  1. Fossilized vertebra

    Hello everyone. This is my first "identification" post. First and foremost: I purchased this from eBay for a reasonable price. That being said, even though the dealer is reputable and supposedly got it from a reputable source...well we know how that goes. The reason I bought it, is because 1)I can reasonably identify it as fossil. 2) The protruding object that got lodged in its sedimentary matrix, nearest to the transverse process? A tooth? So it was advertised as being disassembled and sold from a Plesiosaur vertebrae, named "Victoria". It was supposedly recovered from the Atlas Mountains of Morocco. Some observations: 1)The tooth-looking object. 2)It's unusually white color 3)The sandy sediment (more like a coastal recovery?) 3)Glue? on the superior part of the fossil?? Question:1)Is there reason to believe it may be from a Plesiosaur. (some from a different forum believe it may be a Miocene mammal? Dolphin?) Please forgive my lack of experience in this field...as I am very new to it. VERY new. LOL. Thanks!
  2. Maybe a new emphasis?!

    Last Sunday I visited a quarry near Zwingelhausen (Germany), where you can find Triassic fossils. It was my second visit there so I am very inexperienced in Triassic fossils. Nevertheless I found some nice fossils (in my eyes ) and I am very satisfied with my haul. I mainly hunted in the "Bonebed", where you can find many bones but they are often damaged or completely destroyed. You need some patience to find some good ones ! I am also a newbie in term of preparing my fossils. I got my first engraving pen (a HW-10) two weeks ago so please excuse my bad preparation results First a picture of the quarry: Then some teeth: Acrodus teeth are very common but sometimes they became big ! This is a 1 cm long one: An unidentified fish tooth (1 cm long): A damaged Nothosaurus tooth (0.5 cm long): And my favourite tooth find until now: This one is very big (2.5 cm long ) I am really in love with this one !
  3. Vertebra from Morocco

    Hello everyone. Saw this vertebra from Morocco and I was wondering what it could belong to. It is approx. 100$. The seller claims it’s Carcharodontosaurus. Could it be Spinosaurus? It is quite big, 13.5 cm. These are all the images I have. Thanks so much for all your help Kind Regards.
  4. Hey everyone. I would like to trade this really nice Spinosaurus Caudal (tail ) vertebra. It is 7,5cm and has some repairs. I would like to trade this fossil for another theropod piece (teeth,bones...) of the same value. (Already have spinosaurus tooth) If you are interested,don’t hesitate to PM me.(You can ask me for more pictures.) Cheers.
  5. Vertebra, possibly Neovenator?

    In a general pm chat with @Haravex I showed him some Isle of Wight vertebrae. With this one Matt wasn’t convinced that I was right on my ID which I was leaning towards juvenile iggy. Now looking at it I agree with him. Let’s get a few more opinions. Brook Bay, Isle of Wight, Lower Cretaceous, Wessex Formation
  6. Hello, This is my 7cm long Spinosaurus Caudal vertebra that I bought from an auction site. It is from Morocco. I have some doubt on the fact that it is from Spinosaurus, if not,what could it be? As you can see,it has been repaired. What do you think? Fingers crossed Regards
  7. Mammoth vertebra?

    I've been watching this vertebra on our favorite auction site and am not quite sure if it's from a mammoth, and neither is the seller, since he's placed a question mark along with it. Could someone more knowledgeable than myself please confirm or deny this? I'm thinking that it may be from some other kind of animal. I'm afraid there's only one photo. It measures 11.5 x 11.3 x 10.5cm.
  8. Don't know what this is

    Can anyone tell me what this is. The story goes it was found in Eastern Montana. I think it is a fossilized vertebra but my friends think it is something else. It is about 3" in diameter. I tried to take photos of both sides. Sorry a couple of them are a bit blurry and it is a friend of mine who has the piece so I don't have it with me and can't retake. Thanks for any light you can shed on this.
  9. Is this a bison vertebra?

    This is from China. Any thoughts on the species? It looks like bison to me, but I'm no expert. Could be equine. Heck, could be a wooly rhino for all I know. Any thoughts from those who know more than I? thanks, Matt
  10. Hi everybody, I've seen this spino vertebra. I don't see any red flag but I'm not a great expert. The price is near 300$ . Thanks
  11. Unidentified Vertebra, Manatee?

    So, I bought this vertebra at a thrift store awhile back, the owner claimed it was found in one of many underwater dives where he would regularly receive fossils from. I'm not sure as to the exact location unfortunately or I would provide more info; with that being said, I don't expect a clear ID. It was definitely found in Florida the owner also said he thought it was a Manatee, but his memory was failing him as he also said which is why I've asked for an ID in the first place. Here are some photos I took, if some more are needed I will try to add more relatively soon. Thanks in advance!
  12. Kem Kem vert process ID

    I obtained this bone a while back, but put it to one side, in the hope that I'd be able to identify it later. It's from Kem Kem and appears to be a process from a vert. In fact, I'm pretty certain it is, because a dealer online has listed this vert, which has a nearly identical process. I'm not so hot on dinosaur anatomy, but I have been looking at photos and diagrams to try and work it out. Would I be right in assuming that the vert above isn't Spinosaurus? I assume it must be dinosaur, because of the size. Thanks in advance.
  13. Kem Kem vertebra

    Hello forum, I came across this at a rock/fossil shop while on a recent road trip. It was labeled as Carcharodontosaurus vertebra from Kem Kem. The shop owner said probably mid-back vertebra. The piece is approximately 12 inches wide and 12 inches across. Any help identifying is greatly appreciated.
  14. Spinosaurus Caudal Vertebra

    This is a picture of my Spinosaurus Caudal vertebra I recently purchased for quite cheap on an auction site. It is 7cm long and 4,5cm high and is from Morocco. As you can see it has some reparation. Hope you like the post!
  15. Wyoming vertebra ID

    A friend wanted to see if you guys could ID this vertebra he found from the hills of Wyoming. He sees a lot of Moose nearby. Thanks!
  16. What is this Vertebra I got

    Hi I would like to identify this vertebra I bought on an auction site. It is from France (Pas-De-Calais). I think it might be from an Ichthyosaurid allthough it is quite big and thick (8,5cm diameter and 4,5cm wide) My second guess is Plesiosaurid. Feel Free to share any details and thank you for leaving comments Thomas
  17. Dino vertebra? North Dakota

    A co-worker just handed me this bone and picture. Wanted to know about it. Found in North Dakota. Thanks! *more info, from western N Dakota Hell Creek formation. Skull around 3 feet
  18. What is this vertebra from?

    Not sure what this one is we are thinking possibly sturgeon not sure .
  19. Another vertebra ID: is it bison?

    This is from China. Any thoughts on the species? It looks like bison to me, but I'm no expert. Could be equine. Heck, could be a wooly rhino for all I know. Any thoughts from those who know more than I?
  20. 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
  21. 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!
  22. 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!
  23. 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?
  24. 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 Abelisaurid dorsal vertebrae From Troodon's collection 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.
