IN SEARCH OF TRIASSIC BEASTIES

So, what's next in the story of marine reptiles and dinosaurs? Where are the next big finds to be found?

Well, if finds like Shonisaurus sikanniensis are any indication, my guess would be northern British Columbia.

After almost no large finds over the past hundred years, they have revealed the largest marine reptile on record, along with countless terrestrial finds that make that area one of the richest searching grounds on the globe.

There are Triassic marine outcrops in northern British Columbia that extend from Wapiti Lake to the Yukon border. Without the fossil finds, this area is just pure, raw Canadian gold in terms of scenery and environmental importance. Well worth exploring for its sheer beauty.

With the paleontological possibilities, it's the stuff of dreams. The big reveal may be new species of dinosaurs, large marine reptiles and greater insight into their behaviour and interactions deep in the Triassic.

I'm excited for the future of paleontology in the region as more of these fruitful outcrops are discovered, collected and studied.

EOCENE LOVE BUG

The Love Boat, soon you'll be sailing away... Well, perhaps you will but that ship has sailed for this wee fellow.

This is a Fossil Love Bug, one of the most satisfying fossils to collect in the Eocene deposits of Princeton, British Columbia.

Love Bugs or March Flies are hardy, medium-sized flies in the Order Diptera, with a body length ranging from 4.0 to 10.0 mm. The body is black, brown, or rusty, and thickset, with thick legs. The antennae are moniliform. The front tibiae bear large strong spurs or a circlet of spines. The tarsi are five-segmented and bear tarsal claws, pulvilli, and a well-developed empodium.

As it is with many species, these guys included, the teens of this species are troublesome but the adults turn out alright. As larvae, Bibionidae are pests of agricultural crops, devouring all those tasty young seedlings you've just planted.

Then, as they mature their tastes turn to the nectar of flowers from fruit trees and la voila, they become your best friends again. With their physical and behavioral transformation complete, Bibionidae become a welcome garden visitor, pulling their weight in the ecosystems they live in by being important pollinators.

AMMONITE CRUSHED BY PREDATOR

Here a partial ammonite with lovely oil-spill coloured nacre (ammolite) shows several bite marks.

One of the natural predators to ammonites were the marine reptiles, particularly mosasaurs and elasmosaurs.

Mosasaurs, while robust predators, lived nearer to the ocean surface, preying on fish, turtles, birds, and sadly for this fellow, ammonites.

Ammonites were also prey to the elasmosaurs, a genus of plesiosaur that lived in the Late Cretaceous. With their long necks, the could move unseen in the depths then chomp down with their cage-like teeth to munch on fish and those unfortunate enough to be the tasty bounty of ancient times.

Florissantia, an extinct genus in the Cocoa Tree Family

Beautifully preserved specimens of Florissantia can be found in the Eocene deposits near Cache Creek in the Tranquile Formation, Kamloops Group, at Quilchena, Coldwater Beds, Kamloops Group and near Princeton, British Columbia in the Allenby Formation.

This specimen is from the Allenby Formation, which is predominately fine-grained shales and mudrocks. Florissantia are quite commonly found here alongside other plant remains and rarer, insect and fish fossils.

LAST CREEK | TYAUGHTON AMMONITE

SHELTER POINT, VANCOUVER ISLAND

Shelter Point on northern Vancouver Island is a lovely beach site and part of the Oyster Bay Formation, located just off the Island Highway, about 10km south of downtown Campbell River.  

At the northern end of Shelter Bay, turn east onto Heard Road, which ends at a public access to Shelter Point. A low tide is necessary in order to collect from these shales. I also recommend rubber boots and eye protection. This is a good family trip.   

The fossils, mainly the crab, Longusorbis and the straight ammonite Baculites, occur only in the gritty concretions that weather out of the shale. Aside from the fossils, check out the local tidepools and larger sea life in the area. Seals and playful otters can be seen basking on the beaches.

CRETACEOUS STEW: INOCERAMUS CLAMS

These oyster-like clams were common through the Jurassic and Cretaceous periods. The presence of certain fossil Inoceramus species allows geologists to date specific formations.

The entire group went extinct at the end of the Cretaceous, as did the ammonites and the dinosaurs.

This specimen from Hornby Island is approximately 67 million years old. They were was found a perfect sunny day while collecting with Graham Beard, author of West Coast Fossils and Chair of the Vancouver Island Museum Paleontological Society. Graham has a keen eye and knack for finding the best specimens on the island.

Visit his collection at the Qualicum Museum on Vancouver Island, British Columbia. It is well worth the trip!

Here you can see a theropod footprint found by Heidi Henderson, then Chair of the Vancouver Paleontological Society.

Rich McCrae, resident paleontologist and researcher at the site has published many first dinosaur finds from British Columbia. The specimen was donated to the Tumbler Ridge Paleontological Society.

ANKYLOSAUR TRACKWAY

After an exciting hike in the dark through the woods and down a steep incline, we reached the river. The tracks in this photo are from a type of armored dinosaur that date to the very end of the Cretaceous, between 68-66 million years ago.

Imagine a meandering armored tank munching on ferns, shrubs and other low-growing vegetation.

This is a photograph of an ankylosaur trackway filled with water and lit by lamplight along Wolverine River, a research site of Lisa Buckley, one of two magnificent paleontologists working in the area. 

Some of the prints contain skin impressions, which is lucky as many of the prints are so shallow that they can only be recognized by the skin impressions.

