DOLPHIN VERTEBRAE FROM THE NORTH SEA

A lovely 17 cm deep chocolate brown fossil Bottlenose Dolphin, Tursiops sp. vertebrae found in the Brown Bank area of the North Sea, one of the busiest seaways in the world. The beautiful specimen you see here is in the collections Wendy Phillips of Vancouver Island.

Bottlenose dolphins first appeared during the Miocene and swam the shallow seas of this region. 

We still find them today in warm and temperate seas worldwide though unlike narwhal, beluga and bowhead whales, Bottlenose dolphins avoid the Arctic and Antarctic Circle regions. 

Their name derives from the Latin tursio (dolphin) and truncatus for their characteristic truncated teeth. In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest — and part of my heritage — dolphin are hatsawe'. 

On the north end of Vancouver Island, we have pods of 50-100 Pacific White-Sided dolphins, cousins of the Bottlenose, who frolic and jump alongside your boat if you are out on the water. Similar to their southern cousins, Pacific White-Sided dolphins feed on salmon, herring, pilchards, anchovies, needlefish, squid, shrimp, pollock, sablefish, rock cod and other small fish — a tasty menu that reflects my own. 

Bottlenose dolphins are the most common dolphin species in the Pacific Northwest but do not often venture farther north than Oregon. We have two populations of bottlenose dolphins here, the California coastal population and those that prefer to live offshore. It is as exciting to see them playing in our oceans today as it is to see the fossil remains of their ancestors from the Brown Bank sediments of the North Sea. 

Brown Bank, North Sea, Pleistocene Dredging Area

There are two known fossil species from Italy that include Tursiops osennae (late Miocene to early Pliocene) from the Piacenzian coastal mudstone, and Tursiops miocaenus (Miocene) from the Burdigalian marine sandstone.

Many waterworn vertebrae from the Harbour Porpoise Phocoena sp., (Cuvier, 1816), Bottlenose dolphin Tursiops sp. (Gervais, 1855), and Beluga Whale, Delphinapterus sp. (Lacépède‎, 1804‎) are found by fishermen as they dredge the bottom of the Brown Bank, one of the deepest sections of the North Sea.  

The North Sea is a sea of the Atlantic Ocean located between the United Kingdom, Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north.

The fishermen use small mesh trawl nets that tend to scoop up harder bits from the bottom. This technique is one of the only ways this Pleistocene and other more recent material is recovered from the seabed, making them relatively uncommon. The most profitable region for fossil mammal material is in the Brown Bank area of the North Sea. I have circled this area on the map below to give you an idea of the region.

These specimens are often found by fishermen in the North Sea. Using a small mesh trawl net is often the only time these come up from the seabed, hence they are uncommon. ​Size: 17.0cm. Age: 30-40,000 Years old. 

FRACTAL BUILDING: AMMONITES

Argonauticeras besairei, Collection of José Juárez Ruiz.

An exceptional example of fractal building of an ammonite septum, in this clytoceratid Argonauticeras besairei from the awesome José Juárez Ruiz.

Ammonites were predatory, squid-like creatures that lived inside coil-shaped shells.

Like other cephalopods, ammonites had sharp, beak-like jaws inside a ring of squid-like tentacles that extended from their shells. They used these tentacles to snare prey, — plankton, vegetation, fish and crustaceans — similar to the way a squid or octopus hunt today.

Catching a fish with your hands is no easy feat, as I'm sure you know. But the Ammonites were skilled and successful hunters. They caught their prey while swimming and floating in the water column. Within their shells, they had a number of chambers, called septa, filled with gas or fluid that were interconnected by a wee air tube. By pushing air in or out, they were able to control their buoyancy in the water column.

They lived in the last chamber of their shells, continuously building new shell material as they grew. As each new chamber was added, the squid-like body of the ammonite would move down to occupy the final outside chamber.

They were a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids — octopuses, squid, and cuttlefish) than they are to shelled nautiloids such as the living Nautilus species.

The Ammonoidea can be divided into six orders:

• Agoniatitida, Lower Devonian - Middle Devonian
• Clymeniida, Upper Devonian
• Goniatitida, Middle Devonian - Upper Permian
• Prolecanitida, Upper Devonian - Upper Triassic
• Ceratitida, Upper Permian - Upper Triassic
• Ammonitida, Lower Jurassic - Upper Cretaceous

Ammonites have intricate and complex patterns on their shells called sutures. The suture patterns differ across species and tell us what time period the ammonite is from. If they are geometric with numerous undivided lobes and saddles and eight lobes around the conch, we refer to their pattern as goniatitic, a characteristic of Paleozoic ammonites.

