clean white cotton is more the style of western Sudan and Chad, but they still like to throw in a bit of colour.

Traditional Dye Vats
So do the folk living in North Africa. Years ago, I was travelling in Marrakesh and saw many men with noticeably orange, blueish or purplish legs. It wasn't one or two but dozens of men and I'd wondered why this was.

My guide took me to the top of a building so I could look down on rows and rows of coloured vats. In every other one was a man marching in place to work the dye into the wool. Their legs took on the colour from their daily march in place in huge tubs of liquid dye and sheared wool. This wool would be considered textile fibre dyed before spinning — dyed in the wool — but most textiles are yarn-dyed or piece-dyed after weaving.

Many natural dyes require the use of chemicals called mordants to bind the dye to the textile fibres; tannin from oak galls, salt, natural alum, vinegar, and ammonia from stale urine were staples of the early dyers.

Many mordants and some dyes themselves produce strong odours. Urine is a bit stinky. Not surprisingly, large-scale dyeworks were often isolated in their own districts.

Woad, Isatis tinctoria
Plant-based dyes such as Woad, Isatis tinctoria, indigo, saffron, and madder were raised commercially and were important trade goods in the economies of Asia and Europe. Across Asia and Africa, patterned fabrics were produced using resist dyeing techniques to control the absorption of colour in piece-dyed cloth.

Dyes such as cochineal and logwood, Haematoxylum campechianum, were brought to Europe by the Spanish treasure fleets, and the dyestuffs of Europe were carried by colonists to America.

Throughout history, people have dyed their textiles using common, locally available materials, but scarce dyestuffs that produced brilliant and permanent colours such as the natural invertebrate dyes. Crimson kermes became highly prized luxury items in the ancient and medieval world. Red, yellow and orange shades were fairly easy to procure as they exist as common colourants of plants. It was blue that people sought most of all and purple even more so.

Indigofera tinctoria, a member of the legume or bean family proved just the trick. This lovely plant —  named by the famous Swedish botanist Carl Linneaus, the father of formalized binomial nomenclature — grows in tropical to temperate Asia and subtropical regions, including parts of Africa.

The plants contain the glycoside indican, a molecule that contains a nitrogenous indoxyl molecule with some glucose playing piggyback. Indigo dye is a product of the reaction of indoxyl by a mild oxidizing agent, usually just good old oxygen.

To make the lovely blue and purple dyes, we harvest the plants and ferment them in vats with urine and ash. The fermentation splits off the glucose, a wee bit of oxygen mixes in with the air (with those sturdy legs helping) and we get indigotin — the happy luxury dye of royalty, emperors and kings.

While much of our early dye came from plants — now it is mostly synthesized — other critters played a role. Members of the large and varied taxonomic family of predatory sea snails, marine gastropod mollusks, commonly known as murex snails were harvested by the Phoenicians for the vivid dye known as Tyrian purple.

While the extant specimens maintained their royal lineage for quite some time; at least until we were able to manufacture synthetic dyes, it was their fossil brethren that first captured my attention. There are about 1,200 fossil species in the family Muricidae. They first appear in the fossil record during the Aptian of the Cretaceous.

Their ornate shells fossilize beautifully. I'd first read about them in Addicott's Miocene Gastropods and Biostratigraphy of the Kern River Area, California. It's a wonderful survey of 182 early and middle Miocene gastropod taxa.

SEA ANEMONE NURSERY

Sea anemones are familiar inhabitants of rocky shores and coral reefs around the world; other species can be found at very low depths indeed. Most of the soft-bodied anthozoans known as "sea anemones" are classified in the Actinaria.

Most actinarians are sessile; that is, they live attached to rocks or other substrates and do not move, or move only very slowly by contractions of the pedal disk. A number of anemones burrow into sand, and a few can even swim short distances, by bending the column back and forth or by "flapping" their tentacles. In all, there are about 1000 species of sea anemone in the world's oceans.

Sea anemones breed by liberating sperm and eggs through their mouth into the sea. The fertilized eggs develop into planula larvae which, after being planktonic for a while, settle on the seabed and develop directly into juvenile polyps. Sea anemones can also breed asexually, by breaking in half or into smaller pieces which regenerate into polyps.

