This amazing double valve specimen is a single oyster. It was found in the basal sands of the PeeDee Formation at a quarry in Southeastern North Carolina. These oysters are often found in association with Hardouinia mortonis and kellumi echinoids.

Donating My Beauty
I_gotta_rock posted a topic in Partners in Paleontology - Member Contributions to Science
When I found this baby in a lump of sand that had fallen out of the cliffs, it took my breath away! Even in museums, I had not seen an Isognomon shell so complete! I excavated it ever so carefully with an old toothbrush, trying hard not to flake the mica-like layers off of the clumbly shell. It's been the pride and joy of my collection. However, my collection is overtaking the house. So, after enjoying my pretty shell for several years, I decided to donate it to the Delaware Museum of Natural History, which prides itself on its extensive mollusk collection, both fossilized and modern. The museum's fossilized shells are all kept in storage, while the colorful, modern ones are out on public display next to the Dinosaur hall. Go figure. However, they are planning a new permanent display of fossil shells. Here's hoping that this gets viewed down the road! Meanwhile, someone at the museum thinks that although Maryland Isognomons have always been identified as I. maxilllata, based on an Italian holotype, they are probably their own species. This specimen is intact enough to try to describe that new species. I can't wait to hear what happens as he works on this project!

Although there are oysters littering the beach, I would hesitate to call any one of them anything other than modern. The fossilized oysters of this type retained their colors remarkably well. This shell was excavated from a lump of matrix deposited in the Chesapeake Bay after a landslide. This specimen was donated to the Delaware Museum of Natural History.

Hi all, I found this fossil oyster (Ostrea edulis) two days ago on the Zandmotor (Netherlands). It's from the Eemian stage of the Pleistocene (120'000 years old). What made me pick up this oyster was its really weird feature. In the inside, this looks like a normal oyster: But when you turn it around, you can see that this oyster had a really rough time! Part of it is completely crushed, pushed in. And there are weird lines on it too. Now of course, the first idea that came onto my mind was that this oyster got crushed when it got pumped out of the sea and thrown onto the beach. But this wouldn't really work, because if you apply just a bit of force anywhere on a fossil oyster, it will easily break/snap. It won't get a new shape. And I have no clue what might have made those weird lines on it. Therefore, I ask your opinion: what do you think happened to this oyster for it to become crushed (but not break), and have those weird lines? Looking forward to some interesting theories!

Last week while visiting Waco, Texas, I took four of my grandchildren to the Waco Research Pit. After getting a permit, we spent about three hours there and among the more fascinating fossils we found were oysters (possibly of the genus Texigryphaea). Of special interest were the epibionts, some of which seem to be parasitic. There were at least two sizes of tube worms, and bryozoans. The second picture below is not of epibionts on an oyster, but rather a one-inch wide piece I found separately in the same area. If I understand correctly, the Waco Pit is in the Del Rio Clay Formation, Cenomanian Stage, Cretaceous. It was a nice trip and a great place to take children. Russ

Hi All, I grew up on the east Side of Fort Worth, Tx. literally on the banks of a creek that flowed into the West Fork of the Trinity River. My Dad always said the period of the deposits were Cretceous and I became quite the young fossil hunter, finding many full ammonites, pet wood and of course lots of oyster shells. Literally 40 years ago, I dug up this complete oyster. To my delight, my Stepmom had kept it all these years and gave it to me just a few days ago. It's huge, 4 inches toe to edge. That's my wife's hand holding it - no photo tricks. Please can you give me full ID?

Self collected from a bluff along the Tar River upstream of Tarboro N.C. This is a fairly common oyster in this deposit, but most are extremely brittle and crumble upon touching. Still looking for my first complete (double valve) specimen.

This by far has been the most ambitious trip that I've done, but it was certainly worth the long drive times, poor truck stops (to sleep at), and lack of time to sleep and even eat. In just 10 days I traveled through 7 states (WY, ID, MT, CO, UT, AZ, NM) and covered at least 4700 miles (I might actually have broken 5000). Not only did I alot some time for general fossiling/rockhounding, but also time to stop at a few of the more "touristy" types of places (national parks/monuments, etc). The first day I visited a couple sites in southeastern Montana, with the first being known to produce oysters. It took longer than expected to find, but afterwards I discovered the site to be completely loaded with oysters and oyster fragments. The majority were completely covered with just a tiny bit showing, but after finding a few it seemed like all of them kept popping up one after another. Most were under 1cm in total length, but I found a couple that were larger. The next site was a little disappointing in that due to poor road conditions, I couldn't make it out to a few of the stops that were rumored to yield crinoid pieces (given that I've been working on crinoids for the past year at university, this was going to be one of the highlights of my trip for rockhounding). But I did manage to find one of the stops, which while it appears mostly picked over, did produce one nice piece of coral and several pieces with fragmented clams. This was actually a place that encompassed much more land than I anticipated, so I hope to return next year and alot several days there.

