  1. Jaw and teeth ID

    Hi! I am busy going through a collection at a museum. This fossil is unidentified, any ideas. Only have these two pics, might get more tomorrow. I have no details on the specimen, but I'm guessing this specimen is from the Karoo supergroup and Permian in age. Hoping somebody will recognize it, but any help would be appreciated.
  2. I need some help with some I.D.'s. These were both found in some matrix I collected recently in Craven County N.C. The exposure is Eocene Castle Hayne Formation, ?Comfort member. The site produces a few shark and fish teeth, crab claws, echinoids and starfish ossicles. It is a limestone / bryozoan hash. It is possible of course that this stuff is recent or even possibly Pleistocene as I have found pieces of mastodon teeth very close by. First is a small mammal tooth, 4mm long by 2.2 mm wide. Next is a small jaw piece with teeth. I first thought fish, then was thinking lizard. But I really have no idea. The entire section is 10.6 mm long. the teeth are very very small.
  3. Huge spinosaurus jaw?

    Hello! I see for sale this huge jaw (50cm) with some teeth. It’s from Kem Kem. What do you think? Any idea for The correct price? Thank you!
  4. small kem kem jaw sections

    I'm quite interested in these small pieces. Sold as small reptile jaws from Kem Kem. The longer one is approximately 4cm, the shorter one is around 2cm. So very small jaws. I'm guessing, given the circular tooth sockets, they are from a small or juvenile species of crocodile? Or could they be from a type of lizard? If anyone can take a quick look, that would be great. I'm guessing they are much too small to get an actual species, but would be nice to know if croc or lizard. Thanks
  5. Kem Kem crocodile jaw

    I won this a week or so ago on an auction. It was sold as undescribed pseudosuchia with a description "dog-faced crocodile". 2.33 inches long. From Ifzounane Formation, Kem Kem Basin. Description says it has been analyzed by experts as a new species. Nothing comes up for "dog-faced crocodile" other than this very fossil. Anyway, I meant to post it up here to get looked at but forgot about it until now. Anyway, here's some photos. If anyone has any ideas what it could be from, that be great It also came with a pair of nifty X-Ray type photos.
  6. Hello. A while ago I purchased this specimen from a highly reputable and established seller. It's a T-Rex jaw fragment from Lance Creek, Wyoming, and was a surface find (see photos of the original specimen in situ; according to the finder, "the piece in question is at the very bottom left, on top of the edge of the longer bigger bone; the tooth grooves are face-down."). I'm reaching out to Fossil Forum for guidance along the following lines: 1) What part of the jaw is this most likely from? I've been studying images on-line at a cursory level, but I can't find the distinction convex part of the bone that my specimen has (the part that sticks out like a thin ridge). Any thoughts or, even better, photos of comparable specimens? 2) I trust the original seller, but since it was not found as part of a larger Rex specimen, I figured I'd ask for your confirmation: is this almost certainly a T-Rex? I'm fairly knowledgeable regarding teeth, but not mandibles. Thank you all very much in advance; any insight would be deeply appreciated. With best regards and gratitude, Ryan
  7. small skull or jaw bone?

    Im having trouble ID'ing what I believe to be a small skull or jaw bone. it was found in a river bed known to be a popular fossil site. it's a about the size of a strawberry.
  8. Hello, can someone take a look at these and let me know if they are ok? A pair of Mosasaur jaws I quite like. 1st is a Globidens -- from Phosphate Beds. 5.12 inches. Seller says that the tooth is glued, but was found with the jaw. 2nd is Prognathodon -- says it has been glued and has some small fractures filled. Also from Phosphate beds. Many thanks anyone who can help!
  9. Possible Pediomys Jaw at Big Brook?

    My 8 year old daughter found this itty bitty jawbone while sifting at Big Brook in Monmouth County, NJ. It measures a little over a centimeter and includes the tiniest of teeth! Can anyone help me identify it? My first guess based on research is the marsupial pediomys, but I don't have much experience. Thank you for any insight!
  10. Hopefully enough tooth left here for an ID

    North Central Nebraska. Miocene thanks for looking.
  11. Partial Jaw Bovid, Cervid?

    Found on a river gravel bar in southern MN.
  12. Small teeth and jaw section

    This was found in north Central Nebraska, Niobrara River. Miocene @Harry Pristis @Shellseeker @jpc
  13. Spinosaurus jaw?

    It is been sold here--seller gave me permission to post it on the ID thread for a second look. So, if anyone can give me your thoughts, that would be great! It is spinosaurus, from Kem Kem Basin.
  14. Opinions please as to the "original" state of this piece. The seller touts "as found." I have provided the largest image available. Please comment.
  15. Jaw Piece Identification

    Hello all. Going through my pickings from a couple weeks ago. Might be tough but wondering if anyone knows what species this might of come from. Roughly 1.5 in by 2 inch.
  16. Miocene Big Bones Bonanza!

