  1. Found these and a few other things, including petrified wood, modern bone, old looking mineralized bone and new looking mineralized bone, and brachipods in small chunks of limestone. All found in a streambed in Ames, IA just north of Des Moines. Vertebra is flattened, and I'm fairly sure the thing in the middle is a crushing shark tooth. New to the area, geologic map said pleistocene deposits only. Thank you

    Possible Tooth

    I found this specimen recently and have been perplexed by it for a while. To me it appears to be a tooth, though if it were I don't know from what. I looked at it from under my loop and it does have some small dimples in it, and is made of shiny black material, which is what drew me to that possibility in the first place. It looks similar to teeth I've seen posted on the forum before, especially in the Pennsylvanian shark tooth topics. I did some searching and oddly enough ended up finding images from a ptychotrygon. I don't know what it is exactly, but form the images it has a resemblance to
  3. Hello! I found this in a field in Southern Texas. To me, it looks like a tooth....but now I'm beginning to think I've got tunnel vision. Please help me identify this mysterious rock....or fossil....or tooth. Thanks for any insight!

    Hell Creek Teeth 1-12

    Below are micro teeth from the hell creek formation. Not sure on the ID of these. I have some vague ideas for a couple. Any common or scientific names welcome. 1. Bowfin Cyclurus fragosus tooth? 2. 3. 4. 5. 6. 7.

    Shark tooth for ID

    I thought I posted this earlier, but I don't see it, so I assume it didn't save. My apologies if it's a duplicate! I'm having trouble IDing this tooth, found in Summerville in a creek that has mainly Oligocene but definitely has some Miocene from an overlying lag deposit: Slant height is 23mm, width is 17mm. Here are my thoughts: 1. Sand tiger: curve is consistent with sand tiger, but it doesn't have cusps, a nutrient groove, the "bulge" typically in the center of the root, or the typical root shape. Other sand tigers I've found here

    Thresher tooth?

    Found this tooth in the Summerville area yesterday in a creek that has both Oligocene and Miocene fossils (Miocene comes from a Pleistocene lag deposit). My guess is a thresher of some sort, as I found 3 other threshers there yesterday, but this one looks different than the others (and the 4 or 5 other ones I've found in the last year). I just don't know what else it could be, if not thresher. The root here made me think Paratodus, but it otherwise doesn't look like a benedini: Two more typical threshers found in same creek yesterday (ones I find usu

    Barton Dorset UK unknown?

    Had a walk along Barton beach in Dorset UK and found the normal few shark teeth on the shoreline but any ideas if this is anything or is it just an oddly worn small piece of rock? Length around 5cm. Thank you
  8. Hello I would like to ask opinions about this theropod tooth fossil. The seller says that this tooth is from Aguja Formation and this tooth could be Teratophoneus's tooth. I am not sure whether this is true so if anyone has opinion about this tooth, I would be glad to hear it!

    SE Texas - modern pig/hog tooth?

    I found this today. It has a lot of river wear to it and even the chewing surface is pretty worn. Are those cavities?? I suspect pig or hog. It's 1" across.

    The large item on the right. I have no idea what I found, I was thinking a tooth but not sure! Please help!

    (shark?) Tooth

    Some kind of tiny shark-like tooth. Found on Central Oregon Coast in a chunk of mudstone or similar.

    Tooth or tooth looking stone?

    I'm really hoping this isn't just another stone... and I'd love to say where exactly I found it but I can't for the life of me, remember! I just know it was in the peak district. The shape really stood out for me and I'm finding it difficult to believe it's been geologically formed. Let me down gently... cheers guys and girls!

    Mosasaurus hoffmanni tooth?

    Hello, I have another mosasaur tooth ID question. This is listed as Mosasaurus beaugei from Kem Kem Morocco, on the small side at just over 4.1 cm. Based on what I recall @Praefectus said, is it possible this is actually a M. hoffmanni? It has very few, prominent facets, which are apparently diagnostic to hoffmanni rather than beaugei? @pachy-pleuro-whatnot-odon Sadly the tooth doesn't seem in the best shape though. Thanks!
  14. Hi All, I'm new to this forum and thought I'd send over images of my theropod teeth plus one extremely impressive sauropod from Madagascar. Hope you like them! Paul
  15. Items collected during Nov 5th 2022 at Ladonia Fossil Park near Ladonia Texas. Any help with identification would be much appreciated, as well as descriptions of the key traits to hone in on to rule out other possibilities. Trying to learn what I can. Many thanks!
  16. My buddies and I recently went on a trip to Andalusia Alabama. We got an airbnb near the point a dam. We retrieved a few teeth that we believe are some goblin shark teeth and a auriculatus shark tooth, perhaps. If anybody has any insight please feel free to comment. I have some more pictures that I will upload from one other trip that I did by myself.
  17. Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!

    Is this a Sperm Whale tooth ?

    Hi, Thank you all so much for your vast expertise. I have been a novice member for some months and have learnt so much from browsing around this forum. It is fascinating and l can happily spend hours here. I only have a few fossils , all common and easily identified. But l recently aquired this tooth which with the help of information on this forum l am tentatively labelling as a Sperm Whale tooth (Pygmy ?) It has horizontal banding and a hollow base which l think are characteristics? Unfortunately l have no information asto its region of origin. But it does have an old invent

    Is this a pliosaur tooth? Or plesiosaur/polycotylid? Turonian, Upper Cretaceous, Asfla, Goulmima, El Rachidia, Morrocco.
  21. My brother found this tooth years ago at big brook. It looks reptilian to me, and seems to have the root preserved as well.

    Is this a dasyatid tooth?

    Is this a dasyatid tooth? It seems different from the others I'm finding in this micro matrix. Grid lines 1mm spaced.
  23. We recently picked up a landscaping and grass cutting job at a big office for a boat company with several warehouses and an office, etc. I noticed near one of their storage shed was reddish dirt, sandy and full of rocks, typical of the creeks of Northern and Central Louisiana or Mississippi, probably hauled in from 100 miles away. I noticed this and said to myself to keep my eyes out, might find a fossil or arrowhead. Sure enough, this was just barely sticking out. At first I thought it was a cow but realized it was way too big. It also passed the fire and sound test. From looking at others on
  24. Hello, Just want to ask for some opinions on whether this is a Smilodon incisor and how one would be able to identify it as such since it’s in pretty worn condition, it seems more likely that it could be either dire wolf or bear and that the “Smilodon name” is just to get more attention and money for the fossil? Thanks in advance, appreciate any help!

    Tooth Tuesday

    Should probably post more in this forum section since we’re doing multiple hikes a week but here’s a couple cool finds from today out in the dinosaur park formation. The wildfires here in Alberta have been raging wild, the smoke finally made it this far south. Here’s a couple nice tyrannosaur teeth, thankfully we found the big one when we did, would have exploded soon. It’s probably around 2.5 inches haven’t measured it yet.