There are three types of footprints at the Wolverine River Tracksite - theropods (at least four different sizes) sauropods and ankylosaurs. Filling the prints with water and using light in a clever way was a genius idea for viewing tracks that are all but invisible in bright sunlight by day.

JOHN DAY FOSSIL BEDS

Oreodont skull, John Day Fossil Beds

More than a 100 groups of mammals and a wide variety of plants have been found in the early Miocene, 39-19 million year old, John Day Formation near Kimberly, Oregon.

The fossiliferous strata that have yielded beautifully preserved specimens of many of the animals we see domesticated today. Dogs, cats, swine and horses are common. Oreodonts, camels, rhinoceros and rodents have also been found in this ancient deciduous forested area.

Here my talented young paleontologist cousin Spencer is holding a well preserved Oreodont skull.Many sites in Oregon yield beautifully preserved fossil shells laid down over 60 million years. The asteroid that hit the Gulf of Mexico at the end of the Cretaceous caused a seafloor rift that split ancient Oregon. The massive hole left behind as the coastal lands slid northward filled in with sediment, refilling the basin.

These marine sediments were uplifted around the time of the birth of Oregon's Coastal Range. Easily collected and identified, as they look very similar to their modern cousins, you can dig for marine fossils all along Oregon's beachfront.

MOSQUE-CATHEDRAL, CORDOBA, SPAIN

A mix of Muslim and Christian architecture can be found in the stunning, and oh so grand Mosque-Cathedral in Cordoba, southern Spain. 

Originally a small temple of Christian Visigoth origin, the Catholic Basilica of Saint Vincent of Lérins has an unusual and collaborative history. 

When Muslims conquered Spain in 711, the church was divided into Muslim and Christian halves.

This sharing arrangement lasted until 784, when the Christian half was purchased by the Emir 'Abd al-Rahman I, who then demolished the original structure to build the grand mosque of Córdoba on its ground.

Córdoba returned to Christian rule in 1236 during the Reconquista, and the building was converted to a Roman Catholic church, culminating in the inclusion of a Renaissance cathedral nave in the 16th century. If you are visiting Andalusia, it is well worth a day trip. Bring your camera and comfortable shoes.

KOTSUIS AND HOHHUG: KWAKWAKWA'WAKA OF THE PACIFIC NORTHWEST

Kotsuis and Hohhug, Nakoaktok

This stunning image of Kotsuis and Hohhug, Nakoaktok — Nakoaktok men in ceremonial dress, with long beaks, crouching on their haunches was taken by Edward Curtis ca. 1914. 

Curtis photographed the Kwakwaka'waka ceremonial dress and masks on the west coast of British Columbia.

The Kwakwa̱ka̱’wakw (or Kwakiutl) are a collective of First Nation groups of the Pacific Northwest Coast. We view them as one people, and they are bound by language, but each had their own Chiefs, beliefs and ancestors. Collectively they cover the territory of British Columbia on northern Vancouver Island, some of the islands around Johnstone Strait and Queen Charlotte Strait and the adjoining mainland. 

United by the common language of Kwak'wala, the broad group can be divided into 13 nations, each with its own clan structure and distinct histories. According to Kwakwaka'wakw folklore their ancestors or ‘na’mima, came to a given spot — by way of land, sea, or underground — in the form of ancestral animals that upon arrival shed their animal appearance and became human.

The first documented contact with Westerners was in 1792 during the expedition led by English officer Captain George Vancouver, and was soon followed by colonies of Europeans settling on Canada's West Coast. 

As was often the way, with settlers came disease and the Kwakwaka’wakw population dropped by up to 75% between 1830 and 1880. Their distinctive ideas about wealth — that status came not from how much you owned but how much you were able to give away — came to the particular attention of the US anthropologist Franz Boas, who wrote extensively on their elaborate gift-giving ceremonies known as the potlach. 

The ceremonial practice was also a particular target of Christian missionaries who saw it as a major obstacle to their "civilizing" mission, and the Canadian government banned the practice in 1885 —although the act was soon amended, proving impossible to enforce.

This photograph of the ceremonial dress and masks of the Kwakwaka'wakw was the creation of American photographer and ethnologist Edward Curtis (1868–1952), famous for his work with First Nations and Native American people. 

Part of a project funded by banking magnate J.P. Morgan, these photographs are from the collection held at the Library of Congress and contain many images not published in Curtis' enormous twenty-volume The North American Indian. In 2015, Taschen produced their epic 768-page The North American Indian: The Complete Portfolios, which gathers Curtis’ entire American Indian portfolio into one publication.

SEAGULLS: 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.

HUMMINGBIRD: K'WA'AK'WAMT'A

Irridescent, quick of wing and oh, so beautiful — the wee lovers of nectar who grace our blossoms are hummingbirds.

In the Kwak̓wala language of the Kwakiutl or Kwakwaka'wakw, speakers of Kwak'wala, of the Pacific Northwest, hummingbirds are known as k̕wa̱'ak̕wa̱mt̕a.

TRIASSIC PAPER CLAMS

AMMONITE TIME KEEPERS

Argonauticeras besairei, José Juárez Ruiz

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

Ammonites were predatory, squidlike 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 am 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) Christophe Marot

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 it is found.

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 of rock to match up to specific geologic time periods, rather like the way we use tree rings to date trees. A handy way to compare fossils and date strata across the globe.