    Got out last week with my boys for a late afternoon trip to Calvert Cliffs to try a new spot. The beach was not very productive, yielding just a few smallish bull and tiger shark teeth. It seemed to have been worked over pretty hard before us. So we quickly turned our attention to a very sizable cliff fall at the tide line. Just looking over the surface, it didn't take long before boy #1 spotted what turned out to be a complete rib fully exposed. (Not 100% sure exactly what from but, I think, porpoise.) It was fragile and ended up coming out in three pieces, but we got the whole thing. On close inspection, it seems it also might have some predation marks. Then, while we were still working on that, just around the corner boy #2 yells out about something big. On the next chunk of cliff fall, also down low, he spotted a really nice piece of whale jaw also totally exposed! We got that out and also recovered the joint, although there is a missing piece in between. Still an awesome find! (The jaw is very solid, so we'll have to learn how to reconstruct the gap and make it one big piece.) We couldn't find any other part of it, unfortunately--we were all hoping for the skull. Just a little while later, on the next big chunk over, another collector pointed out a tiny surface of bone that he generously offered to my boys if they wanted to do the work to get it out. It turned out to be a really cool atlas vert from a porpoise (I think). It was extremely fragile, too, and in a couple of pieces that we'll have to glue together (any tips?), but another neat find. Then, just for good measure, boy #2 digs out a really nice tuna vert. (We added a 2nd, smaller one later.) This was all in maybe a 30-foot stretch. How no other collectors saw any of this stuff--and it was clear many had walked right by it all day--is a mystery. And to top it all off, on the way out with our bone haul, boy #1 spots a sweet croc tooth in the wash. It's funny that we set out to find some big shark teeth, and found almost none, but still ended up with maybe our best fossil trip ever! Enjoy the pics. And if anybody wants to confirm or correct ID's, please feel free.
  17. Hello, a few more Mosasaur jaw pieces that I am interested in. I can't say no to a Mosasaur. It's my fav marine reptile and one of my favorite extinct beasts. 1 -- Eremiasaurus -- from Ouled Abdoun Basin. 2 - Halisaurus -- Ouled Abdoun Basin -- This is my fav of the three. 3 - Prognathodon - Ouled Abdoun Basin. This one looks like the tooth has been repaired? I can't see anything signs that have cropped up on a few past jaws I've posted --- so hopefully, these three are all good and I can pop a bid in for the trio. Thanks for the help, as always.
  18. Kem kem dromaeosauridae jaw?

    Hello! I get this jaw with a tooth from Kem Kem. The tooth seems like abelisaurid or dromaeosauridae. What do you think? Thank you so much!
  19. The seller says it has only a small glued fracture. What do you all think?
  20. Being sold as part of the bottom jaw of a Mosasaur--no species mentioned. From Khourigba, Morocco. 5CM high x 10cm long x 6 cm wide. To me, the jaw section seems legit bone with the photo showing the bone structure and the shattered roots of teeth, but is the whole tooth added or is it actually part of it? Thanks very much.
  21. I know these are often composited, but if anyone can have a look, see how these are, that wpuld be great. I intend to get 1 globidens and one Mosasaurus Anceps. Ancepz I will put on post 2 1 - 15cm long from Benguerir 2 - 12 cm long --the different shading at the root, is that a sign the teeth are added? 3 - 10.5 cm
  22. Sauropod jaw section?

    Being sold as sauropod camarasaur jaw section. From Muffat County, Colorado. 48 x 51mm. Thanks for the help
  23. Spinosaur jaw

    Sold as jaw section. From Kem Kem. 140mm long. Lower jaw. Dpesnt say if teeth are from the jaw or added. Anyone know if ID is correct? Will be nice alongside my spino verts. Thanks
  24. Here is another jaw. It is offered as Halisaurus and is reportedly from Oued Zem of Morocco. It is 10.2" in length. Jaws are a common inquiry here and several members are frequently kind enough to give their experienced opinion of the posted fossils. I would find it interesting and perhaps instructive to the general Forum; if experienced respondents would provide as much detail as they can as to how they formulate their opinion (e.g. common responses such as "teeth may be added," "matrix is not original, etc.") The question I am posing is how are these opinions reached? What clues are utilized? The following photos are the sellers. I realize that any conclusions reached in this section of the Forum are impacted by the quality and completeness of the provided images. Please respond to this fossil with as much "detective" detail as you care to provide. Thanks.
  25. Quick jaw section ID/Oreodont?

    No info on location.
