fifbrindacier Posted January 2, 2017 Share Posted January 2, 2017 I agree with that ID, the one in the middle might be of an heteromorph because it is a little curved.

Fossildude19 Posted January 2, 2017 Share Posted January 2, 2017 Cropped and Brightened the pic: More angles would be helpful to determine other possible identifying characteristics.

abyssunder Posted January 2, 2017 Share Posted January 2, 2017 The middle one looks to be a radiolitid rudist lower valve, the other two could be requieniid rudists, like Toucasia , all present in the Cretaceous of Istria,Croatia. Jean-Pierre MASSE et al. 2004. Lower Aptian Rudist Faunas (Bivalvia, Hippuritoidea) from Croatia. Geologia Croatica 57/2, p.117–137.

FossilDAWG Posted January 2, 2017 Share Posted January 2, 2017 My initial reaction was also that they all could be cephalopods, the middle one a heteromorph such as Glyptoxoceras. However a closer look did not offer any suggestion of suture lines, and the "ribs" on the middle specimen have a sort of irregular fluting or folding aligned with the long axis of the specimen that would be atypical for an ammonite. I am inclined to agree that they may be rudists rather than cephalopods. Don Link to comment Share on other sites More sharing options...
JohnJ Posted January 2, 2017 Share Posted January 2, 2017 I agree with abyssunder and Don, these are rudists. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

bone2stone Posted January 5, 2017 Share Posted January 5, 2017 Knee jerk reaction, it was just first thought. Then you guys came up with some better input. I agree with conclusion. Looks as if Brus was on the right track all along....... I personally have not seen any rudists like these, bottom or top. I think I need to get outside of Texas more often.
