Joffre Bridge — an amazing Late Palaeocene deposit of incredibly well-preserved fossil plants, including leaves, seeds, whole plants, and trees. Fossil flora include lycopsids, Ginko , Equisetum, Metasequoia , and many others. The Burgess Shale is one of the most important and oldest fossil sites in the world, containing a diverse assemblage of bizarre late Cambrian fossils, including Hallucigenia , Anomalocaris , and trilobites, and many soft-bodied organisms.
The rules in Canada are much more strict than in the United States. It is illegal to collect fossils in Canada without permits, and those can only be given to professional palaeontologists that work for the government, museums, or universities. Even palaeontologists cannot claim ownership over the fossils on which they work. Barclay K.

However, complete skeletons are rare. When one is left with only a single bone or tooth, they must compare it to other better-known specimens. Only when you find something that closely matches your bone can you can make an educated guess as to what the rest of the animal looked like.
Nevertheless, such reconstructions are always tentative and may require changes and remodeling when new material is found. What colour were dinosaurs? Until very recently, this question would have been answered with a shrug; however, thanks to some spectacular fossils from China, we are starting to get an idea of what at least some dinosaurs would have looked like.
Although colour does not fossilize, scientists have identified colour-specific proteins that are responsible for black and rusty hues. The hair on the tail at least one little dinosaur called Sinosauropteryx , was stripy with reddish hues. How fast could dinosaurs run? It is difficult to understand how exactly an animal moved, especially one that has been extinct for 65 million years.
Perhaps the best evidence comes from dinosaur trackways. By observing modern animals, R. McNeill Alexander recognised a relationship between the size of an animal, its footprints, and how widely-spaced apart they are. Using this equation, palaeontologists have estimated speeds from a variety of trackways. Who gets to name a new species of dinosaur? For a new species to be named, a palaeontologist or team of palaeontologists must first determine what exactly makes this particular animal different from all other species.
Only then will they come up with a name. For example, the Thanatotheristes fossil indicates that tyrannosaurs were a highly diverse species. Research indicates that tyrannosaurs did not share one general body type. In fact, different tyrannosaur species evolved their own distinct body shapes, skull sizes, and other physical features.
These features corresponded with their specific environment. This new exciting find will soon be on display at the Royal Tyrell. Thanatotheristes is another great tyrannosaur find for paleontologists in Alberta.
This unique find contains the footprints of several dinosaurs. Scientists believe that at least nine different dinosaur species migrated through Alberta some million years ago. In their path they left behind thousands of footprints in the mud. The mud has transformed into steep sheet rock near Grand Cache in northern Alberta. The footprints found in the rock are some of the most extensive dinosaur trackways in the world. There are more than a dozen trackway sites within 25 square kilometers of the site.
The most common footprint comes from an armoured dinosaur. The Grand Cache Trackways are an important discovery for paleontologists. They demonstrated how dinosaurs moved in three meter strides.
They also provide information on how dinosaurs lived in groups. Scientists believe this crest indicates age or species. Or, because of the vibrant colours, male Edmontosaurus used the crest to attract mates.
Whatever its use, the crested Edmontosaurus offers an exciting clue. Other dinosaur s may have sported a large, colorful crest on their heads. Dinosaurs are synonymous with Alberta. Countless dinosaur species have been discovered in Alberta. Some of the most impressive include the Albertasaurus, crested Edmontosaurus, and the Borealopelta markmithelli.
Dinosaurs are not the only fossils found in the province. The Grand Cache trackways and the feathers in amber are two incredible paleontological finds. Alberta is also replete with dinosaur museums.

As studies become more sophisticated, palaeontologists are revealing aspects of dinosaur physiology, variation, and behaviour. Extinction theories abound, but the evidence is favouring an asteroid hitting the Earth 65 million years ago. But did they really die out? It is now widely accepted that more than species are alive today. We call them birds. Coal was a strategic resource and its discovery was paramount for the success of the railway and expansion of Canada.
More important than the dinosaurs were the other fossils they discovered. These were the only means they had of determining the age of the rocks they were mapping. While exploring for coal in , Tyrrell made the first discovery of a dinosaur in the Red Deer River Valley. This was a skull of Albertosaurus. It was his most famous fossil collection, but nearly as important were the many invertebrate fossils he collected.
