Paleontologists in Canada have uncovered a first-of-its-kind fossilized meal after finding dinosaur "drumsticks" in the belly of a "teenage tyrannosaur." The unique fossils are the first direct evidence that these apex predators switched up their diets from early years to adulthood, a new study shows.

Researchers discovered the partial remains of the tyrannosaur — a group of large theropod dinosaurs that includes Tyrannosaurus rex — in 2009 within Dinosaur Provincial Park in southern Alberta.
