Green River fish - what do we have here?


Recommended Posts


I got this fish with some others in a trade deal the other day; I was supposed to get a mixed box of Diplomystus and Knightia, but this guy stood out for me. Doesn't look like either, and seems a bit too big for Amphiplaga. Maybe juvenile Mioplosus? Anybody? Is there another photo that can help? Thanks for looking!

I think it's an Amphiplaga brachypterus

Mioplosus labricoides  would have two dorsal fins. 


Here is my Amphiplaga




And a comparison from Grande's 1984 Bulletin 63 "Paleontology of the Green River Formation, with a Review of the Fish Fauna".
