Hi ! My girlfriend noticed some fossils from a cimetery wall just next to my appartment (which is located in a suburb really near Paris). Thanks to some geology museum in Paris, we identified this limestone to be from Lutetian. It also happens that the fossils can be directly picked off the rock by hand without damaging the wall. So we got a few of them. Here is what we found : I believe most of them are Sigmesalia, except for the bivalves which I suspect Crassatella. There are two specimen though that draw my attention : I don't think they are from the same species from the others. Maybe some Cryptochorda stromboides I mainly used the forum to find matching species with those, I'm not quite sure whether my identification (nor the method I used) is correct or not. I hope you find this interesting (and beautiful ofc) !

New Eocene Castle Hayne Exposure; Vertebrates Galore
sixgill pete posted a topic in Fossil Hunting Trips
Hi everyone. It has been a while since I have made a post. Between some health issues and all the RAIN we have had here in NC this summer, the trips have been few. Not to mention all of the quarries still being closed due to covid. Recently I was granted permission to search a small, private agricultural limestone marl quarry. It is Eocene Castle Hayne Formation, Comfort Member. Now before anyone asks, no I will not say where or nor will I be bringing anyone to it. It is very small and my permission is very tentative. I have to get permission each time I go. It is a smorgasbord of Shark teeth and verts, sawfish rostral teeth and verts, fish parts. Other than broken pieces of Periarchus sp., a few crab claws and a few startfish ossicles it is rather void of invertebrate fossils. The marl is friable limestone. Here are a few of the teeth found so far, some of the rare Castle Hayne teeth. I will add more pics as we go along of other items found, including some nice C. auriculatusand some huge sawfish rostral teeth and verts. Heterodontus cf elongatus Hexanchus agassizi Heterodontus cf elongatus Nebrius obliquues

Here is a weird fossil that was found amongst corals from late jurassic 150Ma. Is it a mollusc shell, a tooth, a bone? Its my first potentially kool fossil ever!!! I am hoping its a fierce sea creature!
-
Found this amongst other critters in the Upper Glen Rose near Spring Branch, TX. I'm at a loss, but I'm thinking it's a worm. Also, I'm not a worm guy. Clues, hints, full-blown answers, and red herrings appreciated. :-)

This rock was part of erosion control on banks of creek in Cretaceous Eagle Ford so it is not from here and that's all I know. It's a mass of crinoid stems with a couple things I can't identify, first object is similar to the stems but it's translucent and doesn't appear segmented, next object is also translucent with stripes. Last pic maybe bryzoan?

Hi, my son was desperate to find a fossil.while on holiday. Can you help identify the 2 things we found? A geologist friend suggested one is coral. The pitted texture seems to go right through to the other side. Thanks for any help. Aileen

I've been finding fossils in limestone, sometimes I find fossils in rock that also appears to have these irregular lines interspersed. They are all shapes and sizes, I’ve attached some pictures. I am just curious as to what these are. Carbonized plant material? Or just inclusions in the rock?
-
We found this in a tributary of a creek that runs through my sister's backyard in St. Louis, Missouri. Also found druzy quartz, brachiopods, bryozoans, and other molluscs and a few geodes. It looks like burrows in rock (flint?) Top photo shows cluster of shells found at the bottom of the tube. The rock is about 1 square foot in size. Is it a trace fossil of a burrowing mollusc? Any information will be greatly appreciated.

Hi guys, I recently started learning to fossil hunt for my son as he loves dinosaurs and on our first trip we found this in a limestone. I am completely new and really sorry if this borders on an insult to some of your experience but I have no idea whether to crack the rock open and have a look or whether I’d end up breaking a fossil of some kind if I did or whether it is just a mineral running through of some sort! There was a much larger rock with the same streaks but in a diamond shape on the beach so if it is a fossil I’ll be running back there ASAP Thank you in advance (I’ll thank again afterwards too!) and I’m glad to have found a community on here to help further my knowledge!

As the hammer in the picture shows, it is about 10 inches long. Thanks for any help. So regular no sure if it was organic matter, but is now limestone.