If they are ceratitic with lobes that have subdivided tips; giving them a saw-toothed appearance and rounded undivided saddles, they are likely Triassic. For some lovely Triassic ammonites, take a look at the specimens that come out of Hallstatt, Austria and from the outcrops in the Humboldt Mountains of Nevada.

Hoplites bennettiana (Sowby, 1826).

If they have lobes and saddles that are fluted, with rounded subdivisions instead of saw-toothed, they are likely Jurassic or Cretaceous. If you'd like to see a particularly beautiful Lower Jurassic ammonite, take a peek at Apodoceras. Wonderful ridging in that species.

One of my favourite Cretaceous ammonites is the ammonite, Hoplites bennettiana (Sowby, 1826). This beauty is from Albian deposits near Carrière de Courcelles, Villemoyenne, near la région de Troyes (Aube) Champagne in northeastern France.

At the time that this fellow was swimming in our oceans, ankylosaurs were strolling about Mongolia and stomping through the foliage in Utah, Kansas and Texas. Bony fish were swimming over what would become the strata making up Canada, the Czech Republic and Australia. Cartilaginous fish were prowling the western interior seaway of North America and a strange extinct herbivorous mammal, Eobaatar, was snuffling through Mongolia, Spain and England.

In some classifications, these are left as suborders, included in only three orders: Goniatitida, Ceratitida, and Ammonitida. Once you get to know them, ammonites in their various shapes and suturing patterns make it much easier to date an ammonite and the rock formation where is was found at a glance.

Ammonites first appeared about 240 million years ago, though they descended from straight-shelled cephalopods called bacrites that date back to the Devonian, about 415 million years ago, and the last species vanished in the Cretaceous–Paleogene extinction event.

They were prolific breeders that evolved rapidly. If you could cast a fishing line into our ancient seas, it is likely that you would hook an ammonite, not a fish. They were prolific back in the day, living (and sometimes dying) in schools in oceans around the globe. We find ammonite fossils (and plenty of them) in sedimentary rock from all over the world.

In some cases, we find rock beds where we can see evidence of a new species that evolved, lived and died out in such a short time span that we can walk through time, following the course of evolution using ammonites as a window into the past.

For this reason, they make excellent index fossils. An index fossil is a species that allows us to link a particular rock formation, layered in time with a particular species or genus found there. Generally, deeper is older, so we use the sedimentary layers rock to match up to specific geologic time periods, rather the way we use tree-rings to date trees. A handy way to compare fossils and date strata across the globe.

BOENY REGION OF MADAGASCAR

Aioloceras besairiei (Collingnon, 1949)

A stunning example of the internal suturing with calcite infill in this sliced Aioloceras besairiei (Collingnon, 1949) ammonite from the Upper Cretaceous (Lower Albian) Boeny region of Madagascar. 

This island country is 400 kilometres off the coast of East Africa in the Indian Ocean and a wonderful place to explore off the beaten track.

Madagascar has some of the most spectacular of all the fossil specimens I have ever seen. This beauty is no exception. The shell has a generally small umbilicus, arched to acute venter, and typically at some growth stage, falcoid ribs that spring in pairs from umbilical tubercles, usually disappearing on the outer whorls. I had originally had this specimen marked as a Cleoniceras besairiei, except Cleoniceras and Grycia are not present in Madagascar. 

This lovely, seen in cross-section, is now far from home and in the collection of a wonderful friend. It is an especially lovely example of the ammonite, Aioloceras besairiei, making it a beudanticeratinae. Cleoniceras and Grycia are the boreal genera. If you'd like to see (or argue) the rationale on the name, consider reading Riccardi and Medina's riveting work from back in 2002, or Collingnon from 1949.

The beauty you see here measures in at a whopping 22 cm, so quite a handful. This specimen is from the youngest or uppermost subdivision of the Lower Cretaceous. I'd originally thought this locality was older, but dating reveals it to be from the Lower Albian, so approximately 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma.

Aioloceras are found in the Cretaceous of Madagascar at geo coordinates 16.5° S, 45.9° E: paleo-coordinates 40.5° S, 29.3° E.; and in four localities in South Africa: at locality 36, near the Mzinene River at 28.0° S, 32.3° E: paleo-coordinates 48.6° S, 7.6° E. 