They are sometimes kept in reef aquariums; the global trade in marine ornamentals is expanding and threatens sea anemone populations in some localities, as the trade depends on collection from the wild. Most Actiniaria do not form hard parts that can be recognized as fossils, but a few fossils of sea anemones do exist; Mackenzia, from the Stephen Formation, Middle Cambrian Burgess Shale of Canada, is the oldest fossil identified as a sea anemone.

Some fossil sea anemones have also been found from the Lower Cambrian of China. The new find lends support to genetic data that suggests anthozoans — anemones, corals, octocorals and their kin — were one the first Cnidarian groups to diversify.

HERMIT CRAB: XALA'IS GUGWIS

This little cutie is a hermit crab and he is wearing a temporary home borrowed from one of our mollusc friends. 

His body is a soft, squishy spiral that he eases into the perfect size shell time and time again as he grows. His first choice is always the empty shell of a marine snail but will get inventive in a pinch — nuts, wood, serpulid worm tubes, aluminium cans or wee plastic caps. 

They are inventive, polite and patient. I think of them as I hunt for elusive parking in Kitsilano and watch friends lining up for scarce apartment rentals. 

You see, a hermit crabs' desire for the perfect bit of real estate will have them queueing beside larger shells — shells too large for them — to wait upon a big hermit crab to come along, discard the perfect home and slip into their new curved abode. This is all done in an orderly fashion with the hermit crabs all lined up, biggest to smallest to see who best fits the newly available shell. 

There are over 800 species of hermit crab — decapod crustaceans of the superfamily Paguroidea. Their lineage dates back to the Jurassic, 200 million years ago. Their soft squishy, weakly calcified bodies do not fossilize all that often but when they do the specimens are spectacular. 

Think of all the species of molluscs these lovelies have had a chance to try on — including ammonites — and all the shells that were never buried in sediment to become fossils because they were harvested as homes.  

On the shores of British Columbia, the hermit crab I come across the most is the Grainyhand hermit crab, Pagurus granosimanus. These wee fellows have tell-tale orange-brown antennae and olive green legs speckled with blue or white dots. 

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, a shell is known as x̱ala̱'is and gugwis means house on the beach. I do not know the Kwak’wala word for hermit crab, so I will think of these cuties as x̱ala̱'is gugwis — envisioning them finding the perfect sized shell on the surf worn shores of Tsax̱is, Fort Rupert, Vancouver Island.

EUSTHENOPTERON FORDI: DEVONIAN FISH

An exquisite fossil specimen of an Eusthenopteron Fordi from the upper Devonian (Frasnian), Eescuminac Formation, Miguasha Park, Bay of Heat, Gaspé, Quebec, Canadian Museum of Natural History, Miguasha Collection.

If you look closely at this specimen, you can see the remarkable 3-D and soft-bodied preservation. This fish specimen reminds me of the ray-finned fossil fish you see in carbonate concretion from Lower Cretaceous deposits in the Santana Formation, Brazil.

Eusthenopteron would have shared our ancient seas with the first ammonites and primitive sharks, along with well-established fauna including the trilobites, brachiopods, coral reefs and a whole host of interesting arthropods.

Miguasha National Park / Parc National de Miguasha, is a protected area near Carleton-sur-Mer on the Gaspé Peninsula along the south side of the Saint Lawrence River to the east of the Matapedia Valley in Quebec, Canada. It was created in 1985 by the Government of Quebec and designated as a World Heritage Site in 1999 in honour of paleontological significance for Devonian fish, flower and spore fossils.

These fossils represent five of the six main fossil fish groups recorded from the Devonian (370 million years ago) including specimens of the lobe-finned fish and tetrapods. We see the placoderms, armoured prehistoric fish, in their heyday, dominating almost every known aquatic environment. The Devonian is known as the 'Age of Fishes,' but it could have equally been called the 'Age of Spores,' as this was a time of significant adaptive radiation of terrestrial biota and free-sporing vascular plants. Immense forests carpeted the continents and we see the first of the plant groups evolving leaves, true roots and seeds.

