Discovery of Dinosaur Tail in Canada Sheds Light on North America's Prehistoric Fauna
Researchers have discovered an 80-million-year-old dinosaur tail on Denman Island, off the coast of British Columbia, Canada. This fossil is believed to belong to an ornithomimosaur, a type of fast-running, bird-like theropod dinosaur that lived during the Cretaceous period, approximately 145 to 66 million years ago. The tail bone, identified as the 10th bone of the caudal vertebra, was found isolated and is thought to have been deposited on the island by a floating carcass or transported by another scavenging dinosaur. The discovery was made through CT scans and 3D modeling, which compared the fossil to known ornithomimosaur and tyrannosaur skeletons. This finding provides the clearest evidence yet that these ostrich-like dinosaurs once roamed the Pacific coastline of North America.
