Prehistoric Models: Chiroptera
Mammals are a class animals defined as warm-blooded vertebrates, distinguished by the possession of hair or fur, the secretion of milk by females for the nourishment of the young, and (typically) the birth of live young (with only two modern exceptions).
Bats are classified in the Order of Chiroptera meaning “hand wing”. The earliest bat fossils are from the Eocene Epoch some 50 million years ago. Bats are the second largest Order in the Class Mammalia, they are only outnumbered by Rodents.
