Diplomystus poweri from Hajoula lebanon and Cretaceous in age

Of course, I have only ever touched Diplomystus dentatus  from the Green River Formation, Eocene. The head of your critter looks like a familiar diplo, but obviously, "shorter" and deeper bodied for its size. These traits to my eye are so exaggerated that it makes me question the legitimacy of the specimen. In addition, the spine of the dorsal fin looks preternaturally long for the total size of the critter. But having no experience of fish from that location or age; I will have to wait for those of experience to educate me.  Perhaps a short, fat, big-headed diplo was the norm for that time/locale.

 

Edit: I searched for "D. poweri". The  displayed images of the fish from Lebanon did not look all that different from diplos of Green River. I believe your piece is an artistic endeavor.

Worry none my friend.  In a couple of days I will take this specimen and give it the 'once over' with my #10 opti-visor,  then I will be able to see EXACTLY what is going on.

You have charted the very best course of action. That approach will show any mischief. I hope I am mistaken about the nature of the piece.

The name is the issue!  ;) 

It should be labeled Diplomystus birdi

 

Ron's example is quite nice, by comparison.

It's adorable how short and stout those fish are.

Excellent, that helps! The pictured specimen even has a remnant of the long dorsal, as well as the unexpected, short and fat physiognomy. Thanks.

I was stymied when I searched the first name, as you did. Like you said, ... all that did was bring up Diplomystus dentatus images. 

I knew there was a different species from Lebanon. Just didn't know what the name was.  Luckily, I found it easily at Expo-Hakel.  :) 

Thanks for making me dig a bit deeper.

As Tim pointed out, Diplomystus birdi is the only valid species from Lebanon:

 

Forey, P.L., Yi, L., Patterson, C., & Davies, C.E. 2003

Fossil fishes from the Cenomanian (Upper Cretaceous) of Namoura, Lebanon.

Journal of Systematic Palaeontology, 1(4):227-330
