Mammal eats Dinosaur

IVPP and AMNH scientists published the first evidence that Mesozoic mammals munched on dinosaurs. The paper, published in the journal Nature, shows an exquist skeleton of a new species of Repenomamus from the basal member of the early Cretaceous Yixian Formation in Liaoning, China. This new fossil mammal was huge! (well at least compared to other Mesozoic mammals, about the size of a living possum). Repenomamus is a Triconodont mammal, which are normally very tiny. In the gut, limbs and teeth were found of a juvenile Psittacosaurus, a common dinosaur from the Yixian Formation.
