My husband purchased this landscaping rock in a pallet from a Bath/Bethlehem, PA area supplier about 20 years ago. Most of the supplier’s stones are from Pennsylvania. I’m guessing this is sandstone??? I’ve been staring at this rock for sometime and before I place it back, I wanted to get some opinions if anyone sees any type of tracks on this rock? I feel like my fingers fit in the specimen very nicely. Can’t tell if I’m seeing 3, 4 or 5 “toes” ? Maybe I’m just an imaginative newbie. Thanking anyone in advance who looks at these photos.

Tiny curved, translucent, conic tooth found at calvert cliffs, MD
TRexEliot posted a topic in Fossil ID
Found this today at calvert cliffs. The only things I could think of that it could be were a juvenile porpoise or crocodile tooth. Anyone have any thoughts? -
Hello, I like to buy some crocodile teeth. I am unable to decide between Hamadasuchus, Elosuchus or another species. Location Kem Kem. I have this picture , I hope somebody can help me out. From left to right: 26 mm, 46 mm and 37mm

Hi everyone, I found this at Ramanessin Brook today. I thought it resembled the crocodile scutes that can be found here but I've never seen one in person and I know that concretions can do really tricky things so I'm not sure. Thoughts?

Hello, I've been keeping an eye out for a suchomimus tooth for a while, and saw this trio for sale--I'll get one if it can be confirmed as been suchomimus as opposed to crocodile. 1 - The first two photos is 0.91 Inch 2 - The next two photos is 0.85 inch 3 - The final 3 photos is 1.10 inch All are from Elrhaz formation, Gadoufaoua. Niger. Thanks for the help--if any extra photos are needed, I'll message the seller, see if I can get some. edit: The upload has mixed up the order a bit - the darkest tooth is tooth 1. The lighter one is tooth 3. The one sort of colored halfway betwene them is tooth 2

Very Strange Flat & Thin Cretaceous Fossil. Please Help ID
Backcountryhiker posted a topic in Fossil ID
During one of my hikes exploring the badlands in Central Alberta Canada (Scollard formation) near the Red Deer river I found this strange flat & thin piece of what appears to be fossilized bone. As you can see from the pictures it fans outward and it's quite thin, to me it almost looks similar to a aquatic flipper although I obviously am not sure at all what this could be. My instinct wants to say turtle piece possibly? Any help to ID this cool fossil would be greatly appreciated. Thank you in advance! -
Hi everyone! Long time lurker, first time poster haha. I’m still kind of new to this so sorry if this is a super obvious ID, but I was wondering what kind of tooth this is exactly. I was thinking crocodile, but it seems to have a slightly different shape so I wasn’t sure. I found it at Ginnie Sprints in High Springs on the Santa Fe River in Florida. It’s about 2 1/4” long. Thank you in advance for your help!

