What type of mollusk is this? Oyster? Bivalve?Internal mold. Silurian Thanks for any help.

Duck Creek oyster ID please. This was the only one found in this area. I found numerous other early Cretaceous bivalves in Lake Texoma like Amphidonte walkeri, Graphea, Neithea.

Nice Gryphaea and exogyra oysters..very large ..biggest is 5.5 inches -
I found this oyster fossil in a creek bed on a walk with my son in Austin, Texas sometime in May 2020. I believe it was in a Quaternary geologic formation. I’ve collected a number of these, but never with a pearl. Just curious if anyone else has seen one!

Hey everyone, Someone on reddit posted this great-looking oyster, asking for ID. And I can’t figure it out. The hinge looks really weird to me and inconsistent with the usual Ostrea oysters I see... They said it was excavated from a construction site about 12 years ago in the city of Wroclaw (Poland), near the Odra/Oder River. Which means there isn’t any literature about the age/formation/etc. Only thing I could find is this geological map that puts the area in Tertiary sediments (which is logical but not very helpful). Anyone have an idea of what to say about this shell? Age and formation would be great, and genus (or species but I’m not getting my hopes up that high) also. Maybe @Kasia you’ve come across some of them? Thanks in advance! Max

Hey everyone! I recently acquired this oyster from Tulear province, Madagascar. The seller has listed it as Rastellum carinatum, but doing any research online, I’ve only found other sellers selling similar fossils. I did come across a Wikipedia article for Agerostrea sp. It appears to be the same shell, and it lists it as occurring in rocks that are Maastrichtian age from Madagascar. Are these the same species just under different names or are they separate? If so, what genus does my specimen belong too? Any response would be greatly appreciated from you guys, we’ll see how challenging this might be to figure out. Thanks again -Nick

From the album: Fossil Flourescence
In the daylight, this is an articulated Exogyra shell from the Cretaceous New Egypt Formation as it runs through Mullica Hill, New Jersey. I brought it home because it had an interesting bit of vivianite replacement covering half the surface of one valve. When I brought it home, I noticed some white material inside the shell cavity. I figured it might be calcite, which sometimes fluoresces. So, I pulled out my UV lamp. To my shock, not only did the white material glow an interesting powder blue color, but the majority of the one valve glows an intense, bright red! Meanwhile, the other valve doesn't glow at all. -

Scroll right to see what it looked like in the dark with the UV lamp. -
Can anyone help with a more specific ID on this oyster shell?
-
All of these were found beach combing in Charleston, SC and all were caked with what I believe is limestone. A. Not sure on this one. Thought clam before pulling away some limestone but now thinking oyster? About 5cm wide. B. Scallops, wondering type and age if identifiable About 3 cm tall. C. Was thinking scallop on this one but it doesn’t seem to have the same vertical lines, they’re all horizontal. Roughly 9cm tall. Thank you all in advance! I’ll be posting some corals and bones tomorrow if I have no luck finding anything myself

Here's another find I came across a while ago which looks to me like an intact oyster that has fossilized but I'm not sure on this. It almost looks like granite, but the shape is exactly the size of a small oyster - it seems to have some flakiness to it as well on the sides. Any thoughts on this? I tried to photograph all sides. If this was fossilized, any idea how old this would be?

A second large Clam or Oyster? I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer so that I could actually pick pieces up. After the heat this weekend, they were easy to pick apart once I got them home. Yesterday, I found the first piece. This is the one I found today. When it came out of the rock I was a bit shocked at how large it was. I carefully tapped around the specimen and was able to remove most of the surrounding rock carefully. This is the larger of the two pieces I found this weekend. I have less confidence in identifying it as has less features than the first piece. You can see shell material flaking off in the 3rd and 4th photos below. The fossil after I found it: Then, once I removed it from the rock:

