Ancient Fossil Unveils Epic Battle: Mammal Takes on Dinosaur

A fossil discovered in China shows a badger-like mammal, Repenomamus robustus, biting into the ribs of a Psittacosaurus lujiatunensis dinosaur, suggesting that small mammals may have preyed on dinosaurs during the Cretaceous period. The fossil, which is the first of its kind, provides evidence that mammals were capable of taking down adult dinosaurs. The discovery was made at a site in China known as the "Chinese Pompeii" due to the abundance of preserved dinosaur and animal fossils.
