Scientists at the Royal Tyrrell Museum of Palaeontology, Canada, have discovered the diet of a young gorgosaurus, a type of tyrannosaur, with the help of a unique fossil. The fossil of the creature was discovered in 2009 in the Alberta Badlands, Canada, and its stomach contents were studied. Scientists found that the gorgosaurus had consumed two baby dinosaurs of the Citipes elegans species. Both the dinosaurs were less than a year old and the gorgosaurus had eaten their hind legs. The gorgosaurus was approximately seven years old and its weight was around 13% of a fully-grown adult of its species. According to scientists, adult gorgosauruses preyed on big herbivorous dinosaurs, while the young ones preferred to prey on smaller dinosaurs. The study shows that the creatures’ diet changed as they grew.
