Fossil Bites Into Mammal Stereotypes Paleontologists uncovered the fossil of a large beaver-like mammal in China that lived on land and likely fished in lakes. The discovery could tear down previous stereotypes that mammals, while living alongside dinosaurs, could not develop extensive specialization. |