I was told this was a clam. Now, another person tells me it is an oyster. How do I tell the difference?

Looking for ID for the 3 different bryzoan specimens labeled 1, 2, and 3 as well as these ultra cool little oyster clumps. Location = Hampton VA USA There is an offshore fossil bed that these wash out of after storms down on a private beach I have access to. Miocene I assume, somewhere around the St.Mry's fmn. Also coming out of this bed are the less frequent poorly barnacle-encrusted chesapectan and the very very infrequent ecphora. I've found very infrequent fossil horse teeth 1/4 away so there is a lot going on fmn wise... I collect these when I'm local after storms and the oysters are pretty cool as they semi-frequently form the free-standing clumps of 2 to 4 or 5 oysters. I like to dump these into interesting glass containers as they make pretty cool display pieces. Anyway, also attached are a few more pics of the oysters and bryzoan specimen #2. Thanks in advance.

This beautiful little oyster was self collected. It was dug out of the formation with both valves, always a great way to find bivalves. Was originally assigned to genus, Conradostrea but is now Myrakeena. Lit: The Geology and Paleontology of the Lee Creek Mine, North Carolina, II. Clayton Ray, editor. LATE PLIOCENE AND EARLY PLEISTOCENE MOLLUSCA FROM THE JAMES CITY AND CHOWAN RIVER FORMATIONS AT THE LEE CREEK MINE, by Lauck W. Ward and Blake W. Blackwelder. Page 113

This was found in the spoils from dredging the C&D Canal in the 1980s. Recent removal of spoils sand for road construction in the area exposed previously- inaccessible layers of sand. It is currently one of the most common finds at the site.

This was found in the spoils from dredging the C&D Canal in the 1980s. Recent removal of spoils sand for road construction in the area exposed previously- inaccessible layers of sand. This species is not listed in the Delaware Geological Survey's bulletin about the fossils of the Canal. It is distinguished by its small size and non-plicate (no ridges) central area of the shell.

This was found in the spoils from dredging the C&D Canal in the 1980s. Recent removal of spoils sand for road construction in the area exposed previously- inaccessible layers of sand. Originally identified as Ostrea tecticosta. It remains in the same family. Being much less common than its cousin O. falcata, this species is not listed in the Delaware Geological Survey's bulletin about the fossils of the Canal. It is distinguished by its large attachment point.

Formerly known as Ostrea panda. It remains in the same Order. This species is not listed in the Delaware Geological Survey's bulletin about the fossils of the Canal. It is distinguished by its round shape. Pycnodontes are an extinct genus of oysters known as foam or honeycomb oysters.

Upper valve only. The genus of this has used several genera. Currently Peilinia is accepted (Kues, 1997) it has also been Ostrea and Lopha in several publications.

Hi, I was wondering if anyone had any thoughts on the ID of these fossil structures. They're found in a fossil patch reef of Bartonian age in Northern Spain, at the moment I am exploring the possibility that they could be very large oysters of some kind, they could possibly be stromatoporoid fossils though (however they don't have any obvious internal layering or structures). Other fossils nearby include small oysters and solitary and colonial scleractinian corals, along with large nummulitid foraminiferans. The layered fossils were very hard, and I was not able to take any samples, interestingly they did spark in contact with a hammer, could this be due to silicification? One of the nummulites also had a shiny metallic luster. Hope some of that helps, thanks in advance for any help.

I was in Monterrey mexico last summer and I was looking for fossils at cerro del las mitras. It's a mountain that is cretaceous in age. I think this fossil is either from the San felipe or mendez formation. The most unusual think is the green coloring!!!

Hi,could be on the left a oyster like spondylus,and on the right a clamshell? The right is about 5cm and the left is 4cm.
