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.

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 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.
