Here's a specimen bought at the gem show back in the days when Moroccan vertebrate stuff was starting to appear at Tucson and other shows. It's from the Kem Kem Beds (Cenomanian), Taouz area, Morocco like that other crocodile-like tooth I showed here several days ago.. This one is just under 2 3/8 inches (59mm) long with long folds/ridges of what appears to be enamel along its length so I think it's a tooth. Some of the folds end part of the way to the tip. There are spots where these folds are chipped revealing a rather smooth layer. It shows wear at the tip. I think it's some kind of crocodile though it seems rather slender for that and I would expect it to be more hollow (view at the root end provided). I'm wondering it actually belongs to some large fish. Maybe it's an odd spine. @Troodon, @LordTrilobite

Hi all. I was was hoping to get help with this one from the community. It was found in-stream near an outcropping of Pittsburg Bluff in Clatsop County, Oregon, and downstream of some Astoria Formation, both marine sediments. I have found mollusks and arthropods in the same collecting area, usually in very hard concretions. To my knowledge no marine vertebrate fossils have been found within the Pittsburg Bluff Group so if it is vertebrate I'm thinking it came down from the Astoria Formation southwest of the area. It looks and feels like bone, and is extremely porous (tongue sticks). Or it may just be a pseudofossil. Either way, thank you for the help.

Any thoughts on the type of teeth found here? Found recently in a Monmouth county creek. One appears to be a crow shark, possibly a shark vertebrate and unsure of the others.

Greetings, First post here, and I'm at a loss trying to identify this (suspected) fossil. I found this a few days ago on Zandmotor beach, in Monster in The Netherlands. On first glance it appears to be a molar, but it looks very different from the Pleistocene material that Zandmotor beach is known for. I've never seen a molar inside a matrix like this one. Some have suggested that it's just a rock, or maybe a piece of limonite. I realise that this specimen looks completely different from other fossil material found at Zandmotor beach, but I'm still positive that this is some kind of fossil. Personally I think it's part of a molar inside a matrix, maybe flint? Someone suggested a sea urchin instead of a molar, which might make sense. Older than Pleistocene considering the level of mineralisation. Picture 1 - 4 show various view of the specimen, with what appears to be part of the crown, and the mold of a root (cast still present at the base of the root (part closest to the crown). Picture 5 shows a second root. Picture 6 - 9 are close-ups of this root, plus a mold of a third root. It appears that some enamel still lines the second root and the inside of the cast. I find it hard to believe that is 'just a rock' or a bit of limonite. If so, it's trying pretty hard to look like something else. What are your views? I would be very grateful if you can help me! PS: Let me know if any additional photographs are needed.

I found this broken end of a long bone several months ago near Houston in the late Pleistocene gravel deposits of the Beaumont and Lissie Formations. Here are some pictures (with each grid on the graphing paper being 1/4 of an inch): I know that it's the end of a tibia because the grooves on the end are shaped to match an astragalus (ankle bone), and that their slanted angle indicates a perissodactyl like a horse, tapir, or rhino rather than an artiodactyl like a bison, pig, deer, or camel. Based on the size of the bone, I think I can pretty easily rule out rhino, which leaves only horse or tapir as a possibility. Now, I've never found a single tapir bone in all the time I've spent hunting in this area, whereas it seems like there's such an overabundance of horse material that I'm literally tripping over their teeth and bones any time I take a step (that and turtle shell fragments)! Needless to say the odds are definitely in favor of horse. What's stumped me is that it seems just too small to be a horse bone - at the very least, not one from an adult anyway. I know that three-toed horses were often smaller than their one-toed cousins, and I've found their teeth before as it's not too uncommon for them to wash down from the older formations north of where I'm hunting, so that's also a possibility. My main problem is that I can't find any reliable measurements online for the distal end of a tapir tibia to compare mine to. So if anyone has any old literature with some helpful information or (even better) pictures, I'd love to see them. Any help is appreciated! @Shellseeker @Harry Pristis @garyc

Hey everybody! I've got two bones that I'm looking to ID, and unfortunately neither of them are complete. However, the good news is that they both have enough diagnostic features that I'm optimistic an ID can be made. Here's the first: This first one is a partial limb bone that I found in a river southwest of Houston. The sediments that make up the river bed are from the Beaumont and Lissie Formations and are predominantly Pleistocene in age (although there is the occasional Pliocene/Miocene material that washes down from further upriver). What stands out to me the most on this bone is the giant foramen that seems to connect to a large hollow cavity near the surface that was broken open when the bone was damaged at some point in the past. I can't tell if this is natural or some sort of drainage port that developed because of a pathology like an abscess. @Harry Pristis has several photos of a pathological alligator metapodial that gave me the idea: Half of an articular facet from one end of the bone is fragmented, but still present. It reminds me of the curvature found on the distal end of horse tibias. Unfortunately, it's a little bit difficult to capture it on camera. The only other distinguishing feature of the bone is its flaky surface. It could just be due to the particular way it was preserved, but I don't think I've ever come across another fossil with a similar texture. Here's the second bone: This second bone seems like it should be much easier to identify as it has two very distinctive articular facets preserved. Three foramina are also present, and enough of the long portion of the bone seems remain that it's general shape can be inferred. When I look at it I'm reminded of a calcaneum but after comparing it to horse calcanea (of which I have two), I can't see a match. The same goes for bison and other artiodactyls, even giant armadillos. I'm not sure what else it could be. As always, any help would be much appreciated! I know there are many people on the forum who are much more knowledgeable when it comes to Pleistocene fossils than me, so I'm once again going to ask for their opinions as well. @Shellseeker @garyc @Lorne Ledger @Harry Pristis

The partial repaired jaw was donated to a geological organization in Phoenix. I thought that I would try to ID it before giving it away probably to a young fossil enthusiast. No provenance is known. Is this an oreodont? Any idea where it came from? First photo of entire rock has a field of view of 4 inches. The second of the teeth is 2.25 inches for a field of view. Thanks, John

Hello, Heres another chunk of interesting-looking bone for which curiosity has finally gotten the best of me. This is a piece I picked up in 2021 on my summer dig at the Hell Creek Formation in Montana. I feel there’s a chance this piece might be identifiable. This piece of bone is bowl-shaped with a strange web-like texturing on the convex side. The edge of the bone which is not broken is rounded and almost flower petal like. There is a set of T-shaped rounded ridges on the concave side. Not the best quality bone either, with significant siderite encrustation being present. I have a few wild ideas about what this might be but want to hear some unbiased opinions. Any ideas and help is much appreciated.

Texas Pleistocene Brazos River Vertebrate Fossil from Fort Bend County
CDiggs posted a topic in Fossil ID
Hi Fossil Forum! I'm hoping for a little help in identifying a fossil I found recently in the Brazos River in Fort Bend County TX. I've tentatively identified it as Pleistocene in age (it's pretty well mineralized) and most likely belonging to a vertebrate mammal but have been rather stumped beyond that. I was initially thinking it could be part of a scapula but I'm now fairly sure its not. At one point I compared it to a skeletal mount of a Pleistocene camel at a local Natural Science museum and was momentarily convinced it was part of the ilium with part of the acetabulum damaged but present, however I'm increasingly doubtful. Hopefully someone with a little more experience will be able to set me straight or at least point me in the right direction. Any help would be greatly appreciated!