I love and hate finding large fossils. They are really interesting and striking to look at, but I have a hard time getting an ID on them. I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer. After the heat this weekend, they were easy to pick apart. Yesterday, out popped this piece. There is another one I found today that I will be posting after this one. This piece has several wavy ridges. The shell material looks pearly, and perhaps some calcite replacement has happened. There was a piece of shell stuck on the mold portion as well. I'm seeing about 6 distinct ridges. Anyone know what it might be? Before I removed it from the rock: Several views after removing, trying to show the ridges:

Hi everybody. I'm hoping someone on here can identify these. Last Saturday I was digging in the yard here in Alva to plant some citrus trees. At about two feet down in this area it's all coral and i found this conglomeration wedged under a cypress root. the tree is over 4 ft in diameter. i thought these were lizard eggs but after gently brushing the shells out with a soft toothbrush and dawn soap, i think these might be pearls. two of them actually did separate as you can see they're on the desk. we're seventeen miles from the ocean and this property was a cypress swamp prior to our house being built in 1974. Any thoughts on these ? My wife wants me to encase them in resin because they're unusual looking . Thanks.

Hi, I found this giant oyster in the Mexican Golf. It weights around 13kgs. I found this article about something similar, where they did a MRI on the oyster. - https://www.dailymail.co.uk/sciencetech/article-2154813/amp/The-100-million-year-old-oyster-times-normal-size-undergo-MRI-scan-contains-worlds-biggest-pearl.html and here the same story with more details, but in spanish - https://insolitonoticias.com/ostra-fosil-de-145-millones-de-anos-podria-contener-una-perla-gigante/ Cheers.

Hello all Here is a companion query for help. This item is flat, tapered to the top and slightly concave from the underside. The two pictures are a top view and a bottom view. It is about 2” thick. The scaliness, if there is such a word, looks like Exogyra, but does not have the curved narrow end described for Exogyra. I assumed this was a flat mollusk shell when I picked it up (E of Capital Reef, south of Rt 24, about 4 miles outside the park) but can’t find a match with the limited references I have. Help appreciated. Thanks. Tom

Hi, a friend of mine told me he found some Placentyceras in a place where the geologic ages go from the Albian to the Turonian-Santonian, but most of the stratas of that place are Cenomanian. I believe this fossil is not an ammonite, but rather an Oyster or a rudist. I mostly think about Requienia or Toucasia. The geologic file mention the name of Toncasia bayleia. Do you know if Toncasia is a synonym of Toucasia and do you think i'm right thinking this is a rudist ? Lenght : 7 centimeters.

I should have posted this long ago, but am going to do it now, in the hope that then it is behind me and then I can look forward to future adventures. Due to ill health from 2012, finances and responsibilities, I have been unable to do any personal collecting except for this one wonderful trip which reminded me that I've still got it in me. In October 2016 wifey and I were relaxing in a bar on Tarifa beach, the southernmost point in mainland Europe, located at the south-western corner of Spain, opposite Tangier, the two Pillars of Hercules that are the entrance to the Mediterranean from the Atlantic. I noticed an island connected to the mainland by a man made causeway. it had a lighthouse on and some ruins, so I thought that being only a little distance, I'd go and explore. Here is the location, to the left of the picture is the Mediterranean, to the right, the Atlantic. There are no more location pics, I'm afraid, as wifey can't be prised away from bars very easily and she has the camera phone, but the island was closed to visitors without a guide or permit as it's a place for protected birds, the lighthouse and Napoleonic fortress ruins. But to the left of the causeway was a small beach with exposed rocks and even a little notice board explaining that the rocks were a Miocene oyster bed 5 to 10 million years old. My interest was aroused so I clambered about the beach and found the fossils in the next post. Very pleased with myself, I was, especially as I had no tools and the rock was really seriously hard. Had to use other bits of rock as hammer and chisels. And my breathing held out pretty well. I can still do this! Life's Good.

