Dinosaurs have been a topic of fascination for decades, and every new discovery brings us closer to understanding their lives. Recently, scientists uncovered the remains of a 75-million-year-old tyrannosaur, and the findings are nothing short of amazing.

The well-preserved fossil, belonging to a juvenile gorgosaurus, a close relative of the fearsome T. rex, has provided insights into the dietary habits of these ancient creatures. Dr. Darla Zelenitsky from the University of Calgary described the discovery as “solid evidence that tyrannosaurs drastically changed their diet as they grew up.”

This particular gorgosaurus, estimated to be around seven years old and weighing 330kg at the time of its death, had an unexpected last meal—two baby dinosaurs called citipes. The fossil revealed the hind limbs of these small feathered dinosaurs in its stomach.

The significance of this discovery lies in challenging previous assumptions about the diet of tyrannosaurs. It appears that as they matured, teenage tyrannosaurs like this gorgosaurus shifted their focus to hunting small, young dinosaurs rather than joining adults in hunting larger prey.

The fossilized remains, found in Canada’s Alberta Badlands in 2009, took years to prepare for study. The revelation opens new avenues for understanding the dynamic nature of tyrannosaurs’ diets as they progressed through different life stages.

The study, published in the journal Science Advances, sheds light on the intricacies of these ancient predators’ lives and how their dietary preferences evolved over millions of years.
