historianmichael Posted September 14, 2021 Share Posted September 14, 2021 (edited) A couple of weeks ago now I stumped upon several outcrops of the Early Pleistocene Waccamaw Formation in South Carolina. I have been able to identify the various mollusk that I found except for these last three gastropods. Either the resources I have found don't include an example that matches these specimens or it was just too close of a call. I would love to get some opinions on what these might be. Any help would be greatly appreciated. Thank you so much! #1- Petaloconchus sculpturatus? #2- Ilynassa sexdentata? #3- Phrontis sp.?

MikeR Posted September 14, 2021 Share Posted September 14, 2021 (edited) #1 looks closer to Vermicularia #2 appears to be correct #3 looks like Nassarius bidentata, but I don't know if it made it out of the Late Pliocene. Julia Gardner's USGS Professional Paper 199 could help with Nassariidae.

historianmichael Posted September 14, 2021 Author Share Posted September 14, 2021 (edited) Thank you so much @MikeR! Based on Julia Gardner's publication, the third one looks a little bit like Nassarius consenoides. What do you think?

MikeR Posted September 15, 2021 Share Posted September 15, 2021 N. consenoides has incised lines that yours does not. Look at N. neogenesis.

That is certainly a possibility. It tough to work with the specimen at such a small scale and it is a little beaten up.
