emmag15 Posted February 22, 2019 Share Posted February 22, 2019 I'm studying fossils and I'm having a difficult time understanding the visual(and structural) differences between Exogyra and Gryphaea. Any insights would be very much appreciated! Link to comment Share on other sites More sharing options...
Fossildude19 Posted February 22, 2019 Share Posted February 22, 2019 Not sure if you came across this at all. This PDF may help as well. 4 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 IPFOTM -- MAY - 2024 _________________________________________________________________________________ "In every walk with nature one receives far more than he seeks."

erose Posted February 25, 2019 Share Posted February 25, 2019 Without using pictures i would say that in Gryphaea the lower, or larger, shell curves back up over the hinge point. In Exogyra the shell coils like a snail down and away from the hinge. 1 Link to comment Share on other sites More sharing options...