I'll post a full story in trips when I get time, but I was searching around a new spot, being unsure of the formation (Austin I assume now) I was picking up everything I found including oysters which I would normally leave, I assume they're exogyra or ilymatogyra but the Mark on the back is strange to me, 2 of the three I picked up had them and I haven't seen anything like it in pictures. Species and out formation ID would be nice

I found several of these on Myrtle Beach. I think they’re my favorite oyster fossil. But I’ve checked a bunch of online databases and can’t figure out the name of it. It’s gold in color. I should’ve put a measuring tape next to it. They range from 4 to 5 inches long . Thanks! paula

A Taste of Georgia's Eocene: Sandersville Limestone (9/22/18)
MeargleSchmeargl posted a topic in Fossil Hunting Trips
Well, it's been a while since I've been out and about growing my collection of long-since-perished critters, so needless to say, I've been restless. I've been somewhat late in putting up my trip report, as this was doubling as a school project (writing a news feature on PAG (Paleontology Association of GA) for the school news site, 3ten) and everything at the place was taken on an NVidia whereas usually my smartphone does the trick. Anyway, enough BORING excuse backstories! Let's get to the meat of it! This past week was rather hectic for me. A trip to Pensacola where I swam in September ocean thinking it was July, a wisdom tooth surgery happened and the Braves got that sweet, succulent NL East crown, punching their ticket into October ball. Adding this trip on top of that made my fall break jam packed. I'd been waiting for an eternity to go to Sandersville with PAG ever since I heard of the announcement on their page way back in August. As soon as I was greenlit by my the editors of the school news to cover the event for school news, I was going, half dead from wisdom teeth or not. It turns out I wasn't as energy-sapped as I thought I'd be, as my wisdom tooth recovery had been pretty speedy (thank the Lord). Everyone going met in a Walmart parking lot more minutes away. We got told of the treasures we'd find (though I already knew): Periarchus sand dollars (heck yeah!) Crassostrea Gigantissima oysters (yes pls!) And shark teeth/Ray plates (good for me!) After that and a brief discussion on directions and my covering the trip for the school news, we headed off about a minute or so down the road to the landowner's property. We pulled in on a dirt road, and parked in an area of tall grass. The actual site itself was a short trek through the woods to get to the small creek where the Sandersville Limestone was actually exposed. It was somewhat difficult to get the camera equipment down to the creek along with the gear which I was actually using to get stuff out of the matrix, but it wasn't unmanageable and was definitely worth it. Here's what the much of the creek looked like: After getting together all of my pictures for the news, I went ahead and got to the fun part: finding stuff! My first and primary objective was the Periarchus quinquefarius kewi sand dollars, as with my trip to Montgomery in July, I have officially caught the echie bug. It didn't take very long to start finding them protruding from the limestone: After taking four with me, I moved to my next target: the Crassostrea Gigantissima oysters. These hold a special place in my heart, as my uncle Frank and I went driving near Griffins Landing trying to find an access point to get some of these huge oysters to no avail. Also, I heard that these oysters can only be found in Georgia (though i'm not sure about how true that statement is. Any answers regarding this?). To find them, I went a way downstream to where this Oyster exposure is: I was already getting packed with inverts, and I had a lot of stuff to carry back to the car, so I only took the most complete one I saw. Last but not least, I made a pitstop at where most of the group was sifting at a particularly deep and clay-ey part of the creek for shark's teeth and decided to indulge myself in a handful. Here are some of the other guys getting sift-fulls: Next post: My finds of the trip

Need help identifying clam shell maybe? SOLVED: LIKELY EXOGYRA OYSTER
PSchleis posted a topic in Fossil ID
Ok, another new one for me today. I picked up one at Myrtle Beach, SC because it looked interesting, then found a second almost identical one. Now I'm thinking it's something worth knowing! It's dense and heavy. The top has a gray metallic sheen to it. Both of them have a middle circular area that looks rusty, and as if something had been attached there and pulled off. The back looks completely different. Where the front is smooth and shiny, the backside is rather dull. It is comprised of layers, and they layers come together in a knobby area at one end (again, as if perhaps it had been connected to something.) Overall, it really looks like a kind of clam shell to me, but the metallic sheen, rusty circle and layered interior don't look like any clam I've ever seen. Thank you again! - Paula
