JohnJ Posted February 5, 2016 Share Posted February 5, 2016 Given it's size, it is an Exogyra valve shell. They are commonly found in the Austin, Texas area. The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Guguita2104 Posted February 5, 2016 Share Posted February 5, 2016 Gryphaeidae bivalve valve. Link to comment Share on other sites More sharing options...
DPS Ammonite Posted February 5, 2016 Share Posted February 5, 2016 This is the small upper valve of an exogyra that the animal could lift up. The lower valve is much more massive and has a convex exterior. My goal is to leave no stone or fossil unturned.