Kimmeridgian Clay alligatoroid or Oxford Clay pliosaur tooth
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
Hi everyone, I recently bought this tooth on a whim. It was described as Diplocynodon sp. from the Kimmeridge Clay and reworked into the Albian-age Faringdon Sponge Gravels at the Wicklesham Pit. However, this description is obviously wrong in either species attribution or locality, since Diplocynodon is an alligatoroid genus dating to the Paleocene to middle Miocene, and could therefore not possibly have been found in the Sponge Gravels as Wicklesham Pit. Going by the label that came with the tooth, however, the seller whom I bought the tooth from just copied the information on the label provided by the person they bought the tooth from (I think I recognize the labelling-style, which means I may have a lead to trace the provenance - although that would very much depend on how long records are kept by that other seller and on how long ago the tooth left them). As the tooth isn't rolled, as much of the material form the Sponge Gravels is, and in preservation also doesn't match the buff through orange to deep red colours of most other Kimmeridge Clay material I've seen - whether from Faringdon or elsewhere (mainly Abingdon) - I'm pretty confident this tooth doesn't come from the reworked deposits at Wicklesham Pit. Rather, the state of preservation reminds me of finds from the Oxford Clay. In fact, the root of the tooth has some black deposit on it, that I take to be oxidized pyrite - something I've learned from this thread to be a not uncommon feature of Oxford Clay fossils. Another option as to the tooth's origin is that the tooth could come from Hamstead on the Isle of Wight, where Diplocynodon is known to occur. The dark/black colouration of the tooth and traces of what appears to have been buff-coloured matrix - as opposed to the light grey one of the Oxford Clay - may point in that direction. Though I consider this possibility less likely than the Oxford Clay one for the reasons set out below. Turning to morphology, the tooth doesn't seem to quite match examples of Diplocynodon I've been able to find online. For, while my tooth is densely ornamented with strong striations and exhibits - as far as I can make out - only one possible carina ("possible", as it may just be an apicobasal ridge), other teeth I've seen are mostly smooth/unornamented with what look to be two carinae (although alligatoroid teeth can have anywhere from zero through two carinae and I've also been able to find at least one Diplocynodon-tooth specimen with striations). Moreover, my tooth is conical, which at least rules out the more robust "short but wide" Diplocynodon morphotype. Diplocynodon hantoniensis teeth, Lower Hamstead Beds , Hamstead, Isle of Wight (source) Diplocynodon sp. teeh from the Faluns of Touraine, region of Savigné (source) Diplocynodon hantoniensis from the Eocene deposits at Barton, Hampshire; note the striations This brings us to a closer examination of the features of the tooth's ornamentation, as seen under a microscope. Visible are not just the black deposit on the root and strong and dense striations referred to above, but also what I make out to be remnants of the fossil's original yellow matrix; reticulation of striae; striations stopping close to the base of the tooth, rather than reaching the full apicobasal height; the overall texture of the enamel in between of the striae; and partial cross-section through the tooth enamel. In particular with respect to the cross-section, it may be useful to have a look at the below illustration, figure 4 from McCurry et al. (2019). For, of course it could just be my imagination, but I see greatest similarity with specimen A - that is, the brachauchenine tooth marked as P. interruptus (but see here for a discussion on the validity of this species). Cross-sections through the teeth of A. Polyptycodon interruptus, B. Globidens alabamensis, C. Goniopholis crassidens, D. Spinosaurus aegyptiacus, E. Ichthyosaurus communis, F. Zygorhiza kochii Similarly, if I look at the below diagram of dental ornamentation amongst various clades of marine animal (figure 2, ibid.), I find greatest semblance with tooth D, sauopterygia, pliosauridae indet. (although an argument could be made for A, crocodylomorpha, Deinosuchus rugosus, could be made as well). Phylogenetic distribution and morphological similarity of apicobasal ridges: A. Deinosuchus rugosus; B. Spinosaurus; C. Ichthyosaurus; D. Pliosauridae indet.; E. Globidens alabamensis; F. Hydrurga leptonyx; G. Mammalodontidae indet. I see further comparability in ornamentation when looking at images of the below tooth: As such, I believe that the tooth under discussion here is, in fact, a pliosaur tooth from the Oxford Clay. Moreover, seeing as the density of the striae all round and smooth enamel surface in between, I'm thinking the tooth might belong to Simolestes vorax. However, the traces of yellow matrix make me wonder whether the tooth indeed derives from the Oxford Clay, whereas the few vermiculations visible at the base of the tooth - rare on S. vorax - and the tooth's overall colour make me hesitant whether this might not actually be a Liopleurodon ferox (although I'd think the density of striations would be quite high, in that case; but for comparison with another small L. ferox tooth, see here). As it stands, I guess my questions are: Are the traces of yellow I'm seeing on the tooth indeed remnants of matrix, or could they be dried up glue? Where was the tooth found, what deposits does it derive from? Did it indeed come out for the Kimmeridge Clay, or did it come from either Oxford Clay or Hamstead Beds? Does this correlate with the traces of matrix seen on the tooth? Considering the geological origin of the tooth, is it more likely to be crocodilian or pliosaurian? Is the species attribution correct? That is, if crocodilian, is this indeed a Diplocynodon tooth? And if it were pliosaurian, does it belong to S. vorax or L. ferox? Thanks for your help! @paulgdls @PointyKnight @DE&i @RuMert @Jesuslover340 @caterpillar -
I'll start with the jrf vertebrae which I believe to be a hadrosaur cervical wondering if it is possible to narrow it down to a species if possible? And again anyone who is taking the time to look over these I thank you very much in advance.

Found this at Calvert today. Was about to toss it aside as a rock, but I thought it might be a tooth. Possibly a crocodile tooth or just a rock pretending to be a tooth?

Hey everyone! I'm currently looking for any teeth from the Oxford Clay, especially those of plesiosaurs and teleosauroid crocs. In exchange, I can offer a variety of crocodile teeth from the Jurassic Tiourarén Formation of Niger like (but not limited to) the ones below.

