Bone guy Posted February 3, 2018 Share Posted February 3, 2018 So I was picking at the back of my new diplomystus and I found a partial skeleton! It's majorly cut-off, I know, and it's nothing special. I just figured you guys might have fun figuring out what it is! Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 3, 2018 Share Posted February 3, 2018 It's amazing what one can find while fiddling. Is it from The Green River Formation and how long is the specimen? Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
Bone guy Posted February 3, 2018 Author Share Posted February 3, 2018 Yeah it's green river, length is about 1.5 inches. Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted February 3, 2018 Share Posted February 3, 2018 There are very clever people who know their stuff on the forum but I'm not sure they could be certain from what is left of this. But I do know that the most common smaller fish found in the same beds as Diplomystus is Knightia sp., I even used to have one, very common fish on the fossil market. So that may be a likely candidate, though I am certainly not saying it is one and will probably be shot down in flames at any moment. But you did ask for guesses, so this is one. Life's Good!

Miocene_Mason Posted February 3, 2018 Share Posted February 3, 2018 It’s in too poor of a state for me to ascertain. Based on size, probably a knightia. Could be a Gosiutichthys as well. “...whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been and are being evolved.” ~ Charles Darwin Happy hunting, Mason Link to comment Share on other sites More sharing options...
RJB Posted February 3, 2018 Share Posted February 3, 2018 Diplomystus. Just a guess, but from the look at those bones on the bottom right hand side, the part that dips downward, tells me its a diplomystus. RB 2 Link to comment Share on other sites More sharing options...
Bone guy Posted February 3, 2018 Author Share Posted February 3, 2018 Cool! Yeah my guess was diplomystus. Still pretty cool though, gonna treasure these fish for a long time. Link to comment Share on other sites More sharing options...
Rockwood Posted February 3, 2018 Share Posted February 3, 2018 Would there be a chance of exposing some fins on the ventral side ? Seems like I remember them as being diagnostic in some cases. Link to comment Share on other sites More sharing options...
Rockwood Posted February 3, 2018 Share Posted February 3, 2018 Found it. If you can find a complete enough anal fin that should differentiate Knightia from Diplo. at least. Link to comment Share on other sites More sharing options...
