Found these in a limestone formation near Bocairent, Spain. From some quick research it seems to me like these might be from the upper devonian, and some look like nautiloids? One of them looks like a coral. Perhaps crinoid also? Would love some help on IDing these if anyone has any ideas!

Hi! This was found near Meridian, Texas, US. The geographical area has a large quantity of limestone rocks and boulders filled with shell fossils. We were exploring a boulder and realized an area was slightly loose, and we pulled out this item that was wedged within the boulder. There is a smallish lake nearby. The boulders were manually placed to block cars from parking on the campsite, though they were likely sourced from the area as there are naturally occurring ones all throughout the park hiking trails. Appreciate any info on what this might or might not be!

Hello everyone ! I received this fossil as a gift from my grandfather, a retired geologist. I've always wondered if it was possible to trace the species of the two fish. The fossil was presumably taken in an area of central Italy, probably in the Apennine area of Lazio or Abruzzo. the two fish measure just under 3 cm. Moreover, do you think it would make sense to continue cleaning the surface completely to perhaps discover new ones? Thanks so much !

I just went to a local rock and fossil shop in Montana and they had an amazing selection of fossils for really reasonable prices, so I ended up getting quite a few. They had a lovely Solnhofen rack, mostly filled with fish, insects, and coprolites and some beautiful squid but I saw this questionable creature in the corner for very cheap so I decided it was worth it to purchase. I am guessing it is a jellyfish due to the shape, and I hope it is, but if it is something else, I really did not waste my money. It's around an inch and a half in diameter (4cm.) Just hoping it's not a coprolite lol. Anyone know a thing or two about Jurassic Jellies? Pic below, I can take a better quality photo in the daytime if that helps.

Hi! Thought I'd give this a shot: I found this piece as a kid, and have held on tight to it because it's always been my "cool rock I found all by myself". Decades later, my opinion hasn't changed. Found in a rural part southern-central Ohio. Decent weight for its size, would definitely hurt if someone threw it at ya. My only query is that I have no idea what it is, as a super amateur mineral collector/enthusiast. Some strangers on the internet have pointed to it being limestone, but no guesses on what's imprinted on it (if anything). Would love to hear some opinions, or just for someone to flat out tell me it's been nothing special this whole time. Happy almost New Years!

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.

Fossils from Magoito, Portugal (Cretaceous limestone cliffs)
tobie-lisbon93 posted a topic in Fossil ID
First trip fossil hunting. Mix of vertibrate fossil, unidentified trace fossils, and pretty rocks (hard to tell from from the photo). Second batch is from Caparica, Miocene, including shark teeth (probably maku). Anyone want to help ID some?

I found these 2 fossil fish in a flea market, and as often in these conditions there was no indication of provenance and identification. please help me if you recognize these specimens. thanks

Hi - I am not sure what I am looking at or if I should bother with these types of finds. Could anyone shed some light and provide direction? I am finding a lot of "large rocks" like this in small dried-up basins between hills. The area is close to the Harpeth River in Nashville, TN. Thanks for any advice in advance. My daughter and I like to go exploring and want to guide her in what we are finding.

Hi everyone, found this fossil in limestone area in United Arab Emirates which was formed 66-74 mya, according to local geology museum. Not sure what it could be but looks very pretty for sure This fossil was found on the ground in sandy areas where bivalves and small shells are found quite abundantly.

I’ve had this forever, I think I found it in Middle TN. I initially thought it was a cephalopod, but I know more now, and I don’t see any septum(s). What say ye? Thanks!

Hi, I don't have any information on this specimen since I believe the rock that I found it in is foreign to the area I discovered it. Although I think the rock is from somewhere around the Western Pennsylvania/Eastern Ohio area. It is approximately 2.6 cm by 2 cm. Just hoping someone has some idea what it is. Thanks again.

Hey there Fossil Forum. One of my friends found an interesting specimen showing a well preserved (lamellar?) microstructure inside the Beauharnois Fmt limestone (Joliette area, Québec). Beauharnois Fmt is Ordovician. To me, this could very well be some kind of colonial animal (like a bryozoan or graptolith), but I have never seen a similar one where I live so far. The dual branch architecture makes me think of a graptolith, while the somewhat "lamellar" microstructure reminds me of a bryozoan. However, I would not be surprised if it was something entirely different. Any guess? Please see pictures below. Specimen is 5 centimeters long.

Hello! I am very curious about this find. Like the title says, this was found in mid-Missouri in a creek bed. There are a few hexagon patterns I can see that are connected but I truly have no idea what I'm looking at. Any ideas?

Does anyone know what this might be inside of this limestone? Found at Maskuta Creek, Alberta, a stream connected to the MacLeod River 4 km from Drinnan in the Hinton Valley

I apologize in advance for the photo quality, and the fact that I did not have a ruler with me when I took the pics. I see these things EVERYWHERE. The ones pictured here are large (6-8”, 15-20cm), in limestone slabs. But I see them in smaller sizes, in rocks that I pick up. The rocks often have recognizable fossils in them, too: cephalopods, brachiopods, crinoids, bryozoans. I am thinking maybe these are internal structures, perhaps of brachiopods? I’m starting to think I am crazy…

Howdy! I found dozens of crinoid stems recently and most of them seem to have a thin layer of matrix attached. They were found in limestone, but I don't even know what mineral they've been fossilized in...calcite? Would I be able to remove the matrix with sandpaper and perhaps even polish them? Would sanding them remove visible segmentations? All help is appreciated, thank you.

