Mellita caroliniana inside a Dinocardium robustum
Echinoid Express posted a gallery image in Echinoids
From the album: My Echinoid Collection
Mellita caroliniana inside of a Dinocardium robustum Waccamaw Formation Early Pleistocene (~2.5 Ma) Columbus County, North Carolina, USA Self collected in November, 2023 This is my first "whole" echinoid of the Waccamaw formation, and my third North Carolina species found! This Mellita caroliniana was hiding inside of a matrix-filled Dinocardium robustum also known as the Atlantic Giant Cockle. I discovered it at the last moment before I probably would have accidentally destroyed it, though I was using a less aggressive cleaning method due to a drought in the area. There are a number of other mollusk species in the cockle as well, but I stopped attempting to extract them to keep the matrix stable. The aboral surface is crushed in and the petaloids are a little fractured due to this, with some very small surface pieces missing, but it is still a great specimen! It is currently sitting in a cabinet until I can figure out the best way to preserve it with consolidant, as I am worried it will fall apart if I am not careful. It is likely going to stay in this cockle as well, which I think makes for a good pairing, as well as a demonstration as to how things get buried together in the formation. There is another fragmented specimen in the shell as well, but likely not complete. There is no telling what else is buried in the matrix beneath the sand dollar that I may never unearth; there could be a whole other echinoid under there as far as I know!-

The shells shown below I excavated from the Barton Geological Beds from the Upper Eocene band. The one on the far left is a crasatellid, the shell to its right is a cockle, and the three shells on the far right are scaphopods, but beyond this I'm not sure what they are and guidance would be appreciated. Thanks in advance for any proposed IDs Othniel

I have never found pearls before so I am posting for confirmation. I have seen modern blister pearls at rock shows. Also wondering if these are fossil or modern day. The background for these finds is my wife had oysters locally and one had what we believe is a blister pearl. She seems to have an affinity for pearls as she has found 4 pearls (not blister)--2 in mussels and 2 in oysters. A few days later while walking the beach I found the large 1 1/2 inch pearl in a piece of quahog (Mercenaria) shell. Then I found other quahogs with interior coatings that differed from the normal shell. These had small raised bumps or "pimples". Then my wife found a cockel shell that had a small cluster of pearls. i wonder if these are possible Pliocene fossil pearls rather than recent? There are Miocene/Pliocene fossils shark teeth and fish material. Are these in fact blister pearls and how do I preserve them? Thanks for looking at these.First picture is modern oyster with blister pearl. Quahog blister pearl--fossil pearl?

Hi all, So the Cerastoderma genus has (in addition to a few other fossil species) two extant species: C. edule (common cockle0 and C. glaucum (lagoon cockle). Both of these species appear (both fossil and modern) here in the North Sea, and their Eemian fossils are common finds at the Zandmotor. Now I have always been told, and read in most of my books, that the difference between them is that: -> if you draw a vertical line from the umbo downwards, C. edule is pretty much symmetrical while C. glaucum will have one side more stretched out. As can be seen in the picture above. Pretty straightforward. Plus, this is what I explained in one of my old Instagram posts: But, while searching a bit around, I just now saw on the Wikipedia website a picture of a symmetrical cockle that they claim is C. glaucum. And WoRMS also has some pictures of some more or less symmetrical cockles for the lagoon cockle! So I am very confused... What is the difference then between the two species? Looking forward to your answers! Best regards, Max

This was carved carefully from a block of matrix that fell out of the cliffs into the bay. Of the dozens that I found, this was one of the few that did not completely fall apart what it was separated from the surrounding sand. Though thicker than many shells in the same chunk of sand, they are extremely soft in this location and incredibly fragile. Donated to the Delaware Museum of Natural History.

Avery nice double valve cockle. Single valves are not uncommon at this site but double valvers are very uncommon for this species.

A nice cockle found on the Zandmotor. Species: Cerastoderma edule. A very common species, not really worth picking up if you already have some.-
