Teenage Tyrannosaur's Fossilized Stomach Unveils Prey Preference

The fossil of a 75-million-year-old Gorgosaurus, a relative of Tyrannosaurus rex, has been discovered with preserved stomach contents, providing insight into the feeding behavior of young tyrannosaurs. The fossil contains the hind limbs of two small feathered dinosaurs, indicating that young tyrannosaurs fed on different animals than their adult counterparts. This finding supports the theory that young tyrannosaurs were nimble predators, filling a midsize predator niche before maturing into apex predators. The fossil also suggests that Gorgosaurus could not take on large herbivores until the age of 11.

Ancient Tyrannosaur Fossil Unveils Perfectly Preserved Stomach Contents

A 75-million-year-old fossil of a juvenile Gorgosaurus has been discovered with its stomach contents intact, making it the first-ever Tyrannosaur found with preserved stomach contents. The fossil reveals that the picky eater consumed the legs of two small feathered dinosaurs, likely a popular menu item at the time. The finding sheds light on the dietary habits of juvenile Tyrannosaurs and suggests that their diets changed as they grew older, allowing them to occupy different ecological niches and become successful predators.

"Tyrannosaur's Last Meal: A Prehistoric Surprise Found in Stomach Fossil"

Scientists have discovered the remains of prey inside the stomach of a tyrannosaur skeleton for the first time, shedding light on the dietary habits and growth patterns of these mighty dinosaurs. The Gorgosaurus, a member of the tyrannosaurid family, had the remains of two young bird-like dinosaurs called Citipes in its stomach. This finding suggests that young tyrannosaurs had a different diet than their adult counterparts, transitioning from smaller prey to larger plant-eating dinosaurs as they grew. The discovery provides insight into the ontogenetic dietary shift of tyrannosaurs and their success as apex predators.

T. rex cousin's stomach reveals dismembered young dinosaurs

Fossilized remains of a juvenile Gorgosaurus, a cousin of the T. rex, have been discovered in Canada's Alberta province, revealing its last meals. The 5 to 7-year-old Gorgosaurus had preyed on turkey-sized yearlings of a feathered plant-eating dinosaur called Citipes. This is the first tyrannosaur skeleton with preserved prey items inside its stomach, providing insight into the changing feeding strategies and diets of tyrannosaurs during their lifespan. The study suggests that young tyrannosaurs occupied different ecological niches as "mesopredators" while adults were apex predators, indicating they did not compete for the same prey.
