A dinosaur fossil found in the Alberta badlands has revealed new details about the diet of young meat-eating tyrannosaurs.
The research, published Friday in the journal Science Advances, is based on a well-preserved Gorgosaurus libratus specimen discovered in 2009 by a technician from the Royal Tyrrell Museum in Drumheller, Alta.
“We describe the first tyrannosaur skeleton found with prey items preserved inside the stomach,” Darla Zelenitsky, an associate professor in the department of earth, energy and environment at the University of Calgary, said in an interview.
