TECTONIC SHIFTING: BAJA BC

Some 270 million plus years ago, had one wanted to buy waterfront property in what is now British Columbia, you’d be looking somewhere near Kakwa Provincial Park between Prince George and the Alberta border. 

The rest of the province had yet to arrive but would be made up of over twenty major terranes from around the Pacific. 

The rocks that would eventually become the Cariboo Mountains were far out in the Pacific Ocean, down near the equator.

With tectonic shifting, these rocks drifted north-eastward, riding their continental plate, until they collided with and joined the Cordillera in what is now British Columbia. Continued pressure and volcanic activity helped create the tremendous slopes of the Cariboo Range we see today with repeated bouts of glaciation during the Pleistocene carving their final shape.

FARALLON PLATE

The Farallon Plate took a turn north some 57 million years ago, sweeping much of western coastal Oregon along with it. 

By the middle Oligocene, the Cascadia Subduction Zone was in full force with growing pressure erupting volcanoes along the Western Cascades, a pattern that was to continue well into the Miocene. 

The soft ocean sediments of Oregon contain beautifully preserved gastropods, bivalves and cephalopods.

PADDLERS PARADISE


BIRTHPLACE OF ANTAEUS

Quintus Sertorius, a Roman statesman come general, grew up in Umbria, the green heart of what is now central Italy.

Born into a world at war just two years before the Romans sacked Corinth to bring Greece under Roman rule, Quintus lived much of his life as a military man far from the hills, mountains, and valleys of his birthplace.

In 81 BC, he traveled to Morocco, the land of opium, massive trilobites and the birthplace of Antaeus, the legendary North African ogre who was killed by the Greek hero Heracles.

The locals tell a tale that Quintus requested proof of Antaeus, hard evidence he could bring back to Rome to support their tales so they took him to a mound at Tingis, Morocco, where they unearthed the bones of a Neogene elephant, Tetralophodon.

During the Miocene and Pliocene, 12-1.6 million years ago, this diverse group of extinct proboscideans, elephant-like animals walked the Earth.

Most of these large beasts had four tusks and likely a trunk similar to modern elephants. They were creatures of legend, inspiring myths and stories of fanciful creatures to the first humans to encounter them.

Tetralophodon bones are large and skeletons singularly impressive. Impressive enough to be taken for something else entirely. By all accounts these proboscidean remains were that of the mythical ogre Antaeus and were thus reported back to Rome as such. It was hundreds of years before their true heritage was known.

I was lucky enough to travel to Morocco a few years ago and see the Tetralophodon remains. At the time, the tales of Antaeus ran through my head. Could this be the proof that Quintus wanted. As it happens, it was.

ROCKY MOUNTAIN HIGH


METASEQUOIA

Metasequoia (dawn redwood) is a fast-growing, deciduous tree native to Lichuan county in Hubei province in central China. It is the sole living species of Metasequoia glyptostruboides. It is one of three species of conifers known as redwoods.

Although the least tall of the redwoods, it grows to at least 200 feet (60 meters) in height. Local villagers refer to the original tree from which most others derive as Shui-sa, or "water fir", which is part of a local shrine. Since its rediscovery in 1944, the dawn redwood has become a popular ornamental tree in the Pacific Northwest. Metasequoia was first described as a fossil from the Mesozoic Era by Shigeru Miki in 1941. Later in 1944, a small stand of an unidentified tree species was discovered in China in Modaoxi (磨刀溪; presently, Moudao (谋道), in Lichuan County, Hubei province by Zhan Wang. 

While the find was exciting, it was overshadowed by China's ongoing conflict with Japan. In 1937, a clash between Chinese and Japanese troops at the Marco Polo Bridge, just outside Beijing, led to an all-out war. A year later, by mid-1938, the Chinese military situation was desperate. Most of eastern China lay in Japanese hands: Shanghai, Nanjing, Wuhan. Many outside observers assumed that China could not hold out, and the most likely scenario was a Japanese victory over China. Yet the Chinese hung on, and after Pearl Harbor, the war became genuinely global. The western Allies and China were now united in their war against Japan, a conflict that would finally end on September 2, 1945. 

With World War II behind them, the Chinese researchers were able to re-focus their energies on the sciences. In 1946, Wan Chun Cheng and Hu Hsen Hsu were able to further study the trees from Lichuan County and publish their work describing a new living species of Metasequoia in 1948. That same year, Arnold Arboretum of Harvard University sent an expedition to collect seeds and, soon after, seedling trees were distributed to various universities and arboreta worldwide for growth trials.

TACHYGLOSSIDAE — MONOTREMES

This chunky monkey is a Short-beaked Echidna, Tachyclossus aculeatus, which grows to about the size of an overweight cat. They are native to Australia and New Guinea. 

Echidnas are sometimes called spiny anteaters and belong in the family Tachyglossidae (Gill, 1872). They are monotremes, an order of egg-laying mammals. There are four species of echidnas living today. They, along with the platypus, are the only living mammals who lay eggs and the only surviving members of the order Monotremata. 

Superficially, they resemble the anteaters of South America and other spiny mammals like porcupines and adorable hedgehogs. They are usually a mix of brown, black and cream in colour. While rare, there have been several reported cases of albino echidnas, their eyes pink and their spines white. Echidnas have long, slender snouts that act as both nose and mouth for these cuties. The Giant Echidna we see in the fossil record had beaks more than double this size.

LATE JURASSIC CADOCERAS TONNIENSE

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.

MIDDLE TRIASSIC-ANISIAN AMMONOID

A specimen of Grambergia sp., a Middle Triassic-Ansian ammonoid from the Toad Formation of northeastern British Columbia.

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 SP. (STERCULIACEAE)

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.

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!

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.
