Jazfossilator Posted April 16, 2018 Share Posted April 16, 2018 last night there were heavy thunderstorms in Myrtle beach so I figured some good stuff would get churned up and deposited on the beach, I braved the brutal wind and cold early this morning and it payed off, I found these 2 fossilized echinoids within 20 yards of each other, any more specific info would be great!the top of the first is missing, and I know the second one is in real bad shape and a positive ID is unlikely.

Plax Posted April 16, 2018 Share Posted April 16, 2018 named for the Sabiston Farm up your way as I recall. Kier has two related species in Florida and have always felt that we could distinguish them here (Carolinas) as well. Not sure the species is valid for the ones we get in the Waccamaw and Goose Creek but have always called it that. I believe that DuBar listed it.

FossilDAWG Posted April 16, 2018 Share Posted April 16, 2018 For clarification, are we talking about the same ID for both specimens? They look different to me, though that might be because of the wear on the 2nd specimen. Don 1 Link to comment Share on other sites More sharing options...
sixgill pete Posted April 16, 2018 Share Posted April 16, 2018 To me the first one looks like Hardouinia mortonis, the second Rhycholampas sabistonensis. The first is Cretaceous the second Pliocene / Pleistocene. 3 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...

There's a chance that either of them could be something else including Agassizia for the second one and Hardouinea mortonis (giant Brunswick County NC form) for the first one. If I had them in hand I'd be sure. Most likely ID is still Rhyncholampas sabistonensis but that is based on what is commonly found there in the Waccamaw and Goose Creek formations. There's plenty of Peedee in the re-nourishment of those beaches of course. 2 Link to comment Share on other sites More sharing options...

Jazfossilator Posted April 16, 2018 Author Share Posted April 16, 2018 Thanks for all the suggestions guys I'll do my best to identify them properly, they are the first echinoids I've ever found so I have some research to catch up on! Link to comment Share on other sites More sharing options...
Jazfossilator Posted April 17, 2018 Author Share Posted April 17, 2018 I am now Really thinking that the first is Hardouinea mortonis after seeing this example 1 Link to comment Share on other sites More sharing options...
