ID Please On This Fossil Fish

[steelhead9]

I bought this on everyone's favorite auction site as a split nodule 13" long. I glued the 2 halves together and prepped it down from the top. The nodule is, I assume limestone, but is unlike any I have seen. It is very soft on the outside and gets very hard on the inside. The bone is very fragile and pink in color with a microscopic layer of black on top. As you can see by the front on photo, it was a very toothy little bugger. No collection info was available from the seller. My best guess is enchodus or some type of early shark, but that is just a shot in the dark. Help Please!

I think you can rule out early sharks. The spine seems to bony and not cartilaginous - so Actinopterygii and not Chondrichthyes. Enchodus would also be my wild guess.

Those vertebrae don't look like those of Enchodus to me.

Any ideas?

[LordTrilobite]

no I don't know what else it could be. but the vertebrae don't seem similar the ones I see from Morocco.

[oilshale]

Hmm, you are right - definitly not Enchodus vertebrae. No idea what they are, sorry!

I'm not sure what fish it is but it's a killer piece.

Turns out to be a flattened calamopleurus.
