Mammalia

Mammals are a highly diverse group of animals charecterized by having hair or fur, a warm blooded metabolism, external ears and being able to produce milk. We humans are mammals ourselves. Although not quite as diverse as on HE, the Continued Age of Dinosaurs still has many many species and not all of them are small! The continued age of dinosaurs is also noted for having several lineages of basal mammals that went extinct on Earth, although not as many as some scientists had hoped.
