Canada Finds 75-80-Million-Year-Old Ornithomimosaur Fossil Off British Columbia

A tail vertebra recovered from Denman Island marine rocks gives the clearest evidence yet that ornithomimosaurs lived along North America’s ancient Pacific coast 75 million to 80 million years ago.
The fossil, collected in 1999 from the Cedar District Formation, is only the second reported dinosaur skeletal find from the Nanaimo Group and the first from Canadian outcrops.
Researchers said the bone likely reached offshore sediments after washing out from the western margin of ancient North America, possibly via currents, shoreline transport, scavengers or a drifting carcass.
The team linked the site’s ancient latitude to Campanian dinosaur-bearing formations farther east, but said more discoveries are needed to test whether Pacific coastal dinosaurs followed distinct diversity and biogeographic patterns.