After finding a few larger trilobites last year, I found my first trilobite of this season today. It is the smallest trilobite I have found yet, at 'only' about 3 inches in length, but it looks to be inflated and fairly complete. I am trying to determine if I should have this prepped, like my other ones. Thoughts? Also, am I correct in assuming this is an Isotelus, as with the other trilobites I found last year? Thanks,

Found this fossil loose on a limestone shoreline on St. Joseph Island located at the north end of Lake Huron in Ontario, Canada. I am a civil engineer and have some experience with rocks but I’m fairly new to fossils. Any help identifying would be great!

I am wondering what fossils you can see in these rocks. they are all carboniferous limestone (prehaps not the red/brown one). I can see Bivalves, coral, crinoids, brachiopods (I think), And nothing else. Why aren't there other carboniferous life. (I understand soft parts go) These rocks are packed with fossils, what can a real paleotologist see?

Hi I have syringopora coral that I want to make more visible. Right now most of it is buried in limestone. I don't want to remove all matrix, just make "tubes" more visible and appealing. Will soaking it in white vinegar do the job?
-
Hi I found this fossil in gravel pit near Zgierz, Łódzkie, Poland. I think it's syringopora coral, but I'm not sure. I think it's worth noting that fossils from this area are glacial erratics.

I've had these for close to 20 years now and have shown some of them before but figured it was time to do a proper job of looking for info. (If I did before, I can't find the topic) I know nothing about these, either ID or location. They were part of a batch of fossils I received from an old rockhound couple in Nanaimo, which wasn't too carefully curated (a common problem with rockhounds/casual fossil collectors). Looking for info on the mystery items from that lot is what brought me to the Forum in the first place more than 10 years ago. I know Riley's Canyon, Utah has red corals, but lately I'm seeing them from other places like Arizona also, so I'm not at all confident. It's a reasonable assumption that they're from somewhere in the US Southwest as it was (and is) common for rockhounds in our area to travel down there in the Winter for better weather and abundant rockhounding options, but that doesn't narrow it down much. Any ideas? Not all of them are preserved in red color, as you'll see below, so I'm not sure they're from the same place, but they were kind of bundled together when I received them. For reference, I'll number each pic. 1: The lot 2: 3: 4. Sliced end: 5. Sliced pair: 6. Some seem to be water-worn to some degree - these ones more so: 7. Is this a sponge? 8. Chaetetid? 9a/b. These are the ones that have little/no red, so I'm not sure if they're from a different location or just a different preservation from the same site: The larger piece is sliced. 10. This one looks different again, so it could be from a third site....

Here is a fossil I found in some carboniferous limestone. Does anyone know what it is. It was found in the limestone of the berwick upon tweed area N england.

This triangular prism is covered in small fossils of coral, bivalves, and trace fossils. The main question I have is about these 6 curvy lines going through the entire rock. Bioturbation? Stromatolite? Erosion? It was found just outside of Las Vegas.

I found this oddity today while examining some fine grained finds. This is basically soft limestone, where the rock is pretty soft and most of the calcite has been dissolved. I forgot to include a scale, but if I were to guess, it's about 1/2" across the structure (12.7mm). I plan on measuring again. There were several of these throughout the piece, but this was the most prominent. My guess is some sort of Bryozoan.

Hello again, I was doing some surface collecting in Oakland County michigan-- typically the fossils around here are preserved inside of pieces of limestone... I'm no expert on fish or sharks so I'm not sure what exactly this imprint is, but it reminds me of a tooth. Would anybody be able to confirm/deny this? The rock in question is about the size of a dime. Thank you!

