Birbalomys

Birbalomys is an extinct genus of rodent from Asia.

The 30 centimetres (12 in) long creature has been thought to have been a member of the extant gundi family, but reconstructions of its physical appearance are highly speculative.[1] Some paleontologists[who?] consider Birbalomys to be the most primitive true rodent, related to the ancestors of all members of the order Rodentia.
