Mellita caroliniana inside a Dinocardium robustum
Echinoid Express posted a gallery image in Echinoids
From the album: My Echinoid Collection
Mellita caroliniana inside of a Dinocardium robustum Waccamaw Formation Early Pleistocene (~2.5 Ma) Columbus County, North Carolina, USA Self collected in November, 2023 This is my first "whole" echinoid of the Waccamaw formation, and my third North Carolina species found! This Mellita caroliniana was hiding inside of a matrix-filled Dinocardium robustum also known as the Atlantic Giant Cockle. I discovered it at the last moment before I probably would have accidentally destroyed it, though I was using a less aggressive cleaning method due to a drought in the area. There are a number of other mollusk species in the cockle as well, but I stopped attempting to extract them to keep the matrix stable. The aboral surface is crushed in and the petaloids are a little fractured due to this, with some very small surface pieces missing, but it is still a great specimen! It is currently sitting in a cabinet until I can figure out the best way to preserve it with consolidant, as I am worried it will fall apart if I am not careful. It is likely going to stay in this cockle as well, which I think makes for a good pairing, as well as a demonstration as to how things get buried together in the formation. There is another fragmented specimen in the shell as well, but likely not complete. There is no telling what else is buried in the matrix beneath the sand dollar that I may never unearth; there could be a whole other echinoid under there as far as I know! -
Hi! Sorry if this is out of sudden but recently i came across a landslide and i found this fossil fragments, i have been struggling to identify which animal could they belong, the place is between 2 formations (early pleistocene-late miocene) and while is not in north america, we do share some extinct fauna (Pleistocene-miocene mammals), i hope i can get some hints (some have told me they resemble a rib fragment but i am not sure).

I found this Saturday on a river gravel bank. It's completely mineralized... thin...has an unusual shape and I cannot figure it out. It seems thin like perhaps from a turtle?? But it has such a weird shape plus I don't know if that's an articulated surface on one end... and at the other end... the filler in the center (dark brown) reminds me so much of dentin or cementum which can't be because it's not a tooth. But it looks like that stuff based on what I find here. If it's just a fragment of bone then the interior and exterior are worn to basically match each other in appearance because i can't tell the outside from the inside. Thanks.

From the album: Texas Pleistocene
Camelid tooth Pleistocene Texas Pleistocene fauna is a weakness of mine - I don't know which camelid this is, so if anyone has suggestions for what camels were found in the Texas Pleistocene, please let me know! -
I am finally going through my Florida shark teeth. Most of these are from the Peace River. Hoping to get confirmations and corrections on my tentative IDs. I have numbered the groupings of taxa. Scale is in mm. No. 1: Galeocerdo cuvier? No. 2: Negaprion brevirostris? No. 3: Negaprion brevirostris? No. 4: Charcarhinus spp.? No. 5: Odontaspis taurus? No. 6: Hemipristis serra? No. 7: Galeocerdo aduncus? G. cuvier?

Hello everyone Couple of unusual finds for me from diving in the Cooper River, near Charleston, SC. This river cuts through Oligocene to modern deposits so it can be tough to ID finds. The first looks like a Castoroides sp? broken beaver tooth? The shark tooth has a U shaped root, no serrations on the blade, and has cusps that appear to have a gap between the root and blade. Looks like a cusped P. Benedeni or possibly an upper lateral sand tiger (based on looking through elasmo.com). Doesn't look like an O. Angustidens or A. Grandis to me? I've seen a few cusped Benedeni's identified on the forum and was curious if that is what I found Thanks for looking

So from the title I obviously have no idea what this is. Usually when I pick up something like this I just call it turtle. This does not seem like turtle …. Soft shell or any other that I’ve found. I’m wondering if it could be an osteoderm, but what?

Hello everyone Below are pics of two more items for help with ID. These were found on a dredge spoil island that produces modern to Miocene era fossils. I think both of these are from Ice Age era mammals. The larger grey one has spongy texture and is very heavy dense. It has a few lines running along the sides of it. I don't see Schreger lines or bark like material on it. I don't think it's a tusk, rostrum, or whale jaw bone but it looks like similar to those in appearance. The other smaller brown one is likely a broken piece of proboscid tooth but I'm not sure which part of the tooth or if it may be mammoth, mastodon, or gompotherium. I don't see enamel plates like in mammoth teeth present. Maybe a part of an incisor/tusk? It is much lighter/less dense than the larger one. I've found a few of these before with this shape and apparent Schreger lines. Thanks a bunch for looking

I found these 2 teeth Saturday on a river gravel bank. # 1 The larger one I think is an Equus tooth. It was pretty hard to see because it's covered in this hard matrix. I went to soaking and scraping... but as I got closer to the tooth I had to stop because I noticed it's crushed/broken. I always get a kick out of these. I'd like to think a mammoth stepped on it and did this and then it filled in and hardened over time. I had a nice camelid cervical vertebrae that was crushed on here, but it disappeared when the system was down and never came back. From what I can see without measurements... this looks Equus. It'll stay in this condition to keep it all in place and cause I like the look of it. #2 I'm not sure about this smaller tooth. It doesn't have a stylid. I think it's a M3/m3. I thought it resembled Pleistocene camelid/Llama? I wasn't sure about deer? Then I read about antelope? It's the 1st of these for me so I wasn't sure how to get the best measurements. The chewing surface seems to have one of those center parts offset. Not sure if that mattered. Thanks for your thoughts.

