Can anyone verify my analysis (?) of this specimen?  It was part of a unidentified lot sale.

Yes, a lobster cephalothorax, I think.

Thank you!  Any idea of the species?

Not a clue, I'm afraid. :shrug:

Try Rodney Feldman. Maybe he would know.

Love the emoji!!!  It may be too degraded to be able for anyone to identify, but I won't give up hope.

Thank you.  Is he a member of TFF?

Better ask Rodney, because Marty hasn't a clue!

No. But he is the worldwide expert on Decapoda. See Piranha's post above. He beat me to it.

Thank you guys...….  Maybe Rodney (the Geologist) can help with the specifics.

I'm sure he is a great geologist, but his primary research has always focused on crustacean paleontology.

These are not lobsters.  They are raninoidid or possibly paleocorystid crabs (Raninoidea or Paleocorystoidea).  See MB Fossil Crab's web pages here and here for some examples.

Don, I was thinking the same thing when I first saw them, but I don't like getting out of my comfort zone.  :shakehead:

I see definite crustacean texture on this.  If you do send Feldman or anyone else photos, you ought to try to get better shots; more in focus.  People send me photos to ID often enough, and my reaction is that if they can't take the time to get a nice fosused photo, what makes them think I have the time to decipher them?

I think this is a Ferroranina dichrous with an incomplete front. Surely from the Britton Fm. (turonian) of Texas.

JPC,   Ouch, I've already sent Mr. Feldmann these photos.  Thanks for the recommendation, they actually looked clearer before I cropped them.  Do you think I should try a different camera and send him updated photos or just wait to see if he responds first?

Thank you guys!  I will check these out.

JPC, I am still thinking along with you on this as it still looks like a crustacean to me.  I hope these are better photos.  They are top, left, right, rear, bottom, bottom2 and front bottom up.

OMG, thank you guys!  My eyes kept seeing a lobster, how little I know.  Dr. Feldmann just confirmed your analysis.  Quote  "Wayne. It is not a lobster, it is a raninid crab, Cretacoranin testacea. I am attaching a paper in which it is illustrated. It is really a very nice specimen. "  I tried to attach his paper but I can't for some reason, sorry.  Thank you all for taking the time to assist in the identification of this fossil.
