Hello! I found this item in the mouth of a creek that empties into The Great South Bay on L.I. The creek has been used by Indigenous Peoples before European settlers arrived circa 1720. Is this a petrified oyster? I can’t tell for sure, but I feel the dark/gray/silver area is what’s left of the calcium? Any help would be greatly appreciated!

Went hunting yesterday. Initially found very little. One very nice G. cuvier tooth. SO , I started moving checking out places that had produced in the past. One place had whale vert eroding out of the bank into the stream a couple of years back. So, I went there and Lo and Behold, a whale vert laying in the water directly below that bank. Hunting for fossils is sometimes easy. The bank is hard, almost rock like clay and there are hundreds of shells on the face of the bank. Small oysters and pecten's dominate. I noticed a very large oyster that seemed to have become calcified or silicified that had also fell out of the bank. I have taken some photos... The Whale Vert The Oyster Here is a pecten from the same location.... I always search the Internet for possible matches, For the Pecten I found a paper written by Richard Hulbert and Roger Portell who lead their respective departments (Vert, InVert) at the University of Florida. It had this Picture of Florida Pliocene Pecten's I did a side by side of the pecten I found. I am now thinking I have found Carolinapecten murdockensis druidwilsoni , but think I need someone like @MikeR to validate. Continuing, I searched the Internet " giant oyster Florida Pliocene" and found... this newspaper article, I wonder if this very large oyster I found is Qstrea Coxi from the Pliocene of Florida. Maybe @Boesse can tell me. So, if the Pecten and Qyster turn out to be Pliocene species, is it reasonable to think that the Whale vert might be from a Pliocene whale ? and any this was just the 2nd spot I tried...

Hi everyone, Recently found this oyster shell specimen from an area near Tampa FL amongst dredged limestone where I’ve found agatized coral. 99% sure it’s fossilized (has a very small amount of limestone stuck to the bottom), but something interesting is that there appears to be botryoidal agate coating it. Is this an agatized oyster? Is this a common find around tampa? And can I bleach it to remove algae?

Hello, This is probably not the right forum but I am not sure where to ask. I have found these shells in northern Italy. I don't know if they are fossils because they look modern, color wise and everything. But there is something strange, it's not just the outer shells, the inside of them are also filled. I don't know if it will be clear in photos, but it almost looks like their meat to me. I thought meat can't be preserved? It is rock hard and they also feel like rocks and I believe there is also a little bit of matrix involved. Is this some preservation thing that I am not aware about? They are still somewhat purple, like the modern ones I see everywhere here. Any explanation and further info is helpful as I know people on this forum are very knowledgeable! And I really hope my amateur posts are not too annoying! Thank you.

These were all found in a dirt piles from an old homestead/ranch in a Mico/San Geronimo, Texas, creek bed we are excavating. It appears I have a chicken leg and oyster at least haha.

Hi All, Had some time off from work this past Friday, and decided to take a drive out to Big Brook to do some hunting. Had a pretty successful outing, finding some of the biggest shark teeth (Goblin) I've found in my handful of visits to the Brook. Would have been very happy to leave with just those few pieces. The best find of the day was a piece of a Mastodon tooth. I'm still learning, and at first didn't realize what I had, thinking it may be part of a turtle scute (still new to all of this). Thanks to a couple members of the "Fossils and Native American Artifacts (NJ and surrounding areas)" Facebook group, they were able to pin an ID. Compared it to some photos of other examples and it definitley looks like Mastodon. Totally blown away by this find!! Had a few other nice pieces photgraphed below. Last piece of the day was what appears to be a rib bone. Could very well be modern White Tail Deer, as the brook is rich an iron, and can stain the bone pretty quickly. I found the Goblin Shark teeth in the same deposit, but also found a partial of a more modern deer jaw. Jaw was partially white and brown (didn't save as I could tell it was modern). In any case, not sure if it's anything but a modern deer rib. Feedback good or bad is appreciated. Thanks! Calm day @ the Brook. Couple sifts in, and pulled this tooth. Good start!

It’s been a while, but now I’ve got something worth posting about that I’d like identified. :) Took a trip to Lake Texoma yesterday and my husband found this. My guess is some kind of bivalve, but I’m hoping that someone here has a little more knowledge.

Hello I found these near a river in Germany. In the state North Rhein Westphalia in the High Sauerland District. At first I was sure they were Chert nodules, but while examining the larger piece, it looks as if it is two halves. I am thinking now that they are both Chalcedony. Translucent with no bands. The bigger piece is the more interesting piece. It is palm size. The small piece If they are fossils, my best guess is oysters. Thanks.

A day with interesting finds. The water level has dropped from Friday, but the current is faster. Still Pea Soup. The Peace river is noted for being a mix of Miocene to Modern...on some days more then others. Out primary shark tooth finds were Hemipristis and G. mayumbrensis, both Miocene species. Have found Dugong verts, Rhino teeth fragments, small horse fragments, but also these... A silicified shell.. I frequently guess wrong... Oyster ? Thi 2nd set of photos is the UF MNH Ostrea_compressirostra-UF120412, a much larger Pliocene shell. Also found what is likely a deer tine. Look at those bite marks...must have been hungry. Finally, a fossil that looks like an Equus Navicular,, but slightly different. Note the fine grained detail.. Did not face much water erosion... Enjoy, Jack

Just to show: it is possible to find fossil pearls. This three come from the campanian of Hannover. They are found in a layer together with a lot of Oysters, all Ostrea semiplana So, when you find Oysters in a bed, look for small balls, might be a pearl This ones are right for a paper we write, will be published end of the years. If someone has pearls from upper cretaceous, let me know, perhaps we can add it not necessary to be campanian age, but upper cretaceous or tertiary, please

This was found in a dry portion of creekbed where Devonian age bedrock is out cropped (Lime Creek formation, Mason City, IA). The fossiliferous layers contain bryozoans, stromatoporids, brachiopods, crinoids. After using a tooth brush to rid it of the loosest matrix, this is how it looks. I've attached some microscope pics of the specimen as well. It's essentially a specialized webcam connected via USB to a computer. I'm not able to definitively discern what this is. I'm hoping it's a crinoid calyx but the closest resemblance seems to be some species of oyster. Any suggestions as to what exactly this is would be most welcome.
