Repenomamus (Latin: "reptile" (reptilis), "mammal" (mammalis)[2]) is a genus of opossum- to badger-sized gobiconodontid[3] mammal containing two species, Repenomamus robustus and Repenomamus giganticus. Both species are known from fossils found in China that date to the early Cretaceous period, about 125-123.2 million years ago. R. robustus is one of several Mesozoic mammals[7] for which there is good evidence that it fed on vertebrates, including dinosaurs. Though it is not entirely clear whether or not these animals primarily hunted live dinosaurs or scavenged dead ones, evidence for the former is present in fossilized remains showcasing the results of what was most likely a predation attempt by R. robustus directed at a specimen of the dinosaur Psittacosaurus lujiatunensis.[8] R. giganticus is among the largest mammals known from the Mesozoic era, only surpassed by Patagomaia.