We find them near the Mziene River, at a second locality north of Hluhluwe where the Mzinene Formation overlies the Aptian-Albian Makatini Formation at 28.0° S, 32.3° E: paleo-coordinates 48.6° S, 7.6° E; and at Haughton Z18, on the Pongola River in the Albian III, Tegoceras mosense beds at 27.3° S, 32.2° E: paleo-coordinates 48.0° S, 7.8° E.

If you happen to be trekking to Madagascar, know that it's big. It’s 592,800 square kilometres (or  226,917 square miles), making it the fourth-largest island on the planet — bigger than Spain, Thailand, Sweden and Germany. The island has an interesting geologic history.

Although there has been a geological survey, which was active extending back well into French colonial times, in the non-French-speaking world our geological understanding of the island is still a bit of a mystery. 

Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." 

Wegener proposed that the continents ploughed through the crust of ocean basins, which would explain why the outlines of many coastlines (like South America and Africa) look like they fit together like a puzzle. Half a century after Wegener there is still no agreement as to whether in continental reconstructions Madagascar should be placed adjacent to the Tanzanian coast to the north (e.g., McElhinny and Embleton,1976), against the Mozambique-Natal coast (Flores 1970), or basically left where it is (Kent 1974, Nairn 1978).

There have been few attempts apart from McKinley’s (1960) comparison of the Karoo succession of southwestern Tanzania with that of Madagascar to follow the famous geological precept of “going to sea.” One critical reason is that although there may be a bibliography of several thousand items dealing with Madagascan geology as Besairie (1971) claims, they are items not generally available to the general public. The vital information gained of the geology of the offshore area by post-World War II petroleum exploration has remained largely proprietary. 

Without this data to draw upon, our understanding remains incomplete. I don't actually mind a bit of a mystery here. It is interesting to speculate on how these geologic puzzle pieces fit together and wait for the big reveal. Still, we have good old Besairie from his 1971, Geologie de Madagascar, and a later précis (Besairie, 1973).

We do know that Madagascar was carved off from the African-South American landmass early on. The prehistoric breakup of the supercontinent Gondwana separated the Madagascar–Antarctica–India landmass from the Africa–South America landmass around 135 million years ago. Madagascar later split from India about 88 million years ago, during the Late Cretaceous, so the native plants and animals on the island evolved in relative isolation. 

It is a green and lush island country with more than its fair share of excellent fossil exposures. Along the length of the eastern coast runs a narrow and steep escarpment containing much of the island's remaining tropical lowland forest. If you could look beneath this lush canopy, you'd see rocks of the Precambrian age stretching from the east coast all the way to the centre of the island. The western edge is made up of sedimentary rock from the Carboniferous to the Quaternary.

Red-Tailed Lemurs, Waiwai & Hedgehog

Madagascar is a biodiversity hotspot. Just as Darwin's finches on the Galápagos were isolated, evolving into distinct species (hello, adaptive radiation), over 90% of the wildlife from Madagascar is found nowhere else. 

The island's diverse ecosystems, like so many on this planet, are threatened by Earth's most deadly species, homo sapien sapiens. 

We arrived back in 490 CE and have been chopping down trees and eating our way through the island's tastier populations ever since. Still, they have cuties like this Red-Tailed Lemur. Awe, right?

Today, beautiful outcrops of wonderfully preserved fossil marine fauna hold appeal for me. The material you see from Madagascar is distinctive — and prolific.

Culturally, you'll see a French influence permeating the language, architecture and legal process. There is a part of me that pictures these lovely Lemurs chatting away in French. "Ah, la vache! Regarde le beau fossile, Hérissonne!"

We see the French influence because good 'ol France invaded sleepy Madagascar back in 1883, during the first Franco-Hova War. Malagasy (the local Madagascarian residents) were enlisted as troops, fighting for France in World War I.  During the Second World War, the island was the site of the Battle of Madagascar between the Vichy government and the British. By then, the Malagasy had had quite enough of colonization and after many hiccuping attempts, reached full independence in 1960. Colonization had ended but the tourist barrage had just begun. You can't stop progress.

ANAHOPLITES PLANUS OF VILLEMOYENNE QUARRY

A beautiful specimen of the ammonite, Anahoplites planus (Mantell, 1822) from Albian deposits in Villemoyenne Quarry, Courcelles, Aube, north-central France.

Anahoplites (Hyatt, 1900) is a genus of compressed hoplitid ammonites with flat sides, narrow, flat or grooved venters, and flexious ribs or striae arising from weak umbilical tubercles that end in fine dense ventrolateral nodes.