I recently bought this Dyrosaurus skull, it appears to be a juvenile. It has some nose damage and 4 teeth showing on each side. Not being an expert paleontologist but an amateur, I was thinking the teeth look a lot like mosasaur teeth. Are they related? Sue

I just recieved a box with a random assortment of Kem Kem fossils and I was wondering if some of you might help out with some of the ID's 1) A fish scute, Adrianaichthys (Lepidotes) pankowskii would be my guess. 2) Another Adrianaichthys (Lepidotes) pankowskii scale? 3) A small bone, turtle perhaps? 4) Crocodile osteoderm 5) Crocodile osteoderm 6) I often see similar fossil sold as Kem Kem coprolites 7) base of an Onchopristis numides rostrum tooth 8) A large fish vert, could it be Chondrichthyan like Onchopristis or probably just bony fish? 9) A fish vert? 10) Spinosaurid tooth

Since Thanksgiving I'd only been out collecting once. Snow and cold, car repair, work, and other personal matters effectively kept me out of the field. Finally, yesterday I was able to get back out again. I wasn't waiting for ideal conditions and it was COLD!!!!! Temperature only reached 38 degrees and there was little sun for warmth. Winter collecting for me is usually the Cretaceous brooks of Central New Jersey, two hours south of where I live in New York City's northern burbs. Most of the time I go with frankh8147, a great companion, but unfortunately not free that day. He was out collecting Pennsylvanian ferns. Normally we go to Big Brook, but since I was going solo I decided to hit Ramanessin instead. I have a favorite spot I hadn't been to in many months I thought worth checking out again. After I arrived I first I hit a different spot that's closer (and much easier to get to) where I found a hadrosaur tooth last year, a small area that's either hot or not and this time it was not. After a half hour of sifting I decided it wasn't worth staying in that spot so I moved upstream to my favorite area. Getting there was a challenge since there were more downed trees and one I had to crawl under, getting my clothes wet and muddy in the process. Finally got there and started sifting. The first sift turned up what I believe is a small crocodile tooth, 5/8ths of an inch long. It is only my second Cretaceous croc tooth I've ever found and knew already it was going to be my find for the day. A bit later I found a Protocallianassa morton (ghost shrimp) claw, one of my best (includes the bottom pincer). Besides those two finds it was nothing to write home about: The four common shark teeth, Archaeolamna kopeingensis, Cretolamna appendiculata, both mackerel sharks, Scapanorhynchus texanus (goblin shark), and Squalicorax sp. (crow shark), a small shark vert. I picked up a few of damaged goblin shark teeth as giveaways. Also found a small Anomoeodus phaseolus (a pycnodontid shell crushing tooth) and a small Enchodus fang. Also found a partial rodent (beaver) incisor. Most likely recent but could be Pleistocene. I left a bit early because of the cold, but over all this was, after a long hiatus, a fairly nice return. Looking forward to more outings this spring with Frank and then up to New York's Paleozoic sites.

Hi all, I recovered this split tooth from Big Brook park in Monmouth, NJ (late cretaceous). I've checked a couple websites that give information on Big Brook, and I can't conclude either way if it is mosasaur or croc (or similar to a croc). I included close-ups to show enamel, and held it to show the shape of the tooth towards its root. Thanks, Steve

I have here a 1.5" tooth that was sold to me as Sarcosuchus from the Cretaceous of Niger. It's been brought to my attention that this may instead be Suchomimus. After comparing photographs, I believe that Suchomimus is accurate. I'd appreciate more eyes on this. Which one might this be? Thank you, Bellamy

I posted this one alongside a few other teeth, but it didn't get as much traction as I hoped. It's the one I was most curious about, and extremely unusual to me, so I figured posting it individually would be helpful. This is a Moroccan crocodile tooth from Kem Kem. It is serrated, and dagger-shaped, 1.02" long and 0.32" wide. Out of those I have consulted, Troodon proposed Hamadasuchus, though yielded that the dagger-shape is not consistent with those he had seen with those: I've essentially used all of my leads over these few days. If anyone has a different theory, I would appreciate anything to go on. Thank you, Bellamy

I have here a tooth alleged to be Deinosuchus from the Aguja of Brewester County, Texas. It's 1" long. Does it appear to be so? And how would this be differentiated from other crocodile teeth in that formation? Thank you, Bellamy

I have here two teeth identified as Sarcosuchus sp. from Kem Kem, Morocco. They don't look like any Sarcosuchus teeth I've seen. Many here are more knowledgeable than I am about crocodiles. Based on these views, can they be identified as such? These are two different teeth. The first one is 4.2 cm long and nearly 2 cm across the base. The latter is 7 cm and 2.5 cm across the base. Thank you, Bellamy

I have this piece, crocodile?, which I think is a part of a vertebra?. It looks like the are zygapophyses visable and I think the grove should be the neuralcanal. But I am not sure, con someone shine a light on it? Measurements: 70x60x36mm Thank you

I have a 1" dagger-shaped tooth from the Kem Kem. I bought it as a crocodile tooth. The way it's shaped I assumed it was a fish fang, but the enamel looks pretty much like a crocodile's. Here are the only photographs I have access to for the time; is it identifiable? Thank you, Bellamy
