juvenile Priscacara Eocene Green River Wyoming USA

Nala,

not a Gosiutichthys but either a very nice Mioplosus labracoides Cope, 1877 or a Priscacara sp.. Gosiutichthys has only one dorsal fin, Mioplosus and Priscacara two. Mioplosus has relatively soft 1st dorsal fin rays whereas Priscacara has more sturdy and thicker fin rays.

Thanks Thomas,for your expertise the name was given to me and i had no reason to doubt!could it be a juvenil?

My pleasure. It could be a juvenile Priscacara. The first dorsal fin seems to have spines.

Thanks a lot Thomas

nice preparation on all your fish. I have several fish from the Green river formation that I would like to prepare but I'm new and very inexperienced. Can you give me some helpful information to get me started. I do have a compressor but no tools other than some denial picks from my dentists. i have a very nice Priscacara, maybe 10 inches long that is in some heavy matrices. Thanks in advance

Hello bowfin,if i could i would be glad to help but i had my green river fishes by exchange(i'm a french collector)and i never did prep these fossils,best regards