This lovely has attracted some roommates — an oyster, some bryozoans and worm tubes are attached to her shell.

Anahoplites is now included in the subfamily Anahoplitinae and separated from the Hoplitinae where it was placed in the older in the 1957 edition of the Treatise on Invertebrate Paleontology, Part L (Ammonoidea). Genera of the Hoplitinae tend to be more robust, with broader whorls and stronger ribs.

Anahoplites is found in Cretaceous (Middle to the Late Albian) deposits from England, through Europe, all the way to the Transcaspian Oblast region in Russia to the east of the Caspian Sea. The Aube department, named after the local river, is the type locality of the Albian stage (d'ORBIGNY, 1842). 

A. planus from the French Coast

Two formations are recognized in the clay facies (the "Gault" auct.) of the stratotype, the Argiles tégulines de Courcelles (82 m), overlain by the Marnes de Brienne (43 m). The boundary between the two formations is well-defined at the top of an indurated bed and readily identifiable in the field.

This involute (113 mm) specimen shows evidence of cohabitation by some of his marine peers. 

We see two different bryozoa, an oyster and some serpulids making a living and leaving trace fossils on her flat sides. The top specimen was prepared with potase by José Juárez Ruiz of Spain. 

The lovely Anahoplites planus you see here to the lower right was found by Bertus op den Dries on the French coast in Albian deposits near Wissant, P5 and measures in at 8 cm. This on edge view gives you a very good sense of the keel.

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.

DANCING ATOMS: AURORA BOREALIS

If you live in the northern hemisphere, you stand a very good chance of seeing the aurora borealis this evening. We had a spectacular showing last night. Their glorious dancing lights will be most visible from 11PM-4AM PST with their brilliance tapering off over the next few days.

Even with a fair bit of light pollution, you can see the colours quite clearly. Tonight's best showing is in the late afternoon to early evening. I am excited to see what we will see. 

The Earth has a magnetic field with north and south poles. The lights we see are the result of severe storms that push protons past their normal threshold around these two polar regions.  

The magnetic field of the Earth is surrounded by the magnetosphere which keeps most of the particles from the Sun from hitting the Earth. Some of these particles from the solar wind enter the atmosphere at one million miles per hour. The auroras occur when highly charged electrons from the solar wind interact with elements in the Earth's atmosphere and become trapped in the Earth's magnetic field. 

We see them as an undulating visual field of red, yellow, green, blue and purple dancing high in the Earth's atmosphere — about 100 to 400 kilometres above us. The green is the result of millions of oxygen atoms dancing like gleeful children as they decay back to their original state. 

The red is also caused by oxygen atoms but because those atoms are higher up in the atmosphere we register much of their vivid colour as green or reddish-green because of our poorly developed eyesight and lower red light emissions. 

Nitrogen atoms are a bit more standoffish. They get in on the action but only if the storm winds are very strong as it takes quite a hard hit to excite them. 

If you have been in the quiet northern regions for an aurora storm, you can hear their clapping sounds. On cold, clear nights, with light wind, a temperature inversion can form. This happens when a layer of relatively warm air creates a blanket over a shallow layer of cold air. 

Solar winds excite the atoms in the inversion layer, with opposite charges building up in the colder layer near the ground. When the aurora increases in intensity, geomagnetic disturbances travel down through the atmosphere causing the two layers to spark. 

We hear that electric discharge or spark as a click, click, click, clapping or banging sound. 

All science aside, what we see from these rare energetic interactions is one of the most beautiful of all-natural phenomena — Earth's polar lights, the aurora borealis in the north and the aurora australis, near the south pole. Vancouver had a wonderful surprise viewing a few weeks ago and tonight looks like it will provide another. 

The aurora borealis is best viewed in the north, of course, and many of my relatives have a bird's-eye view. To the Tlingit First Nation of Alaska, the aurora is Gis'óok. In Norway, the aurora is Nordlys — and by any name, spectacular.

GINKO: THE MAIDENHAIR TREE

Living and Fossil Ginko biloba

The gorgeous yellow lobed leaf you see here is from a Maidenhair Tree — Ginko. These lovelies grow slowly but are well worth the effort with their delicate and distinctive lobed leaves of green and yellow. 

Ginko are Living Fossils native to China. We find them in the fossil record as far back as the Permian, 270 million years, rising with cycads, seed ferns and early conifers. They were part of the low, open, shrubby canopy covering our world well before the first flowering plants arrived. 

