A 76-million-year-old footprint discovery in Alberta's Dinosaur Provincial Park reveals that tyrannosaurs were likely stalking herds of herbivorous dinosaurs, providing new insights into predator-prey interactions and dinosaur social behavior during the Late Cretaceous period.
Scientists discovered a rare set of dinosaur footprints at Dinosaur Provincial Park in Alberta, revealing evidence of mixed-species herding behavior around 76 million years ago, including side-by-side tyrannosaur tracks that suggest predators may have stalked herds, providing new insights into dinosaur social behavior.
Scientists re-examined 86-million-year-old fossils from Mongolia, discovering a new species called Khankhuuluu mongoliensis, which is the most recent ancestor of tyrannosaurs. This slender, modest-sized predator helps fill a gap in the fossil record and sheds light on tyrannosaur evolution and migration patterns between Asia and North America. The study suggests that large tyrannosaurs like T. rex evolved later, after migrations of earlier species.
The well-preserved stomach of a 75 million-year-old Gorgosaurus libratus, a type of tyrannosaur, revealed the remains of baby bird-like dinosaurs, suggesting that the species' diet changed as they grew. The discovery, the first of its kind, provides insight into the feeding behavior of juvenile and adult tyrannosaurs, showing that juveniles were better suited to eat small prey while adults could consume much larger prey.

Researchers have discovered the well-preserved remains of baby bird-like dinosaurs inside the stomach of a young Gorgosaurus libratus, a type of tyrannosaur. This finding suggests that the diets of tyrannosaurs changed as they grew, with juveniles better suited to eat small prey and adults capable of consuming much larger prey. The discovery provides valuable insights into the feeding behavior and growth patterns of tyrannosaurs.
Paleontologists in Canada have discovered a 75-million-year-old fossilized skeleton of a juvenile tyrannosaurid dinosaur, Gorgosaurus libratus, with the remains of two young individuals of the small dinosaur Citipes elegans in its stomach. This finding provides direct evidence that young tyrannosaurs had different diets than their adult counterparts, suggesting a major dietary shift as they grew. Juvenile tyrannosaurs likely hunted small and young prey, while adults hunted large herbivores. The study sheds light on the ontogenetic dietary shifts of these iconic predators.
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.
