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!

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

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.

Yesterday: fossil hunting with my girlfriend in Limburg. Many Cretaceous limestones and good fossil specimens! Including a really big and complete Pycnodonte vesicularis (Lamarck, 1806). My second biggest Pycnodonte. Many belemnites (including a real cool black one!), two pieces (including a big one) from the same genus (Pycnodonte) and one sea urchin Echinocorys sp. or Echinocorys scutata (Leske, 1778). Also one recent cow/bovid tooth and a piece of vase. The two photo's on the right are from another (earlier) trip (fossils are on the ground in a field. Finds: one sea urchin Cardiaster granuloses (Goldfuss, 1829) and one belemnite (many more belemnites were found). Genus Belemnitella or Belemnella (Pachybelemnella) sp.)

Only one I've ever found like this. What it is exactly, I don't know. Found in a load of limestone road base, likely from a local mine.

From what I've learned crinoids aren't from around here, prob from way upstream fill rock. Here being Dallas creekbed in Eagle Ford shale. Its so unique with the patterns, almost looks carved, just guessing part of a crinoid because of the cylinder shape. What the heck is it?

Thanks beforehand. My young granddaughters (8 and 5 yo) have went fossil hunting in their backyard around Lake Cumberland in Kentucky and as I am not experienced in identification and cleaning techniques I appreciate all help given to identify several examples of what we collected.

Found this on gravel bank in creek close to DFW, in a narrow band of Alluvium smack dab in middle of Fluviatile terrace deposits. I'm not sure what to make of it, appreciate input!

This little thingy was in Mississippian Redwall limestone in central Arizona. It was in a section of the Redwall with very few other fossils. It's about 10mm long and 7mm wide. What do you think?

I'm looking for assistance identifying a large fossil that was in with skids of limestone rockery from the Niagara Escarpment. I have uploaded a series of pictures to Flickr https://flic.kr/s/aHsmTVvrFN and attached one image. It looks like a type of coral. There is lots of texture on the surface. When opened up, it is full of long columns. Thanks.

Hi, I hope this is ok to post! Whilst out on a walk we came across the attached fossil. Whilst I appreciate it doesn't seem much, its quite distinct and any help to identify it - and help educate the small hands which has been carefully cleaning it - would be very much appreciated. I might have some explaining to do that it isn't a t-rex We are located in Derbyshire, United Kingdom. If anybody has good references for teaching kids (6 year old and 3 year old) about fossils it would be great to have them.

Hi. Found among the huge limestone layer at the Caney River in central Washington County, northeastern Oklahoma. Pennsylvanian. It's a little closer to Kansas than to Tulsa. A few miles east of the Osage Hills (or Rolling Hills of the Osage, depending on the which map).

So, in trying to identify my local limestone for sure, I've gotten the need to try to extract conodonts, and I'd for sure like to see other microfossils. I know this has been discussed here before, but I was wondering what might be the correct or tried and tested method for home, using obtainable chemicals. The last thread I found was talking about lab processes and clouds of white smoke. I've heard different things from using acids (Vinegar), Hydrogen Peroxide (3% limit at Walmart), to Kerosene. Also a need for sieves, filters, etc. Curious for a guide or advice for effective home methods. - Clint

San Antonio, Tx I pulled up a piece of sediment from my yard and this came loose also. I have no idea what it is. I have another rock very similar but much larger.

Hello all, Im very new to this. Currently I'm in Czech Republic and some time ago i found my first interesting fossil in this area: https://www.google.com/maps/place/Český+kras+Protected+Landscape/@49.9290996,14.178056,13.17z/data=!4m5!3m4!1s0x470ba30d37e892c5:0xd582af42389f3a3b!8m2!3d49.9355334!4d14.1819469 I don't have any background in palaeontology and decided to get some help from enthusiasts with experience. It's one rock. The main Fossil on "top" is that Trilobites tail? What are those yellowish formations visible on the side of the rock? They stand out and have organic shapes. Are they bones?

Hi all! Perhaps this is a dumb question, but I' still new to the forum as well as the hobby itself, so I offer a teaching moment - In round rock, (just north of austin in central texas), I have a location at the base of a limestone cliff where after some gritty mining efforts I've come across an extremely dense pocket of what I've been informed are internal casts of rudists. That ID was great!, but I'm having trouble learning about what the actual organisms were like. I've tried researching quite a bit with no clear picture of what these are that I'm discovering. Also geologic maps of the area have some disagreement, so the exact spot could be Edwards limestone, eagle ford, or buda limestone. I understand (I think) that these were some variation of a mollusk but the story ends there. Discovering these would be even more magical if I had a proper understanding of what these organisms were like, looked like, and what role they played in their environment while they were living. I know these are a common fossil so many of you will have a wealth of knowledge about these. Please enlighten me, I'd love to learn! Below are some examples for reference:

Time Period: Pennsylvanian Location: Missouri Formation: Most likely Winterset limestone Hello! I am currently puzzled on weather or not this is a Conodont or some fragments from Brachiopod. I am thinking it could be broken parts of a shell or broken pieces of a Brachiopods fossilized lophophore supports from a very small specimen! I have not found any conodont specimens from this location yet as I usually do not hunt for them Images in natural file size: https://imgur.com/a/KNeqtZn

I found this in an area of North East China. The area has some volcanic history, and a lot of granite mines. I thought that I had it figured out, but am torn on what type of limestone it is, thus what era it could have formed during, thereby leaving me clueless about the small, potential fossil! Any help would be appreciated! Also, any clues on how the granite became fused to the limestone?

When cleaning up rocks I brought home today, I found this little piece that I didn't originally target. It's pentagon shape makes me believe it's for sure a fossil. I've never found anything like it, so I feel like I'm about to get an education here. Perhaps part of a crinoid? Whatever it is, I don't have the experience, yet. Also noticed the indented hole on the top. Maybe part of it, maybe not. It's way too centered I think to not be part of it. Underside. It is convex with a small raised ridge along the edge. Sideways view of the underside with scale: Front view with scale (non focus stacked) There is a porous layer on top, which is very similar to crinoids I've seen in the past. I've only ever found stems.