Ginko grew when Weigeltisaurus jaekeli, the oldest gliding vertebrates first soared our ancient skies and the first wee beetles munched on decaying wood on our forest floors. It is the long history of predation by beetles and their friends that have made Ginko what they are today — hardy, stinky and weaponized. 

These trees are truly a wonder. Consider that they have lasted since the Permian, living through multiple extinction events that wiped out millions of species on the planet. They are one of the few living things to survive a recent human-made extinction event — the atomic bomb blast in Hiroshima, Japan on August 6, 1945 — weathering one of the most horrifying moments in human history. 

170 Ginko Survived the Atomic Bombing of Hiroshima

When the bomb dropped on Hiroshima it created a fireball that bloomed 1,200 feet in diameter, vaporizing most everything in its radius. 

Somehow 170 resident Gingko trees withstood the ferocity and heat of that blast — and they are still standing to this day, 76 years later. Seemingly impossible, and yet quite true. It is because of their hardy nature that we began looking closely at their genetic make-up. 

Plants with seeds are either angiosperms, our showy flowering plants, or gymnosperms, the naked seed plants. Ginkgo are gymnosperms but in their own subclass, Ginkgoidae. The ginkgos we see growing today are the last remaining member of that subclass.

We see Ginko's rise and diversify in the Permian. By the Jurassic, they had spread across Laurasia, the lands that would become modern Asia. It is this lucky foothold in a young Asia that would eventually save their species. 

From the Jurassic to the Pleistocene their numbers slowly dwindled. We have some great Eocene fossils from outcrops at Quilchena, Tranquille and the McAbee Fossil Beds that show them doing quite well in the interior of British Columbia some 50 million years ago, but this pocket of lush growth seems the exception and not the norm. 

By the Pleistocene, just 2.5 million years ago, glaciation threatened to kill off the last of the ginkgo lineages. Their last stand and platform for global distribution once again was rooted in the forests of central China. Every Ginko you see today originated from that small foothold in China. 

While beautiful, Ginkgo are stinky. I was out for a late stroll the night before last to try and catch a glimpse of the Aurora Borealis up at Queen Elizabeth Park. As I walked along one of the darkened pathways, my nose caught a whiff of something smelly. Think vomit mixed with decaying leaf matter. I looked up to confirm the culprit, a gorgeous bright yellow Ginko backlit from above. 

Ginko in Dan & Lena Bowen's Garden

The reason for their terrible smell is quite clever. It is the result of the chemicals they produce to ward off insects, fungi and bacteria. 

Ginko boast a massive genome comprising some 10.6 billion DNA letters within each strand. You and I boast only three billion letters in our human genome.

Written within this vast genetic code are 41,840 genes or templates that the tree’s cells use to make complex protein molecules that build and maintain each tree and give these stinky lovelies an enviable anti-insect arsenal. 

The photo at the top shows the yellow lobed leaves of a Ginko biloba against an Eocene partial lobe from the McAbee Fossil Beds up near Cache Creek, British Columbia, Canada. The bright yellow is this tree's Autumn colour palette. The bright green leaves you see in the bottom photo are the summer colour palette of this same species. The photo was taken in the summer in Dan and Lena Bowen's garden during the VIPS Saber-toothed Salmon Barbeque. This year, Dan-the-Man is saving some of those lovely lobed leaves to make up some tea from one of the oldest living species in the world. I am excited to give it a try. 

LOVE IN THE NORTH

Nunatsiarmiut Mother and Child, Baffin Island, Nunavut

Warm light bathes this lovely Nunatsiarmiut mother and child from Baffin Island, Nunavut. 

They speak Inuktitut, the mother tongue of the majority of the Nunatsiarmiut who call Baffin Island home. 

Baffin is the largest island in the Arctic Archipelago in the territory of Nunavut in Canada's far north—the chilliest region of Turtle Island. 

As part of the Qikiqtaaluk Region of Nunavut, Baffin Island is home to a constellation of remote Inuit communities each with a deep cultural connection to the land—Iqaluit, Pond Inlet, Pangnirtung, Clyde River, Arctic Bay, Kimmirut and Nanisivik. 

The ratio of Inuit to non-Inuit here is roughly three to one and perhaps the reason why the Inuktitut language has remained intact and serves as the mother tongue for more than 36,000 residents. Inuktitut has several subdialects—these, along with a myriad of other languages—are spoken across the north.  

