DPS Ammonite Posted January 27, 2016 Share Posted January 27, 2016 (edited) The right photo looks like the upper valve of a Texigryphea or Pychnodonte similar to ones found in the Cretaceous Austin Chalk in the Dallas area. Please show us the other sides of both pieces. Edited January 27, 2016 by DPS Ammonite 1 My goal is to leave no stone or fossil unturned.

JohnJ Posted January 27, 2016 Share Posted January 27, 2016 Looks like a burrow cast and the upper valve of an Exogyra. 2 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

JohnJ Posted January 28, 2016 Share Posted January 28, 2016 Definitely an Exogyra valve. On the burrow-looking thing, am I seeing blurred suture lines? You may have a partial Baculites, instead.

BobWill Posted January 28, 2016 Share Posted January 28, 2016 (edited) Yep the Exogyra right valve shows the muscle attachment scar on the inside and the growth lines outside. When you find the left valve it will be much thicker and convex on the outside where the growth lines are but concave and with a similar scar inside. Showing something for scale would verify which oyster it is. Edited January 28, 2016 by BobWill 1 Link to comment Share on other sites More sharing options...
Guguita2104 Posted January 28, 2016 Share Posted January 28, 2016 IMO, it's Pycnodonte or Exogyra, bivalves of Gryphaeidae family . Link to comment Share on other sites More sharing options...
