6.7" Fossil Fish (Wendyichthys) Plate with Pos/Neg - Montana

 
 
 
This is a gorgeous specimen of Wendyichthys, a member of the actinopterygian (Rhadinichthyiformes) from the Bear Gulch limestone of Montana. The specimen has both its positive and negative sides of the rock for display. Specimens like this simply don't come up for sale very often.

Rhadinichthyids are characterized by the key-hole shaped notch in the snout that is framed by the rostro-postrostral and antorbital bones. The function of this notch is uncertain. This fossil has amazing color and preservation, with clearly defined thick, rhomboidal (Ganoid) scales called Palaeoniscoid type. This 220 million year old specimen is about as perfect a representative of this subclass. Paleozoic Actinopterygii were generally very small fish and are known predominantly from poorly preserved remains.

While Actinopterygians represented just 33% of fish species in the Bear Gulch beds, but today's ray-finned fish constitute 97% of all living fish species.
