Are the hemipatagus Riverbend formation ? If so, wouldnt they be marieta carolinensis?

They were renamed a few years ago. Have to dig out the reference. Word came from Adam Osborn. Also Gagaria mossomi are now Thylechinus mossomi.

Nice trip pics. That clam is a beauty with all the colors.

I was going for echinoids too. Then in the bottom right of the pic it almost looked a little like 2 more Psammechinus carolinensis. The one thing I occasionally dislike about my in situ pics is that I’ll see a fossil that got away without me noticing it while I was taking a pic of the other one. It usually happens with the really small fossils.

Kim, the layer that the Hemipatagus come out of ( upper River Bend) does not contain the small Psammechinus echinoids; they come out of the sandy lower River Bend. There is also a really small irregular echinoid that comes out of the sand, Echinocymus wilsoni. It ranges from about .5 (point 5) millimeter to about 5 mm. We call them rice crispies. The Psammechinus are known as cheerios. 

 

I often look at in situ pics I take and see things I missed also.

Excellent finds Don, love the cow shark :fistbump:

Thanks Jeff. Cow Shark teeth are fairly rare everywhere, but in the Belgrade they are extremely rare. I was thrilled with the find.

Here are some more pics of the Hemipatagus carolinensis (was Maretia as @Hipockets said) I found 4 total, but the 2 in the previous pic were right next to each other. Takes a keen eye to see them as they are almost always fully sediment covered. They take a long time to weather out and clean up. mechanical prepping usually destroys them.

A couple years ago when these were washing up on Topsail, Linda kept referring to these as Hemipatagus carolinensis instead of Maretia carolinensis. I tried to find a publication at the time but couldn't. A few minutes ago I did another Google search and found a 2007 paper titled "Hemipatagus, A Misinterpreted Loveniid (Echinodermata:Echinoidea). Journal of Systematic Palaeontology 5 (2).

 

The publication states which echinoids should be moved into the genus Hemipatagus and includes Maretia carolinensis.

Thanks for posting that reference Eric. I had been trying to locate it without any luck. From rereading it, should not Maretia subrostrata from the Castle Hayne also now be Hemipatagus?

Nice. I was unaware they were found in the Oligocene deposits there.

For subrostrata, it says the outline, tubercles and shape of petals suggest the attribution to Hemipatagus. When first described by Clark in 1915, he put it in the genus Hemipatagus and Cooke moved it to Maretia in 1959.

So do you just leave them outside? I posted the “Echinoid Jackpot” post and the test of  every single one of them is damaged or partly missing in some cases. I don’t have any that large so I’m happy to have them, but I’m afraid to try to clean them up because I think they’ll fall apart if I do. There isn’t as much to clean as yours there. I don’t think mine would stand up to weathering, but maybe some of the others I have would.

Thats correct, I just leave them out in the weather on one of my tables. Sometimes it takes a year or more. I do wash them off with a soft brush to start with. This is very soft sandy matrix, not rock or clay.
