Dinosaur vs mammal: Dramatic fossil shows pugnacious mammal attacking a dinosaur

"Here, we have good evidence for a smaller mammal preying on a larger dinosaur, which is not something we would have guessed without this fossil," Mallon added.

Fossilized skeletons dating to about 125 million years ago from China showing the entanglement of the dinosaur Psittacosaurus lujiatunensis and the mammal Repenomamus robustus are seen in this 2022 handout photograph. Scale bar equals 10 cm.

Humans' ancestors, dogs, bats may have coexisted with dinosaurs – study

Primates, whom humans evolved from, rabbits and hares, dogs and cats were shown to have evolved just before the mass extinction, so they coexisted with dinosaurs.
