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.

I have found a few of these oyster shells near the top of the upper Glen Rose. This is about the only real fossil I find in the area I can look. Hope that it's identifiable. There is an Edwards (Fort Terrett) cap on the hill I find these on. I don't believe they are washing down from there but it is possible. All I have found have very flat bases with an obvious wedge shape to them. Only found what I assume are the bases, never a top. First post on here so don't be too brutal.

So I’ve been out of commission for some time due to back surgery. Just starting to work my way back into my favorite hobby. While cutting the grass on my property I found a recently exposed chert outcropping. After doing a little digging I found these two shells that were in a small area along with some chert, chert with agatized coral, and some beautiful colored chert. I have a small freshwater creek that runs through my property and this was within maybe 20 feet of it. They look like fossils, but I’ve been wrong before. Thanks in advance and I look forward to starting to plan my next expedition!

So, I found a large complete Oyster at Poricy Park, NJ and was cleaning it as gentle as I could as it is very fragile but after a while of running warm water over it the two halves separated in it was nothing but hardened mud, silt or clay of some sort. But inside to one edge of the shell against the bottom half was something hard, not round but triangular in shape with about 1/2” sides. This was the only thing found within the two halves except for the very fine sediment. Opinions?? Thank you.

Hi everyone, Collected this fossil a while ago in or around Cap Gris-Nez, France, and was curious about what it exactly it is. it's about 8.5 cm. Thanks in advance.

Thanks for any help putting species IDs on these marine fossils from Magoito Beach, Portugal. My best guesses are as follows: 1-12) Oysters, unsure of species 13-20) Clams, original material and steinkerns. 13, 16 and 19 are quite "tall", others rather flat. 21, 22) ?? Possibly a coral? Or crinoid fragments or a trace fossil? 23, 24) smaller oyster pieces 25) a mussel? 26-29) gastropods 30) shark tooth - possibly goblin shark? Sadly fragmented, but has distinctive pair of lobes at the root midline 31) ?? intriguing paddle-shaped structure with a distinctive mid-line 32-38) bonus calcite and gypsum crystals

Hi all, not sure if anyone can help with this. A long time ago (like 35 plus years) I went on a fossil hunt. I was little but believe it was somewhere in New York. We went for a hike in palisades on the same day. We picked these oyster shells and were under the impression ever since that they’re fossilized. They are hard and heavy. I would value any input anyone may have about them. Thanks in advance.

Anyone know the species or genus of these?

Found in Grayson formation Tarrant co, have searched and searched and finally came across Pseudoperna congesta, if that's not what it is I give up . Can't tell what they were attached to, assuming it's a mineral encrusting them? Or are they encrusting the mineral? My guess is it's some form of iron oxide, perhaps magnetite? Scale is cm.

Looking for some help on this shell specimen. It was part of a large rock and mineral collection I acquired not long ago but unlike the rocks and minerals this was not labeled, so I have no location info to offer. Thx in advance.

Went hunting with a friend yesterday on the Peace River. Saturday is unusual for me because of increased river traffic on the weekends. Since I can hunt any weekday, I tend to avoid weekends. We were prospecting, looking for gravel. As always interesting finds: Not too many , but interesting .. One location had agatized shell: I guess this might be the equivalent of a RucksPit Calcite Clam, but this half bivalve is pretty complete and clearly an oyster. I am not positive on the creation process but think I ought to name it a silicafied Oyster. I would like to find more of this.... @Sacha @MikeR Then I picked up this interesting shark tooth. Any time , I have to roll a small shark tooth in my fingers a couple of times wondering what it is, that's the time I need to reach out for help . @Al Dente Moving locations , I came across an oddity... White shark roots coming out of white rock, under the sand and gravel of the Peace River... This will get multiple visits if it keeps producing teeth like these. A couple of deer tines, a broken Equus magnum, gator tooth, a dolphin jaw fragment, and a numbers of broken teeth, horse, bison, camel, and then this oddity. I am really not sure what it is besides a really beat up tooth.... At first, I thought Equus long upper tooth, but Equus would have the thin white lines , not the wide upper bands. then I bounced between Mastodon and Mammoth. The 3rd photo seems to show more agatized material, just slate instead of golden color. Size 40 mm long 15x20 mm. I finally settled on Mammoth fragment with the enamel crumbling and the cementum agatized. I am pleased by the interesting and unusual finds, a long day exercising in the sunshine with friends. and finding a couple of locations that I will return ...
