bat bone

[Napoleon North]

Hi

 

Is this bat bone?

Is this fossil?

Location: Twardovski Cave , Kraków , Southern Poland

It looks modern to me. I’d be interested to see if it is a bat bone

Just happen to have these modern bat (humeri ?) as examples. I think it's Brown bats that we have around here.

Perhaps it is of a different rodent of sorts. Rat, squirrel, really tiny cave bear.

Actually they are in a boat shaped piece of layered concretion that has some neet little brachiopods included in the layer.

Whole skeleton. Some arthropods fleshed them out from the bat mummy I had. 

Hey, you never know when you might need something like this.

There are some nice high res images of Pleistocene bat humeri to compare to, in Gunnell, Gregg F et al. 2015. Bats (Chiroptera) from Olduvai Gorge, Early Pleistocene, Bed I (Tanzania). American Museum novitates; no. 3846, pp. 35.
