Fossilized Glider Takes the Origin of Mammals Back to the Triassic

A new fossil specimen of Vilevolodon diplomylos, an ancient herbivore similar to a flying squirrel, may push the origin of mammals back millions of years earlier than previously thought.

Vilevolodon is a haramiyid, an ancient group of animals that lived during the mesozoic era. Until recently they were only known through a few fossilised teeth, but new finds are shedding more light on these enigmatic creatures.


This new specimen features a well preserved middle ear, revealing more advanced structures than had previously been seen. These ear bones could place haramiyids within mammals as a group – settling an argument between palaeontologists and pushing back the origin of mammals to the late Triassic.