The site was discovered in 1842 by a local geologist and medical doctor, Abraham Gesner. He shared much of his collection with both the British Museum and Royal Scottish Museum for further study.  Other names for this site are the Miguasha Fossil Site, the Bay of Escuminac Fossil Site, the Upper Devonian Escuminac Formation, and the Hugh-Miller Cliffs. It is also sometimes referred to on fossil specimens as 'Scaumenac Bay' or 'Scaumenac Bay P.Q. Photo credit to the deeply awesome John Fam

THE EVOLUTION OF FISH

The evolution of fish began about 530 million years ago with the first fish lineages belonged to the Agnatha, a superclass of jawless fish. We still see them in our waters as cyclostomes but have lost the conodonts and ostracoderms to the annals of time. Like all vertebrates, fish have bilateral symmetry; when divided down the middle or central axis, each half is the same. Organisms with bilateral symmetry are generally more agile, making finding a mate, hunting or avoiding being hunted a whole lot easier.

When we envision fish, we generally picture large eyes, gills, a well-developed mouth. The earliest animals that we classify as fish appeared as soft-bodied chordates who lacked a true spine. While they were spineless, they did have notochords, a cartilaginous skeletal rod that gave them more dexterity than the cold-blooded invertebrates who shared those ancient seas and evolved without a backbone. Fish would continue to evolve throughout the Paleozoic, diversifying into a wide range of forms. Several forms of Paleozoic fish developed external armour that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many species, including sharks, became formidable marine predators rather than just the prey of arthropods.

Fishes in general respire using gills, are most often covered with bony scales and propel themselves using fins. There are two main types of fins, median fins and paired fins. The median fins include the caudal fin or tail fin, the dorsal fin, and the anal fin. Now there may be more than one dorsal, and one anal fin in some fishes.

The paired fins include the pectoral fins and the pelvic fins. And these paired fins are connected to, and supported by, pectoral and pelvic girdles, at the shoulder and hip; in the same way, our arms and legs are connected to and supported by, pectoral and pelvic girdles. This arrangement is something we inherited from the ancestors we share with fishes. They are homologous structures.

When we speak of early vertebrates, we're often talking about fishes. Fish is a term we use a lot in our everyday lives but taxonomically it is not all that useful. When we say, 'fish' we generally mean an ectothermic, aquatic vertebrate with gills and fins.

 Eohiodon Fish Fossil / McAbee
Fortunately, many of our fishy friends have ended up in the fossil record. We may see some of the soft bits from time to time, but we often see fish skeletons as in this Eohiodon fossil fish from the McAbee Fossil Beds near Cache Creek, British Columbia. 

Vertebrates with hard skeletons had a much better chance of being preserved. 

We have the Tiktaalik roseae, a large freshwater fish, from 375 million-year-old Devonian deposits on Ellesmere Island in Canada's Arctic. Tiktaalik is a wonderfully bizarre creature with a flat, almost reptilian head but also fins, scales and gills. We have other wonders from this time. There are also spectacular antiarch placoderms, Bothriolepsis, found in the Upper Devonian shales of Miguasha in Quebec.

There are fragments of bone-like tissues from as early as the Late Cambrian with the oldest fossils that are truly recognizable as fishes come from the Middle Ordovician from North America, South America and Australia. At the time, South America and Australia were part of a supercontinent called Gondwana. North America was part of another supercontinent called Laurentia and the two were separated by deep oceans.

FOSSIL AMPHIBIANS OF NOVA SCOTIA

Dendrerpeton acadianum, an extinct amphibian
One of the best Canadian fossil finds stems from a random boulder picked up on the beach near the town of Joggins, Nova Scotia. Inside were the bones of a fully articulated skeleton of Dendrerpeton acadianum, a Temnospondyli from the Lower Pennsylvanian. 

These little cuties belong to an extinct genus of amphibians who loved wet, swampy wetlands similar to those we find in the bayous of Mississippi today.   

Dendrerpeton is the primitive sister-group to a clade of Temnospondyls that includes Trimerorhachoids, the Eryopoids — Ervops, Parioxys, & Sclerocephalus — Zatracheids & Dissorophoids. 

