Ancient Tyrannosaur Fossil Unveils Perfectly Preserved Last Meal

Researchers have discovered the first tyrannosaur fossil with its last meal perfectly preserved in its stomach, providing hard evidence of the dinosaur's diet. The fossil, belonging to a young Gorgosaurus libratus, contained the hind legs of two baby dinosaurs called Citipes elegans. The findings suggest that juvenile tyrannosaurs had different diets from fully developed adults, and the preserved stomach contents shed light on the dietary patterns of large predatory dinosaurs. The discovery also supports the hypothesis that the voracious appetite of teenage tyrannosaurs and other carnivores may have contributed to the scarcity of small and midsize dinosaurs in the fossil record.
