Insights into Tyrannosaur Diets: Fossil Reveals Final Meals and Changing Preferences

A tyrannosaurus fossil has provided scientists with new insights into the carnivore's diet. The fossil of a gorgosaurus libratus, part of the tyrannosaurid group that includes the T. rex, contained the preserved hind limbs of two yearling caenagnathid dinosaurs inside its abdominal cavity. This discovery suggests that young tyrannosaurids may have hunted small dinosaurs until they grew bigger and began to feed on larger prey. The findings also indicate that tyrannosaurids played both mesopredator and apex predator roles in their lifetime, contributing to their evolutionary success.

The Unique Features of the Marsupial Sabertooth.

Thylacosmilus atrox, a "marsupial sabertooth" that lived in South America 5 million years ago, had massive ever-growing canines that required skull adaptations. Its eyes were on the side of its head like a horse, allowing for panoramic-like vision to achieve depth perception. Thylacosmilus was a hypercarnivore, but not capable of high-speed pursuit of prey. Instead, it likely lay in ambush and waited for prey to come along. The animal went extinct due to environmental changes altering the landscape of South America 3 million years ago.
