Oligocene Fish Plate.

This is a recent eBay aquisition.

It's a multiple fish plate from Poland. Oligocene in age.

The fish represented here are Capros rhenanus .
Probably from the Carpathian Mountains.

I don't generally buy fossils, but these fish are fascinating to me.
There are 4 complete or nearly complete fish on this slab, with the parts of a few others, at least.
These fish were tiny, as you can see.

Right Click, and select "Large" for best viewing.
