  1. What part of a Mammoth is this?

    I got this off eBay as an impulse purchase. It was described as a mammoth bone from Alaska, but I don't know what bone. What am I looking at? Thanks, Matt
  2. Peace River Vertebra ID

    I found this vertebra in Peace River and I haven't had any luck identifying it. Any ideas would be appreciated!
  3. Whale Verterbra?

    Hello! My older sister just sent me a large fossilized bone. She lives near Raleigh, (Garner, NC) but years ago took her son on various fossil hunting trips with the local club. I know they went hunting around Aurora, NC. The is a vertebra; I know there are whale fossils in the area. She no longer remembers - I do think it is a small whale vertebra! Any other opinions? I am very pleased with it, but would like some input on an identification from a more experienced eye than mine, which is NOT TOO experienced in these matters! Thanks for looking!
  4. Kem Kem Vertebrae ID Thread

    So, lets figure out vertebrae from the Kem Kem beds. As many of you know the Kem Kem beds has a pretty enigmatic palaeo fauna. There is some literature about it, but not a whole lot. Some of it is behind a paywall and much information is pretty scattered. So I got this idea that maybe we could combine our knowledge and information to collectively get a better picture of which bone belongs to which animal, in this case, vertebrae. I know some of you have some fantastic specimens in your collections, if we combine these in this thread we might be able to see some patterns. We probably won't be able to put a genus or species name on each type, but perhaps assigning certain vertebrae to a morphotype might be possible. With that I encourage everyone that has any vertebrae from the Kem Kem beds to share photos of their specimens and post them here so we can use this thread as a sort of library as well as an ID thread that everyone can use to better ID their Kem Kem vertebrae. So please, share your photos! And it might help to number your specimens for easier reference. I will be updating this first post as new information arises with examples to make ID easier. Theropods Spinosaurus aegyptiacus Spinosaurus is known for it's tall neural spines, which are pretty characteristic. Unlike Sigilmassasaurus, Spinosaurus does not have the ventral triangular rough plateau on the centra Spinosaurus cervical vertebrae Spinosaurus dorsal, sacral and caudal vertebrae Sigilmassasaurus brevicollis Sigilmassasaurus is a Spinosaurid that might be closely related to Baryonyx and Suchomimus. It differs from Spinosaurus in that it has a ventral keel on many vertebrae and a triangular rough plateau on the bottom back end. A is Sigilmassasaurus, B is Baryonyx Sigilmassasaurus cervical vertebrae Sigilmassasaurus dorsal vertebrae Indeterminate Spinosaurid vertebrae Not a whole lot has been published yet, so some bones can probably not be ID'd on genus level. Spinosaurid caudal vertebrae From Paleoworld-101's collection Charcharodontosaurids Due to an old paper Sigilmassasaurus vertebrae are sometimes misidentified as Carcharodontosaurid. These vertebrae should be identified on the basis of the original description by Stromer. Carcharodontosaurid cervical vertebrae Abelisaurids examples needed Deltadromeus agilis better examples needed Sauropods Rebbachisaurus garasbae Not a whole lot is known about this titanosaur, as only a few bones have been found. Notice that the vertebrae are very extensively pneumaticised. Rebbachisaurus dorsal vertebrae Unnamed Titanosaurian mid caudal vertebra Crocodiles more examples needed Kemkemia This crocodile is only known by a single terminal caudal vertebra. Kemkemia caudal vertebra Turtles examples needed Pterosaurs Azhdarchids Azhdarchid (probably Alanqa) posterior fragment cervical vertebra Azhdarchid Mid cervical vertebra Sources Spinosaurids https://peerj.com/articles/1323/?utm_source=TrendMD&utm_campaign=PeerJ_TrendMD_1&utm_medium=TrendMD http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0144695 Sauropods Jeffrey A.

  5. What kind of mammal is this vertebra from??

    I found the vertebra at PV beach. the Annulus on the circle part is 1.5 and 1.9 cm What kind of mammal is it from?
  6. Mysterious dinosaur vertebra

    I saw this vert online and liked it so bought it. The seller described it as Dinosaur partial vertebra, ?Iguanodon, from Wealden of Sussex, UK (Early Cretaceous) Does anyone have any ideas what it is, or is the description correct since he was unsure? Thank you
  7. Jurassic vertebra

    Eroded vertebra from North of France. I included a mirrored image. Deposits are late Jurassic, marine and terrestrial. Lenght: about 10 cm. I know this is difficult but any suggestions?
  8. Massive vertebra - whale?

