Mari Posted July 14, 2022 Share Posted July 14, 2022 Hello Everyone. My grandaughter is in 4-H Geology and we found this specimen in Southwest Kansas. We have no idea what it is or how to label it for her exhibit box. Any help you could give us would be greatly appreciated. Thank you! Link to comment Share on other sites More sharing options...

IsaacTheFossilMan Posted July 15, 2022 Share Posted July 15, 2022 Perhaps fragment of Gryphaea mucronata, known from the Cret. of Texas through Kansas. I see some places on the internet referencing it as Texigryphaea mucronata, but I cannot see some form of consensus - GBIF lists it as G. mucronata, so I'm going with that!

JohnJ Posted July 15, 2022 Share Posted July 15, 2022 This is most likely to be a fragment of a Pennsylvanian aged Myalina species bivalve. The second photo shows the distinctive pattern of the hinge interior. 2 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

Here is great shot of the very distinctive underside of the hinge from an inactive Forum member. http://inyo2.coffeecup.com/kansasfossils/pelecypods6.html Edited July 16, 2022 by DPS Ammonite My goal is to leave no stone or fossil unturned.
