Repenomanus Robustus

Nice to meet you, mr Repenomanuss robustus

Repenomanuss robustus was a cat-size, weasel-like mammal with large pointy teeth and powerful jaws, that fed on small dinosaurs. One 130-million-year-old fossil specimen was found with the remains of a small beaked dinosaur called Psittacosaurus in it's stomach. The dinosaur was a juvenile. The remains suggest it was wolfed down in chunks rather than chewed. It's not know whether Repenomanus robustus  hunted the dinosaur or scavenged it, but it had strong legs and sharp teeth and could have easily been a hunter.
