Lobe-fin, Lobe-finned. Fish.

Gyroptychius is sometimes referred to as a “lungfish” but it is actually a genus in the extinct family Osteolepidae, which is closer to the ancestry of amphibians than lungfishes.  It’s a lesser-known relative of Osteolepis which is also known from the same beds.

A great piece for the collector looking for something not too far from the lineage that led to early tetrapods, our own distant ancestors