Hello everyone Below are pics of two pretty well preserved toe bones found on dredge spoil islands near Savannah, GA. These islands dredge up modern to Miocene era fossils. My guess is these are from two different medium sized Ice age land mammals. For the sake of description, the one on the left can be called the larger brown toe bone and the one on the right the smaller black toe bone. Thanks for looking. Hopefully there is something diagnostic in appearances to help with ID.

I'm new here, so firstly: Hello! I've been collecting a lot of fossils on the south coast of England this summer, but identifying these 3 has so far eluded me. These were all collected loose on the beach. Hopefully the photos are good enough to give a fair representation.

Hello, does anybody have a clue of what type of fish these scales may belong to? The specimen is part of a fish skin cemented together with sand and pebbles, found on a beach in southern Brazil. Fossils of Pleistocene mammals and marine organisms are commonly found along the beach, but these scales are unlikely those of the largest marine fishes (Micropogonias furnieri and Pogonias cromis) that inhabit this area. Although similar in size, the scales of these species are ctenoid, whereas the fossil scales seem all cycloid, much thicker (~2-3 mm) and formed of stacked laminae.

I found this short, curved, piece of enamel that looks similar to an un-erupted tooth or tusk. The biting surface is rounded, so I can't get a good feel for what it might be.

Hi What kind of mammal is this vertebra and does it come from the Pleistocene? A find from the Vistula River, Poland. Thank you in advance for your help. Best wishes Daniel

Hi I found this piece of bone five years ago. Near the Bat Cave in Jerzmanowice. On the same trip I also found a molar tooth from a cave bear. Was this piece of mammalian bone made by humans? Best wishes Daniel

Hi all My son and I are going through our fossil finds from Florida. We have been looking through multiple books and websites trying to figure out what this tooth is. We think it's from a tapir but would like the opinions of others with more experience. Thanks in advance! Bret & Zach

Hi all My son and I found these three different pieces of enamel/tooth fragments at the NSR. Are these fragments of tooth enamel from a horse? I've looked through some images and think that's what they may be; however, I am new to mammalian fossils. We want to see if anyone can provide some identification/information. Hopefully, the photos remain sequential and do not get jumbled up. Thanks in advance!

Hello everyone! I am interested in fossils and paleontology from many years although my knowledge about ID of vertebrate fossils is very limited. My 11 years old son found these three bones, among little stones in the small river in a past glacious region in Poland. Despite I washed them their collours are without changes as you can see on the photos. The weight seems a bit havier than it "should" be in in the case of more or less new bones. What do you think about them when it comes to their age and possible "owners"? My teenager is very curious but I can't answer at his questions about these bones. Any suggestions will be helpful. Thank you for your time!

Found this mineralized tibia at the Zandmotor beach in the Netherlands. This beach is known for Pleistocene fossils. I don’t know much about rodents, but it was suggested to me that it might be Arvicola amphibius. It is probably a bit too large for mouse or mole. I would love to hear thoughts/suggestions on what it might be.

A couple of weeks ago I went on a trip to the Zandmotor beach in the Netherlands. This beach is mainly known for Pleistocene fossils. I try to go every couple of weeks, but this time I found a couple of really nice fossils - all within the time span of 20-30 minutes. In total I stayed for a couple of hours and found a couple more bone fragments. I would love to share my top 3 with you: The first one is the best fossil I’ve found so far: a piece of upper jaw from a woolly rhino (coelodonta antiquitatis) with the first molar. The second one is a complete radius from an otter (lutra lutra). The final find of the three was a fragment of a radius from either a cave lion (panthera leo spelaea) or a bear (ursus sp.). I still need to compare this one in real life with someone else’s collection. I’m incredibly stoked to have found these beautiful fossils and wanted to share it with you!

Hi everyone! I'm Bastiaan and I love anything (pre)historic. I started searching for (mainly pleistocene) fossils on the Dutch beaches, where I've found a few nice fossils already! My favourite would be a little piece of jaw with a molar from a woolly rhino. Hoping to find more cool stuff in the future and to connect with fellow enthusiasts.

Found this fossil at the Zandmotor beach close to The Hague, the Netherlands. Can anyone ID it for me? I thought it might be turtle shell. However, the pattern on the inside throws me off. It is 2,5 cm wide and a little over 2 cm high.
-
I found this bone yesterday on a river gravel bank. It's completely mineralized. I don't see it as a horse tibia or radius bone. Could it be a horse metacarpal fragment?
