Volaticotherium antiquum Meng et al., 2006 |
Volaticotherium antiquum was an ancient gliding mammal not closely related to any other mammalian group currently known. It had a gliding membrane similar to a modern-day flying squirrel. The teeth of Volaticotherium were highly specialized for eating insects, and its limbs were adapted to living in trees. The gliding membrane (patagium) was insulated by a thick covering of fur, and was supported by the limbs as well as the tail. The discovery of Volaticotherium provided the earliest-known record of a gliding mammal (70 million years older than the next oldest example), and provided further evidence of mammalian diversity during the Mesozoic Era.
Volaticotherium fossils were recovered from the Daohugou Beds of Ningcheng County, Inner Mongolia, China. The age of the Daohugou Beds is currently uncertain and the subject of debate — they appear to be either preceding or around the Late Jurassic/Early Cretaceous boundary (c. 140-120 mya).[1] The description was published in an issue of the journal Nature.[2]
