A 75-million-year-old fossil reveals a shocking tyrannosaur secret

A 75-million-year-old fossil has revealed that tyrannosaurs may have engaged in opportunistic behavior, with a smaller tyrannosaur feeding on the remains of a larger relative. This discovery was made possible through high-resolution 3D scans of a massive tyrannosaur foot bone. The findings suggest a more complex side to the behavior of these apex predators.
