jkfoam Posted June 17, 2011 Share Posted June 17, 2011 DLB, It would really help in identification if the gastropods were pictured with their aperatures exposes so we could see them. Folds on the columella or dentation on the aperature lips or if there is an umbilicus, etc, helps ID genus. Also, location, age and formation is always helpful information if it is known. JKFoam The Eocene is my favorite Link to comment Share on other sites More sharing options...

MOROPUS Posted June 17, 2011 Share Posted June 17, 2011 In my opinion, there are two mixed fossil layers. In th first row, just in the middle, the shell looks like Galeoda sp.(caenozoic era). The first fossil from the left, in the same row, is a Exogyra sp. (typical cretaceous fossil; the preservation is different). There are two moonsnails just in the middle of the pic, and something very similar to two Aturia sp. just in the bottom (both Caenozoic). Far to the left, a Dentalium sp.(could be Mesozoic or Caenozoic). A view from the other side of the shells will be desirable for further id's Link to comment Share on other sites More sharing options...