This little guy along with finding the first true reptile, Hylonomus lyelli, ancestor of all dinosaurs that would rule the Earth 100 million years later serve as the reference point where animals finally broke free of the water to live on land. This evolutionary milestone recorded at Joggins remains pivotal to understanding the origins of all vertebrate life on land, including our own species. 

Joggins records life in a once a wet, swampy wetland
Sir Charles Lyell, the author of Principles of Geology, first noted the exceptional natural heritage value of the Joggins Fossil Cliffs. He described them as: 

“...the finest example in the world of a natural exposure in a continuous section ten miles long, occurs in the sea cliffs bordering a branch of the Bay of Fundy in Nova Scotia.” 

Indeed, the world-famous Bay of Fundy with its impressive tides, the highest in the world, and stormy nature exposed much of this outcrop.

FOSSILS FROM TURTLE ISLAND'S EASTERN COASTLINE

Hylonomus lyelli, Ancestor of all dinosaurs
The fossil cliffs at Joggins are one of Canada's gems, now a UNESCO World Heritage Site, you can visit to see our ancient world frozen in time. 

Preserved in situ is a snapshot of an entire food chain of a terrestrial Pennsylvanian Coal Age wetland.

The outcrop holds fossil plant life — including impressive standing lycopsid trees that formed the framework of these wetlands — decomposing detritivores in the invertebrates and tetrapods, the predatory carnivores of the day.

The Coal Age trees were fossilized where they stood 300-million-years ago with the remains of the earliest reptiles entombed within. The preservation is quite marvellous with the footprints of creatures who once lived in these wetlands are frozen where they once walked and the dens of amphibians are preserved with remnants of their last meal. 

Nowhere is a record of plant, invertebrate and vertebrate life within now fossilized forests rendered more evocatively. The fossil record at Joggins contains 195+ species of plants, invertebrates and vertebrates. The fossil plant life became the vast coal deposits for which this period of Earth's history is named. 

Recorded in the rock are vertebrate and invertebrate fauna both aquatic and terrestrial. This broad mix of specimens gives us a view into life back in the Pennsylvanian and sets us up to understand their ecological context.
Pennsylvanian Coal Age Ecosystem, 300-Million-Years-Old
The fossil record includes species first defined at Joggins, some of which are found nowhere else on Earth. 

It was here that Sir Charles Lyell, with Sir William Dawson, founder of modern geology, discovered tetrapods — amphibians and reptiles — entombed in the upright fossil trees. 

Later work by Dawson would reveal the first true reptile, Hylonomus lyelli, ancestor of all dinosaurs that would rule the Earth 100 million years later. 

This tiny reptile serves as the reference point where animals finally broke free of the water to live on land. This evolutionary milestone recorded at Joggins remains pivotal to understanding the origins of all vertebrate life on land, including our own species. 

Sir Charles Lyell, author of Principles of Geology, first noted the exceptional natural heritage value of the Joggins Fossil Cliffs, calling them “...the finest example in the world of a natural exposure in a continuous section ten miles long, occurs in the sea cliffs bordering a branch of the Bay of Fundy in Nova Scotia.” Indeed, the world-famous Bay of Fundy with its impressive tides, the highest in the world, and stormy nature exposed much of this outcrop. 

Geological accounts of the celebrated coastal section at Joggins first appear in the published literature in 1828–1829, by Americans C.T. Jackson and F. Alger, and by R. Brown and R. Smith, managers for the General Mining Association in the Sydney and Pictou coal fields. Brown and Smith’s account is the first to document the standing fossil trees.

Plan Your Joggins Fossil Cliffs Staycation

Joggins Fossil Cliffs is a Canadian gem — and they welcome visitors. They offer hands-on learning and discovery microscope activities in their Fossil Lab.

You can explore interpretive displays in the Joggins Fossil Centre before heading out to the beach and cliffs with an interpreter.

Their guided tours of the fossil site include an educational component that tells you about the geology, ecology, palaeontology and conservation of this very special site. 

