Paleocene??!!

As far as I know, Australia's oldest described bat (_Australonycteris 
clarkae_) is of Eocene age (c.55 MYA).  Still very impressive.  
(Incidentally, based on the structure of a preserved ear bone (periotic), 
_Australonycteris_ is thought to have been capable of echolocation.)

The full reference is:

Suzanne Hand, Michael Novacek, Henk Godthelp, and Michael Archer (1994).  
First Eocene bat from Australia.  Journal of Vertebrate Paleontology. 
14(3):375-381.

This paper also questions the chiropteran identity of the North American 
_Wyonycteris chalix_, of Paleocene age.

Hopefully it won't come to that.
