  1. I apologize for the multiple posts. But so many interesting things I want to buy, and literature in our language is not always enough, as well as people who specialize in dinosaurs. We have a lot of specialists in unvertebrates, marine reptiles and the ice period fauna. But with beds of other countries is not very. Is it really a dinosaur caprolit? The seller writes that you can see the bony inclusions.
  2. Although the paper is paywalled the abstract provides some interesting insights The hypothesized aquatic habits of Spinosaurus have been called into question, and the distribution of aquatic habits within Spinosauridae remain unclear. New spinosaurid specimens from the Kem Kem beds of Morocco reveal aquatic adaptations in the cranium. 1) Elevated orbits and bending of the frontals placed the eyes atop the skull, as in semiaquatic animals such as crocodiles and hippos. 2) Two morphologies are present, a smaller morph characterized by narrow, triangular frontals, and a larger morph characterized by broad, subrectangular frontals overlapping the prefrontals. The two morphs suggest two distinct spinosaurine taxa, and are tentatively referred to the spinosaurines Spinosaurus cf. aegyptiacus and Sigilmassasaurus brevicollis, respectively Another interesting point in the abstract: The appearance of giant semiaquatic dinosaurs may have followed the disappearance of giant pholidosaurid crocodylomorphs, suggesting that the extinction of large crocodylomorphs was associated with the rise of dinosaurs as apex predators in the freshwater ecosystem in North Africa. https://www.sciencedirect.com/science/article/pii/S0195667117303427 Aquatic adaptation in the skull of carnivorous dinosaurs (Theropoda: Spinosauridae) and the evolution of aquatic habits in spinosaurus Thomas M.S.Arden, Catherine G.Klein, SamirZouhri, Nicholas R.Longrich From outline images frontals are shown. @LordTrilobite
  3. Spinosaurus: quadrupedal or bipedal?

    Can anyone give me an answer?
  4. This morning I noticed a Spinosaur foot claw for sale and on the surface looked like a very good purchase. Closer examination revealed a couple of concerns. First the proximal end of the claw is all weathered away to the point that diagnostic features on the ventral surface are missing. Second the seller claims no resto but I'm very concerned about the tip. There is a change in texture and color in the area I have marked. Caution.
  5. Dinosaur claws from Kem Kem

    Hola amigos, estoy interesado en comprar algunas garras de dinosaurios de Kem kem. Te muestro las garras que me han ofrecido para que me digas a qué especies pertenecen y si las ves muy restauradas. Thank you so much. Translation Hello friends, I'm interested in buying some dinosaur claws from Kem kem. I show you the claws they have offered me to tell me what species they belong to and if you see them very restored. Thank you so much.
  6. Seller claims to have secured this in an estate sale. It’s on the pricey side. For me, it’s difficult to see any difference between this and an average spinosaurus tooth. The fossil is from moroccan sahara, says there is civil war in the tenere desert, and therefore collecting there is illegal due to current regulations. Thoughts?
  7. Hello all. I’m very, VERY new to the world of fossils and fossil collecting as a whole, but it’s something I’d really love to get into. I’d just like to ask for some opinions on the authenticity of these Spinosaurus teeth. I’m interested in purchasing, but would like some thoughts from people who actually know a thing or two about this stuff! I could not find that much info on the seller so I’m a bit cautious. Thank you so much for looking and considering.
  8. Spinosaurus sail?

    Ok, so this is supposed to be a spinosaurus vert, one with part of the sail. At first glance it seems perfect, but upon further study, while trying to place it on spinosaurus skeletons, it doesn't seem to match any exactly. For one thing, spinosaurus sails, at least in the relatively insignificant amount of individuals on display, sail bones that don't go any higher than this one(it appears this is a fully intact sail vert), don't seem to get as wide. And the ones that do, then continue up and get thinner. There ARE similar shaped "sail" bones, at the transition to the neck, and tail, but those aren't as tall as this one. The main bone itself appears to be from the tail, or rear part of the sail, but....well, anywhere that one part of the bone fits well, doesnt seem to match the rest of it very well. Sadly I can't find any good images of many of each type of vert, and anywhere that has good close up views of verts, only have 1 or 2 of any type, which isn't good enough to come to any sufficient conclusions. spinosaur fossils(specifically verts), seem to be something they work with a lot, so I would be very surprised if along with all the other spinosaurus verts they get in, they would end up with the sail spine of some other animal. And if somehow so, then not realizing it.
  9. Some paint added

