Catfish fossil - Astephus antiquus.

Recent acquisition of mis-identified fossil fish. 

Listed as Knightia eocaena,  I knew the head was the wrong shape. A closer look revealed pectoral spines, and a dorsal spine.

I knew then that it was a juvenile catfish. 

This is most likely an Astephus antiquus.

Green River Formation.

Length  1- 3/4 inches.

Nice! :wub: I had then same experience, a catfish misidentified as a Knightia.  Yours is better, though as mine lacks the tail.

Really nice catfish - very good catch! I'm guessing it's an Astephus. To my knowledge Hypsidoris only occurs in the area around Farson and there the matrix looks different.

This one is pretty tiny.

A bit more than 4 cm in length. (1.5 inches, roughly)