Help identifying Devonian fossils in limestone from Western NY
Rock-Guy-17 posted a topic in Fossil ID
I grabbed all these samples over the years from the same rock quarry in western New York, which excavates the Middle Devonian Onondaga Formation. I believe most of these are corals, but I was hoping someone could help specify what type of coral so I can organize them a bit better. I resized the pictures with the provided links to lower the quality, hopefully they are not too big still. Appreciate the help. 1. Two different fossils in this cherty material, on left I believe this is Rugose Coral because visible septa, but on the right above the letter "L" in the coin I am not sure if it is even a coral 2&3. A tabulate corals, I always believed this to be Favosites, but also some images of coral Emmonsia that I had not heard of that look similar, but I can't find many other sources on it. Is there a way to tell based on the pattern what type of tabulate coral it is? 4. Brachiopod? Bivalve? Not sure what more I can figure beyond that. The matrix for this one is very chalky

Small Fossil Collection - Batesford Quarry, Geelong, VIC, Australia
PaleonLachie posted a topic in Fossil ID
Hello fellow fossil hunters. Below is a photo of the array of fossils I found. Each fossil is labelled with a number and it would be awesome if I could get each one identified. I thought ahead and took the photo on grid paper with each square being 5mm. Item 1 is just some quartz crystal I picked up, item 4 is a piece of some unidentifiable shell and the rest are legit fossils. I am a rooky and an amateur so please let me know if I get anything wrong or if I need to add any more detail. Location: Batesford Limestone quarry, Geelong, Victoria, Australia. Geology: Sometime between the Miocene to Oligocene Epoch. Formation: All specimens were found in loose waste heaps inside the quarry at the deepest part. Assembly: The Geelong area was once part of an ancient inland sea hence the limestone deposits. The fossils consist of a lot of marine life, crustacean shells, ancient Mako shark teeth, some sort of cone shell worm. Some Megalodon C. teeth have been found in the quarry too (dont know if that helps out) Discovery: All items were found in a loose pile of ground limestone at the deepest part of the limestone quarry. Characteristics: Item 1 is just some quarts. Item 2 looks like the shell of some crustacean, reminds me a lot of the ribbed shell of a lobster (same as item 9) with the small and circular cones protruding up and away from the shell. Item 3 is a very small snail shell, very similar to the small ones you can find on any Australian beach. Item 4 is a rough cut out of some shell of some sort, no major identifiable features besides being smooth. Item 5 looks to be some sort of forking coral with branches that have been visibly broken off at some point. Item 6 appears to be a part of a mollusk shell, the edge is circular with different patterns further up the shell following in the same direction. Item 7 looks to be part of a large snail shell, larger than item 3, with brown streaking marks following the grain of the shell. Item 8 is another part of forking coral, I believe its a different species than item 5 due to its smoothness and lack of branches as compared to item 5. Item 9 is identical to item 2 only being a little smaller. Item 10 appears to belong to a create similar to item 2 and 9, however, the piece looks to be whole (as in not broken off), a standalone, small plate of armour, almost like a 1 x 3 flat Lego brick with the same type of protruding cones as the previously mentioned items. Item 11 is what I believe to be the tooth of a Isurus Desori (Mako Shark) after doing some research of other finds at the quarry. The tooth is almost banana like in shape being extremely narrow and sharply pointed, made for penetrating prey's skin. Item 12 is very similar to item 15, being a long cylindrical shell, almost like a fossilised worm hole with the exception of a small bulb on the tip which is more profound in item 15 and item 13. Item 13 has more details in the form of tiny dots drawing vertical lines down the cylinder of the piece with a similar bulb to that of item 12 and item 13. Item 14 appears to be part of the shell of a what Australians call a "Pippy", its scientific name being Plebidonax Deltoides. Item 15 is identical to the smooth item 12, just a bit longer, however different to item 13 which looks to be the same species given the same shape and bulb at the tip with the exception of the detailed bumps running down the side of the cylinder.

We are on the edge of the Vale of Clwyd in North Wales surrounded by limestone. Much of this limestone is full of fat, coiled fossils which I initially thought were ammonites (on the basis that in my ignorance coiled fossil = ammonite!). I have since learned that there are no ammonites in these rocks - correct?. Today though, my wife was doing some garden digging and found the specimen shown in the photos attached, loose in the soil/rock debris. This looks like an ammonite to me! Can anyone tell me what it is and whether this is its 'birthplace' so to speak. The scale in the pictures is MM.