Joggins / Chegoggin / Mi'kmaq L'nu

We know this area as Joggins today. In Mi'kmaw, the language spoken in Mi'kma'ki, the territory of the Mi'kmaq L'nu, the area bears another name, Chegoggin, place of fishing weirs.

Booking Your Class Field Trip

If you are a teacher and would like to book a class field trip, contact the Director of Operations via the contact information listed below. They will walk you through Covid safety and discuss how to make your visit educational, memorable and fun.

Know Before You Go

The Bay of Fundy has the highest tides in the world. Beach walks are scheduled according to the tides and run regardless of the weather. Good low tides but raining, the beach walk goes on. Lovely and sunny but with a high tide, the beach walk must wait. So, you will want to dress for it as they will not be cancelled in the event of rain. Should severe weather be a factor, bookings may need to be rescheduled at the discretion of the Joggins staff.

Any questions about booking your school field trip? Feel free to email:  operations@jogginsfossilcliffs.net or call: 1 (902) 251-2727 EXT 222.

GULLS ON THE FORESHORE: T'SIK'WI

A gull cries in protest at not getting his share of a meal

Gulls, or colloquially seagulls, are seabirds of the family Laridae in the suborder Lari. 

The Laridae are known from not-yet-published fossil evidence from the Early Oligocene — 30–33 million years ago. 

Three gull-like species were described by Alphonse Milne-Edwards from the early Miocene of Saint-Gérand-le-Puy, France. 

Another fossil gull from the Middle to Late Miocene of Cherry County, Nebraska, USA, has been placed in the prehistoric genus Gaviota

These fossil gulls, along with undescribed Early Oligocene fossils are all tentatively assigned to the modern genus Larus. Among those of them that have been confirmed as gulls, Milne-Edwards' "Larus" elegans and "L." totanoides from the Late Oligocene/Early Miocene of southeast France have since been separated in Laricola.

Gulls are most closely related to the terns in the family Sternidae and only distantly related to auks, skimmers and distantly to waders. 

A historical name for gulls is mews, which is cognate with the German möwe, Danish måge, Swedish mås, Dutch meeuw, Norwegian måke/måse and French mouette. We still see mews blended into the lexicon of some regional dialects.

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest and my family, gulls are known as t̕sik̕wi. Most folk refer to gulls from any number of species as seagulls. This name is a local custom and does not exist in the scientific literature for their official naming. Even so, it is highly probable that it was the name you learned for them growing up.

If you have been to a coastal area nearly everywhere on the planet, you have likely encountered gulls. They are the elegantly plumed but rather noisy bunch on any beach. You will recognize them both by their size and colouring. 

Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh shrill cries and long, yellow, curved bills. Their webbed feet are perfect for navigating the uneven landscape of the foreshore when they take most of their meals. 

Most gulls are ground-nesting carnivores that take live food or scavenge opportunistically, particularly the Larus species. Live food often includes crab, clams (which they pick up, fly high and drop to crack open), fish and small birds. Gulls have unhinging jaws which allow them to consume large prey which they do with gusto. 

Their preference is to generally live along the bountiful coastal regions where they can find food with relative ease. Some prefer to live more inland and all rarely venture far out to sea, except for the kittiwakes. 

The larger species take up to four years to attain full adult plumage, but two years is typical for small gulls. Large white-headed gulls are typically long-lived birds, with a maximum age of 49 years recorded for the herring gull.

Gulls nest in large, densely packed, noisy colonies. They lay two or three speckled eggs in nests composed of vegetation. The young are precocial, born with dark mottled down and mobile upon hatching. Gulls are resourceful, inquisitive, and intelligent, the larger species in particular, demonstrating complex methods of communication and a highly developed social structure. Many gull colonies display mobbing behaviour, attacking and harassing predators and other intruders. 

Certain species have exhibited tool-use behaviour, such as the herring gull, using pieces of bread as bait with which to catch goldfish. Many species of gulls have learned to coexist successfully with humans and have thrived in human habitats. Others rely on kleptoparasitism to get their food. Gulls have been observed preying on live whales, landing on the whale as it surfaces to peck out pieces of flesh. They are keen, clever and always hungry.
