Four weird little pieces from Gainesville fossil hunting. Guess for 1 is maybe turtle? 2 is very dark and was hard to capture the detail on top even with a dslr and flash, maybe a fish part? The bottom two both appear to be some type of teeth to me, whether that’s crocodilians or cetacean I’m not sure. I’m not even certain they’re identifiable!

Hi, all! Found this in Green Mill Run last week. Not sure who used to own this one. Doesn’t look exactly like a croc to me. Root seems weird. Thanks!

Hey everyone, new here, but hoping I’ve come to the right place! My family just got back from tooth hunting on shark tooth island and found these too and wondered how we could confirm what they are and if they’re just ordinary or could be extraordinary!

I have not been out hunting enough, which has me looking at old TFF threads. I posted this canine 5 years ago in FosslID , but did not get much feedback and it faded without me learning much about it. Originally, I thought Alligator, because of the hollow root. but it did not have a horizontal edge between enamel and root, and the root was not an oval shape. Then I considered Dire wolf, because of the shape of the enamel, and the shaped carina down the side. I wondered at that time if the tooth was unerupted. I have never found/identified a Dire Wolf fossil from this site. Finally, because of the serrations ??, I thought Sabercat. The serrations are not clear, the root is oval... Please tell me what you think it is, and what you think it is not... I'd rather not have another 5 years go by... wondering.

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

Found on Holden Beach, North Carolina. If you need certain measurements let me know, thank you.

Hello I've been "fossil dormant" for quite a while, but was on the beach yesterday and found these (the recent storms have churned/coughed up some new layers I think) the start tooth may be hard to ID without any of the bourlette, but I can tell you that it has absolutely no serrations - perfectly smooth cutting edges. Mako? As for the small conical tooth, I think it is alligator, but I'm not sure if alligator teeth have distinct sharp crease from tip to base on opposite sides like this tooth does. Thanks for any advice

Can anyone identify this? It was found on a dirt road in SE Georgia near the coast. Dredgings from the shipping channel are used to fortify dirt roads. I know it's difficult to do using pictures alone so I'll include as many clear shots as possible.

Here’s a chunk of crocogator I found on the Brazos River in SE Texas. It doesn’t look like the typical osteoderms that are found . I’m not sure if there’s enough here to identify a specific bone…

Here I have a prett rare a nicely preserved Deinosuchus Riograndensis tooth from the Bufftown Formation, Alabama. Looking for great quality theropod teeth from the KemKem region, preferably Carcharodontosaurus. Open for other dinosaur teeth as well. Just hit me up!

Hello! I am wondering how much this alligator jaw is worth, It is 6 inches and its from the peace river formation ~5 million years old. I thas 5 teeth and 13 sockets (including the ones with teeth) Thank you!

Hi, Just found this tooth in the Cape Fear River of Wilmingnton, NC. I think it’s either a prehistoric alligator or crocodile. Trying to identify its species, help would be appreciated. Thanks!

Found these in Maryland at Flag Ponds State Park which is known for it's abundance of marine fossils. I think the lighter colored piece is some sort of reptile (maybe alligator or turtle) skin? The black piece seems to be a some sort of fossilized reptile skin? Seeking expertise or thoughts, thanks!

Here is my newest addition to the collection. A pretty decently sized Deinosuchus riograndensis tooth from the Aguja formation in Texas. The colors and quality on this tooth is actually insane, do not get much better than that.

I've been trying to do some research about actual gator scutes not ostoderms that we call scutes. I know that Dino skin can be found so can croc also? Would love to hear about this subject and see some great photos if possible too please!

Found on the shores of Holden Beach, North Carolina. If you need measurements of anything let me know, thanks.

This is my final ID question. I promise. Until the next one. I'm thinking an alligator tooth with a very worn crown. Tom

I found this fossil in a pallet of rocks I got for landscaping. The rock came out of the Arkansas river. When you stick your tongue to it, it sticks as a bone would. I think it looks like reptilian skin. Could anybody help me out?