I was searching around a local stream when I found some limestone with dozens of crinoid stems. I can't say what the formation is as I think they rolled down a hillside which had foreign limestone blocks to prevent erosion. If they are native, they would be Pennsylvanian Glenshaw Formation. Each of them has stellate lumens and many have a pinkish hue. Can anyone tell me what variety of crinoid and is it possible to discern the period? Thanks.
-
Hello! Is this a crinoidal limestone rock? Dimensions are 7 x 5 x 1 cm. Wet: I picked it up in Braila county, Romania. A few hours ago. Thanks!

Pitstop on the Road to San Antonio. The Salenia Texana zone.
Mikrogeophagus posted a topic in Fossil Hunting Trips
Last weekend, I made the trip down to San Antonio to tour and interview at a school. Though the drive wasn't all that long, it was enough for me to decide to take advantage of the opportunity and make a visit to one of the most famous Lower Glen Rose roadcuts in the Northern San Antonio area. In recent weeks, I have finally hopped onto the echinoid train and begun rapidly expanding my urchin collection. To keep the ball rolling, my goal was to find at least one decent specimen of Leptosalenia texana. Luckily for me, the layer I was heading to has been dubbed the "Salenia texana zone" for a reason. Local echi hunters will probably recognize this spot pretty quickly. The day was hot, but I'd grown used to the heat after the Texas summer we've had (or are still having?) since May. I first poked around the more accessible parts of the exposure. I wasn't surprised to see dozens of urchin shaped holes dug into the wall; it is a popular spot after all. I steadily made my way across the exposure, prying out the stray irregular echies as I could find them. Half an hour passed and I was still at a loss for completing my initial goal. I decided switch things up and worked my way through some bushes to less friendly spots that others may have not wanted to bother with. As soon as I set my water bottle down, I spotted my first piece of salenia sitting right there next to it. The ornamentation on these things are so alien, they really jump out of the background unlike anything else. Pretty quickly I spotted a whole mess of leptosalenia just erupting from the hardened clay. Thankfully, I brought some tools and got straight to work popping each of them out one at a time. Most of them weren't all that pretty, but the thicker shells on Leptosalenia texana help with keeping them better preserved in a higher ratio than most other urchins (none of my irregular echinoids looked all that great at least). The day continued more of the same and before I knew it, it was time to continue my way down the road with a baggie full of goodies. It's not every day you get to add a genus and three new species to your collection! Pics: Better specimens of Leptosalenia texana Irregular echinoids. Top is Heteraster obliquatus and bottom two are Pliotoxaster comanchei Misc. Fossils. Left to right: Bivalve, Porocystis globularis, and echinoid spine. If anyone knows which urchin that spine goes to, let me know! For those who are wondering, the interview went great! I'm gonna be on the road again to another big city in Texas where I will get to check out a familiar spot (assuming the water level stays low) so look forward to a future report! Thanks for reading

Hi all, first time on here and I have a fossil that was found in South St. Louis County that I would love to get a potential ID on so I can learn more about it. Thanks for any help you can give me.

A week ago I made the trip out to one of the roadcuts on loop 360. I realized that I had been neglecting visiting the west side of town which, although very different, is just as rich in fossil history as the younger east. I want to also thank @erose as he has posted lots of useful information on the cuts and what sorts of things can be found. I arrived in the afternoon and slowly climbed up the gravel to get to the first bench. I made the rare good decision to hunt on the side of the road that would shield me from the sun, making the temperature nice and cool, perfect for fossiling. Despite the proximity of the road, the area felt surprisingly secluded. All atop the bench were a variety of giant boulders that had fallen from the many formations overhead. I wasn't sure which ones were best to look through, so I ended up going mostly for the softest ones. They were absolutely packed with everything from gastropods and bivalves to the occasional tiny regular echinoid or algal fruiting body. I took occasional trips up the gravelly incline to the top of the cut, but really it was just more of the same stuff so I decided to focus on the easier-to-traverse ground below. It really didn't take long before my pockets were heavy. The day was periodically graced with more unusual finds like irregular echies and a large fragment of an ammonite (whole ones are very rare here). Before I knew it, the sun was beginning to set and it was time to head back to the car. Most of the stuff was pretty easy to clean at home. A lot of the limestone popped right off, though some was a bit harder to get. An interesting thing I noticed was that some of the fossils had distinct parallel engravings on them. It looked a bit similar to the damage I have caused using vinegar on limestone fossils in the past. I wonder if acid rain was the cause for these markings. Anyways, here are some pictures. Overview of the better finds: A). Irregular Echinoids Heteraster texanus B). Regular Echinoids. All Loriolia? C). Misc: Metengonoceras? ammonite on top. Below from left to right is a Porocystis globularis algal fruiting body, Neithea texana scallop, and Ceratostreon texanum oyster D). Gastropods. Back row: Anchura. Front row (L to R): Nerinea? (From Bull Creek Fm), Unknown, and Natica I will definitely be back in the future and might check out some of the other cuts nearby. Thanks for reading!
