Polyipnus sobnioviensis
Fish
Oligocene
Carpathian Basin, Sobniow, Poland

30mm deepwater fish on 60mm slab.

Polyipnus is a genus of marine hatchetfish of the Family Sternopthychidae.  This specimen may represent the earliest occurrence of the genus which still lives today.

We used to have a number of specimens and they sold faster than we thought they would. It’s an oddball fish you’re not going to find in the Green River so it’s popular with collectors.
