ahlung62 Posted November 8, 2019 Share Posted November 8, 2019 I just acquired a GRF fish plate with a Knightia, two Diplomystus, and an interesting ventrally compressed (?) fish. Any help with identifying this fish would be greatly appreciated. Thanks in advance. Link to comment Share on other sites More sharing options...
Fossildude19 Posted November 8, 2019 Share Posted November 8, 2019 What is the size of the fish?

snolly50 Posted November 8, 2019 Share Posted November 8, 2019 It's pretty distorted, so just a guess. Consider Hypsidoris. The appearance of the tail and seemingly large-sized head suggest this ID to me. Tim just posted about size while I two finger typed. Yes, that info would help the ID efforts. Hypsidoris is a Lake Gosiute critter, so collection location would also be important. Another catfish, found in all Green River locales is Astephus, also consider. Human beings, who are almost unique in having the ability to learn from the experience of others, also are remarkable for their apparent disinclination to do so. - Douglas Adams, Last Chance to See Link to comment Share on other sites More sharing options...
FossilDAWG Posted November 8, 2019 Share Posted November 8, 2019 I was thinking the same thing, a catfish. However I don't see the pectoral fin spines, which should be prominent. Maybe they are still buried in the matrix. Don Link to comment Share on other sites More sharing options...

The spines are very robust in that image. The appearance of the skull and tail however, look like the critter above.

ahlung62 Posted November 8, 2019 Author Share Posted November 8, 2019 (edited) The fish is about 4.5 in long and is on a matrix that more closely resemble material from the split-fish area of Fossil Lake rather than Lake Gosiute (Farson?). Unfortunately, the plate did not come with any information regarding its origin. My first thought was also a catfish, but upon close examination, there seems to be scales along the body. That and the apparent lack of pectoral fin spines totally stumped me. Edited November 8, 2019 by ahlung62 Link to comment Share on other sites More sharing options...