    An acquaintance found this in a Marble Falls (TX) thrift store - provenance otherwise unknown. With help from a capable lab assistant, the following pics were provided, with scale in inches. Might this be from a whale? Hoping we can narrow down the possibilities (and age) for the owner. Thanks in advance for your help!
  9. Ichthyosaur vertebra

    From the album Holzmaden

    A 3 cm long well preserved Ichthyosaur vertebra from the lower Jurassic in Holzmaden. I found it last year and it was prepped by Roger (Ludwigia). The other side: And from another angle:
  10. Finishing identifying some of the kids' finds. This was an awesome vertebra that my daughter dug out in the Hell Creek formation in South Dakota. It was identified for us as a Champsosaurus vertebra. Is there a way to tell *which* vertebra or *where* on the body it came from? Thanks!
  11. Kem Kem Vert

    Hi A couple of weeks ago I aquired some random bone fossils from the Kem Kem beds in southeast Morocco. Among these fossils was also this small, incomplete (dino? crocodile?) vert. I was wondering if it is possible to ID it. The width is about 13cm (5,1 inch) and the height is about 6cm (2.4inch). Taking pictures that show the complex geometry is quite tricky... I hope the pics work for you. As you can see there is some repair. However, as far as I can see all fragments belong to this vertebra (no creative reconstructions).
  12. This Ichthyosaur fossil has just arrived in the mail, i won it at auction. It comes from Whitby in the UK. There are no repairs. On the last photo attached on top of the Vert, is this a rib bone possibly?
  13. Vertebra identification

    Hello all, I am new to the forum and to fossil "hunting" in general. I was hoping one of you could please help me identify a nearly intact vertebra I found recently at Calvert Cliffs (MD). It measures approximately 4.5" superior-inferior, 5" transversely and 5" anterior-posterior. I have several more pictures but am having a difficult time "re-sizing" the photos (as a true amateur would)! If you need more info/pics, please let me know. Thanks in advance for the lesson!
  14. New Jersey Vertebra

    Hey everyone, I found this vert today at ramanessin brook. This site has mostly cretaceous marine fossils but sometimes dinosaur material is found. This vert is very heavy and solid. I'm thinking it's plesiosaur but I'm not 100 percent sure. There is one large hole on the bottom of the vert. One cool thing about this specimen is that there is a bite mark that can be seen in the last picture. I'd love to hear what you all think this is. Thanks!
  15. Raptor vertebra?

    I just recently bought this on a certain auction site (that I've been spending too much time on lately). The seller said it is most likely a raptor caudal vertebra. It was a surface find from the Judith River Formation about 30 miles north of Glasgow, Montana. Is the seller's ID accurate?
  16. Ichthyosaur vertebrae

    From the album Holzmaden

    Three damaged Ichthyosaur vertebrae from the lower Jurassic of Holzmaden. The piece is about 10 cm long and was prepped by Roger (ludwigia): Originally this one was on the same stone as this vertebra: http://www.thefossilforum.com/index.php?/gallery/image/46420-ichthyosaur-vertebra/ The best one:

Originally this one was on the same stone as this vertebra: http://www.thefossilforum.com/index.php?/gallery/image/46428-ichthyosaur-vertebrae/ The other side: And from anther angle: (here you can see how massive it is !)
  18. North Sulphur River fossils

    Another trip to north sulphur river and few more mysteries....Thanks in advance. 1. fish vert? 2. fish vert? (concave on both sides) 3. Stratodus jaw fragment? (1 1/4 inch) 4. coprolite or geo? 5. mystery bone with what appears to be tooth marks?
  19. Not sure if this is man made or some type of vertebra fossil
  20. Information on this vertebra

    Can someone please help me identify this vertebra. It was found in north Mississippi in a creek with shark teeth, coral, shells and other items. It is 9" tall, 5" front to back and 4" wide. I'm not having great success finding someone that can identify this. Or much success uploading the pics so I might have to do it in separate posts. Thank you for any help received.
  21. Kem Kem Vertebra

    Is it possible to ID this vertebra? Thanks ...
  22. Ichthyosaur vertebra

    From the album Marine reptiles

    Ichthyosaur vertebrae from Black Ven, Charmouth, Somerset, U.K.
  23. Unknown Vertebra

    So my friend recently bought a fossil and is unsure as to what exactly it is. We unfortunately don't know the formation or locality, but we are reasonably sure it is some sort of vertebra. Any help would be appreciated.
  24. I haven't been into fossils since I was a child, and I haven't had a good vertebrate zoology class since college. When I found this on a dredge spoil island while on an afternoon boat cruise I knew it was a vertebra, but that's about it. It's heavy like rock. I did a bunch of googling for all the most common things I could think of (Horse, Cow, Whale, Dolphin, Turtle) then I actually started to think it might be a fossil, particularly because the shape of the vert body didn't look like any of the things I was looking at. After a bunch of searching about the concavity/convexity of the articulating surfaces I think it's the vertebral body of a large reptile but with all the interesting processes broken off. So I looked for images of alligator, crocodile etc and I couldn't find anything with such a pronounced concavity/convexity relative to the width/height. Could this be a legit cool dinosaur fossil? Any Ideas?