I just posted some colorful small shark teeth I found yesterday, but also went out Saturday. I had a number of finds which were small and I was not certain of their identification... 1) An Epiphysis, which I think is a long bone "cap" for a juvenile mammal. Which bone? 2.) A possible claw... Could this be bear ? 3) Looks like a Carpal or Tarsal, but not one that I have seen. VERY light in weight. 4) An odd Alligator or Crocodile Osteoderm. On the left of the 2nd photo, there is a flat section on the left edge, and then the increased slope to the center. possibly imagination, but it seems different from the average gator osteoderm. 5) Finally , a very small fossil and definitely unknown to me Any comments and suggestions greatly appreciated... Jack

I bought this tooth together with two other teeth as ''Smilodon teeth'' last year. Thanks to this forum, I found out that the other two teeth are actually Enchodus teeth! I think this one might be something else. Someone on Reddit told me that it could be a crocodile tooth, but I have little to no knowledge about crocodile teeth. I understand if it's difficult to identify, because the tooth isn't complete. It's 2cm and the seller couldn't give me information about where this was found. Any help is appreciated, thanks!

http://www.thefossilforum.com/index.php?/topic/82717-kem-kem-bone/ This link above has an interesting picture of an Alligator shoulder blade, that I thought a little similar. Not broken, a lot of detail... How come this one is difficult? ....

Hello I am considering getting this set of Deinosuchus teeth. 37 teeth. They are from Chattahoochee River region, Bullock County, Alabama, USA. With the formation given as Ripley Now, looking online, it doesn't show Deinosuchus as being from there. But I do see teeth sold elsewhere as Deinosuchus from the Chattahoochee River. They were also apparently found in a dive along with David. R Scwimmer, who wrote a book on Deinosuchus. The largest is 27mm the smallest 10mm. If someone can take a look, that would be great. fossil_deinosuchus_crocodile_t_1594656235_74263265_progressive.jfif

We found this tooth near 48th Ave in Myrtle Beach on Jan. 20, 2022. We have never found a curved tooth before. Any idea what it might be? We were thinking alligator or mosasaur. Thanks! Deb and Wayne Lien

Got out on the river yesterday for what turned out to be a productive day. It was a chilly morning so the wetsuit was a necessity. Even if the air temp is warmer the water stays cold throughout the day. I returned to a gravel bed I found earlier in the week and got right down to digging and sifting. Every clean out of the sifter provided a good number of various small shark teeth. Tiger, Sand Tiger, Snaggle Tooth were abundant. A few small partial megs and even a baby Mako made an appearance. Below is a picture of the best of the shark teeth along with an alligator tooth and what I believe is probably a modern pig. left side = Tiger, Sand Tiger, baby Mako and the possible pig. right side = Snaggle tooth, Lemon and Alligator. A couple of close ups of the Alligator: And a couple of close ups of what I think is the pig. If it may be something else please chime in- These finds and the additional bag full of small shark teeth would have been a good day. I was lucky and also came up with a variety of other finds pictured below- Left side- 3 Glyptodont Osteoderms, (the top one from the tail),1 Giant Armadillo Osteoderm. Right side- 5 Turtle/Tortoise leg spurs, 2deer antler bases, 2 gar fish scales, 1 Sting Ray scute, 1 Tilly bone. A couple of close ups of the tail osteoderm- The following large pieces appear to be giant tortoise shell fragments the biggest measures 5.75” x 3.5”. I have at least 5 additional bones I’m working to ID. A possible tiny astragalus, seismoid or maybe magnum, a small medial phalange, a small distal phalange and another possible astragalus or maybe cuboid. I’ll be posting the ones I can’t figure out in the ID section if I hit a dead end. Definitely worth the chilly water on an otherwise perfect day on the river. Looking forward to getting back out there as soon as possible!

Various teeth from Eagle Ford, Cretaceous, I'm a long way from recognizing teeth since I don't find them often so appreciate the education. My guess for first one would be Mako, it also looks very much like the tiny one in #3, second one I'm not sure at all and wondering what made all the marks on it? Last group I think there's an Echnodus, and cone shaped one looks like alligator or it's just wishful thinking.
