A team of paleontologists has unearthed dinosaur bones near Tumbler Ridge, British Columbia, that could be as old as 75 million years, reported The Associated Press. Rich McCrea and Lisa Buckley said Thursday that the bones from the Upper Cretaceous period are from the duck-billed dinosaur Hadrosaur and a Tyrannasaur, the big predator of the era. McCrea and Buckley said they found 90 kilograms of bone just sitting on the surface of a sloping bank just north of Tumbler Ridge this week. McCrea said they discovered broken or shed Tyrannasaur teeth near rib and vertebrae of a Hadrosaur.
