FossilDAWG Posted February 22, 2020 Share Posted February 22, 2020 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 7 Link to comment Share on other sites More sharing options...

jpc Posted February 22, 2020 Share Posted February 22, 2020 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? 2 Link to comment Share on other sites More sharing options...
MB Posted February 22, 2020 Share Posted February 22, 2020 I think this is a Ferroranina dichrous with an incomplete front. Surely from the Britton Fm. (turonian) of Texas. 4 http://www.mbfossilcrabs.com/ Link to comment Share on other sites More sharing options...

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? Link to comment Share on other sites More sharing options...

Ruger9a Posted February 23, 2020 Author Share Posted February 23, 2020 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. Link to comment Share on other sites More sharing options...

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. 1 Link to comment Share on other sites More sharing options...