If you look at the helpful visual below you begin to get a feel for the diversity of these many tongues. The languages vary by region. There is the Iñupiaq of the Inupiatun/Inupiat; Inuvialuktun of the Inuinnaqtun, Natsilingmiutut, Kivallirmiutut, Aivilingmiutut, Qikiqtaaluk Uannanganii and Siglitun. Kalaallisut is spoken by many Greenlandic peoples though, in northwest Greenland, Inuktun is the language of the Inughuit.

We use the word Inuktitut when referring to a specific dialect and inuktut when referring to all the dialects of Inuktitut and Inuinnaqtun.

Should you travel to the serene glacier-capped wilds and rolling tundra of our far north, you will want to dress for the weather and learn a few of the basics to put your best mukluk shod feet forward. 

The word for hello or welcome in Inuktitut is Atelihai—pronounced ahh-tee-lee-hi. And thank you is nakurmiik, pronounced na-kur-MIIK.  

Perhaps my favourite Inuktitut expression is Naglingniq qaikautigijunnaqtuq maannakautigi, pronounced NAG-ling-niq QAI-kau-ti-gi-jun-naqtuq MAAN-na-KAU-ti-gi. This tongue-twister is well worth the linguistic challenge as it translates to love can travel anywhere in an instant. Indeed it can. 

So much of our Indigenous culture is passed through stories, so language takes on special meaning in that context. It is true for all societies but especially true for the Inuit. Stories help connect the past to the present and future. They teach how to behave in society, engage with the world and how to survive in the environment. They also help to create a sense of belonging. 

You have likely seen or heard the word Eskimo used in older books to refer to the Inuit, Iñupiat, Kalaallit or Yupik. This misnomer is a colonial term derived from the Montagnais or Innu word ayas̆kimew—netter of snowshoes. 

It is a bit like meeting a whole new group of people who happen to wear shoes and referring to them all as cobblers—not as a nickname, but as a legal term to describe populations from diverse communities disregarding the way each self-refer. 

Inukshuk / Inuksuk Marker Cairn

For those who identify as Inupiaq or Yupik, the preferred term is Inuit meaning people—though some lingering use of the term Eskimo lives on. The Inuit as a group are made up of many smaller groups. 

The Inuit of Greenland self-refer as Kalaallit or Greenlanders when speaking Kalaallisut. 

The Tunumiit of Tunu (east Greenland), speak Tunumiit oraasiat ("East Greenlandic"); and the Inughuit of north Greenland, speak Inuktun "Polar Eskimo."

The Inupiat of Alaska, or real people, use Yupik as the singular for real person and yuk to simply mean person.

When taken all together, Inuit is used to mean all the peoples in reference to the Inuit, Iñupiat, Kalaallit and Yupik. Inuit is the plural of inuk or person. 

You likely recognize this word from inuksuk or inukshuk, pronounced ih-nook-suuk — the human-shaped stone cairns built by the Inuit, Iñupiat, Kalaallit, Yupik, and other peoples of the Arctic regions of northern Canada, Greenland, and Alaska—as helpful reference markers for hunters and navigation. 

The word inuksuk means that which acts in the capacity of a human, combining inuk or person and suk, as a human substitute. 

A World of Confusion

You may be disappointed to learn that our northern friends do not live in igloos. I remember answering the phone as a child and the fellow calling was hoping to speak to my parents about some wonderful new invention perfect for use in an igloo. 

The call came while I was in the kitchen of our family home in Port Hardy. He was disappointed to hear that I was standing in a wooden house with the standard four walls to a room and a handy roof topping it off. 

I also had my own room with Scooby-Doo wallpaper, but he was having nothing of it.

"Well, what about your neighbours? Surely, a few of them live in igloos..." 

It seems that some atlases in circulation at the time, and certainly the one he was looking at, simply blanketed everything north of the 49th parallel in a snowy white. His clearly showed an igloo sitting proudly in the centre of the province.

My cousin Shawn brought one such simplified book back from his elementary school in California. British Columbia had a nice image of a grizzly bear and a wee bit further up, a polar bear grinned smugly. 

British Columbia's beaver population would be sad to know that they did not inhabit the province though there were two chipper beavers with big bright smiles—one in Ontario and another gracing the province of Quebec. Further north, where folk do build igloos, their icy domes were curiously lacking. 

Igloos are used for winter hunting trips much the same way we use tents for camping. The Inuit do not have fifty words for snow—you can thank the ethnographer Franz Boas for that wee fabrication—but within the collective languages of the frozen north there are more than fifty words to describe it. And kisses are not nose-to-nose. To give a tender kiss or kunik to a loved one, you press your nose and upper lip to their forehead or cheek and rub gently.
