    Partial tooth: Spinosaurid or...?

    Hi all. I know this is not a great tooth by any standard. But to be honest, I do like how it shows its age. Also, it emphasizes how well preserved my other teeth are. And it is nice and chunky! The tooth has lost some of the features to make an accurate ID. Still, it looks Spinosaurid to me. Could it possibly be something else? It is 7 cm long and from the Kem Kem beds. Thanks!

    New Spinosaurid from Portugal

    New species named Iberospinus natarioi. http://cdn.sci-news.com/images/2022/02/image_10573-Iberospinus-natarioi.jpg Link to paper: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0262614

    Spinosaurus Hand Bone

    Seller has this listed as a Spinosaurus hand bone with some repairs, no resto.... just wanted to get some of your guys opinions on it. Do you think it's real? Does it look like there's any restoration?
  5. Name : Ichthyovenator laosensis Age : 130 mya Type : dinosaurs Species : spinosaurid Location : laos Tooth size : 2.7 inches Note : this massive tooth from Ichthyovenator laosensis the spinosaurid from Laos.

    Spinosaurid vertebrae?

    Good evening, these vertebrae are announced as spinosaurid, but it's posible to know just with the centrum preserved? At Kem Kem beds there are a lot of other reptiles so, it's posible to know with incomplete material like these?

    Is this a genuine spinosaurus tooth?

    I bought this tooth last year from a trusted local fossil shop, it was sold to me as an authentic spinosaurus tooth. Is this truly a spinosaurus tooth or is it from a croc (or something else)? Hoping I didnt get scammed.. Also, for future reference, how would I tell the difference between a spino tooth and a croc tooth?
  8. Hello! I saw a jaw fragment for sale from the kem kem beds, it's identified as crocodile. I've seen picsc of crocodile jaws before and that they have like a pitted texture, I don't see that very clearly on this one, but since this is out of my expertise I want to ask you guys who has more knowledge. Could it be something else like a spinosaurid?
  9. https://www.nature.com/articles/s41598-021-97870-8 Two new spinosaurids from the IoW Wessex Formation…making for a total of 3 species including Baryonyx.
  10. The past few weeks at the Tucson Fossil I ran across a few fake Spinosaur claws but also was surprised how many good ones there were on the market. I also understand the issues with online claws so decided to put this topic out to help collectors gain a better understanding of them since they are very expensive. These are my opinions and welcome others since no one person as all the answers. There is no bullet proof approach you can take to insure you have a claw that is not totally fake or composited. There are some things you need to consider. - First try dealing w

    Baryonyx jaw? Tooth?

    This fossil is listed as a Baryonyx tooth with possible jaw underneath. What do members here make of it? Is it possible to tell whether it's a jaw or not alongside the tooth? Formation: Wealden formation, Hastings.
  12. An unusual mid-cervical vertebra belonging to a large spinosaurid from the Cenomanian Kem Kem Group of Morocco is described in this new paper. Here is one more example that continues to fuel the debate that there are multiple Spinosaurids in the Kem Kem Group https://journals.library.ualberta.ca/vamp/index.php/VAMP/article/view/29370 Conclusions from paper: The specimen ROM 65537 represents a new spinosaurid mid-cervical morphotype from the Kem Kem Group of Morocco, with a unique combination of characters not previous
  13. Hello everybody ok, its a little clickbaity, because I'm not talking about a scientific article, as I'm just a random amateur with no scientific background. But I had the chance to publish an article in the most important german fossil magazine, the Steinkern, with around a circulation of 1,500 With good content everybody can write an article there, from amateurs like me to professional paleontologists. It mainly focues on german fossils, like Amonites and other Marine fossils, but is open to all fossil fields. Just use this link to scroll through some magazine

    Kem Kem teeth

    Hi, just working and prep on a box full of Kem Kem material incl. some verts (will post later) and some nice teeth. below are two teeth which I would now label up as Spinosaurid indet. - can you guys confirm this? 1. a small one 2.3cm long:
  15. Came across this site hosted by Christophe Hendrickx a well known theropod Paleontologist. A lot of what he has is already provided in papers but this is the first site completely dedicated to the worldwide group of dinosaurs know as Spinosauridae Pretty cool. This site like many others has a bias toward what paleontologist believes and who he is associated with... so no mention Sigilmassasaurus. I found it interesting but its not gospel just another source of information and opinion. Remember theropods from the Kem Kem especially Spinosaurids are poorly understood and lots of

    Flat elongated Kem Kem bone ID

    I've got this long flat bone from the Kem Kem with a wide base, it was presumably attached to a larger bone. It also seems like it's missing the tip. I thought it might be a small spinosaurid neural spine but it has a weird lump of bone on one side so it seems like it is something else. Is this lump a muscle scar? Or a healed wound? And could this bone be an odd spinosaurid neural spine or is it something entirely else?

    Kem Kem croc jaw fragments ID

    I've got five jaw fragments from the Kem Kem of which I think they are from crocodilians. Any ideas as to what genus or species these belong would be appriciated. 1. No idea what this jaw is from, but my best guess is some crocodilian. 2. I also don't know what this is but also probably some crocodilian. 3. This one has a hard layer of sediment covering it and it's missing the underside of the jaw. It looks a bit like the dented part of a Spinosaurus dentary but it's more likely also crocodilian. 4. Definitely crocodilian, has a typical croc texture (lots of dents). To me i

    Croc or spinosaurid teeth? Kem kem

    Hi! Are these teeth croc or spino teeth? , The curvature and the robustness makes me wonder if they could be croc teeth. Both are from Kem Kem Tooth 1:

    Spinosaur Caudal Vertebra

    A distal caudal vertebra of a Spinosaurid. What's slightly unusual about this vertebra is that it's slightly more slender than most Spinosaurid caudal vertebrae, which have a more square shaped centrum as seen from the lateral side. I am currently uncertain whether this is individual variation or that it might be taxonomically significant.

    Spinosaur Shoulder Blade

    Partial right shoulder blade of a Spinosaurid. Very similar to that of the neotype skeletal reconstruction of Spinosaurus aegyptiacus. There are several large gnaw marks on the lateral side of the bone.
  22. Saw this online, it looks suspicious (but i am no expert) and i thought i would post here for confirmation. It is over 6 and a half inches long.

    Baryonyx tooth

    From the album: Theropod fossils

    Baryonyx tooth Wessex Formation
  24. I've been looking at this 9 cm tooth at an online shop, but it's identified as Suchomimus tenerensis from Hamada gu Guir, Kem Kem, Morocco, and as far as I can gather, Suchomimus has only been found in Niger. I'm very much an amateur but I haven't seen striations on any Spinosaurus teeth I've come across. Any ideas?