    Aloha. here are two 3d printed models I showed before. The Turtle is selfmade, the Spino not so. I took the time to paint them and quite like the result. Pondered to give the Spino the reddish colour one often sees with fossils from kem kem, but decided rather to colour the "matrix", which is in fact a piece of treebark. Best regards, Jan
  10. Hi all, I'm a new member here, just joined not long ago and I have been wanting to purchase a Spinosaurus jaw. I was wondering if any of you can tell if it is real or fake? I've also been wanting to buy Theropod complete foot (any species), anyone know some reputable sellers? I just want the toes, claws etc. Thanks!
  11. My eyes are not so good when it comes to Kem Kem material. What do you guys think of this vertebrae? Is it indeed Spinosauridae? It looks to me like the process has been reworked, or repaired.
  12. 70% real spinosaurus skull?

    Here is a fossil I just saw on an auction site. Apparently the Spinosaurus skull is 70% fossil. Is this for real?
  13. Spinosaurus jaw?

    Hi all. I have a thread in another section of the forum about this, but figured this may also be a relevant place to make a post. I've had some interesting and helpful opinions so far, but would like more if possible to help decide it and educate myself and maybe others in the process! I'm looking to purchase a piece of what is labelled as Spinosaurus jaw. I've found what appears to be a small section, being sold by an apparently reputable business. I know from my own research that crocodile jaws are often sold as Spinosaurus jaws, but there are some stark differences between the two in anatomy and appearance. Below are some photos of the jaw, what do you think? Spinosaurus or Crocodile? I know that the teeth are added to the piece, as with virtually all Spino jaws I've seen. Generally it's only unerupted teeth that are present when found if at all. All opinions are respected, please provide some reasoning for either way so that we can educate everyone in the process.
  14. Hi all. I'm looking to buy a Spinosaurus jaw, or at least a piece of one. I know that a lot of crocodile jaws are fashioned and fitted with teeth to resemble one, with some distinct differences to the structure and composition of the bone. This one is being sold by a reputable seller as authentic with no repair/restoration (though I'm presuming the teeth have been added). It appears to be all good from my limited experience and looks like it should, both in structure and composition. I was just hoping to get some more opinions from all you lovely people on here, as I'm not overly knowledgeable on these. This one is small and approx 4 inches long x 3 inches high. Many thanks for any input. Found:- Tegana Formation, Aptian, Cretaceous, Kem Kem Basin, Morocco, North Africa. Age:- 100 Million Years Old.
  15. Location: Morocco Kem Kem Beds To often Crocodile jaws are composited with Spinosaurid teeth and sold as Spinosaurus jaws. So the purpose of this topic is to show the diagnostic features of Spinosaurid jaws First its extremely rare that any jaw from this region contains functional teeth. Germ/unerupted teeth are more common but those are typically well into the tooth cavity and not protuding above the jaw line. So its highly probable that those you see sold with teeth are composited. We currently do not know if there is a variation between the jaws of the different Spinosaurids described or yet to be discovered in this region so there could be some difference between them but the general characteristics should be similar. Here is a composite skull in private hands and paleontologist Cristophe Hendrickx drawing of that skull Dentary: This is Stromers original plate. 1) You can see the variation in the lateral (side) view of jaw. A very wide anterior end and more V shaped toward the hinge. So jaw sections that you see sold which are straight across are probably crocodile. 2) The teeth are also not positioned in a straight line, and not always next to one another. 3) The most telling feature is the lip on the labial side. It should be present across the entire length of the jaw 4) Broken dentary jaw sections being sold should wide not narrow like croc's Closeup of Lip Close up of germ/unerupted teeth Premaxillary/Maxillary Much more robust than dentary however the lip feature is still present but on the lingual side. Very wide in lateral view. http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0144695 dal Sasso, C.; Maganuco, S.; Buffetaut, E.; Mendez, M.A. (2005).

  16. This is my 8.9 cm. (3.5 in.) Spinosaurus tooth, which actually is in surprisingly great shape! (apart from cracks caused by clumsy past owners) However, it is curved (~0.5cm in one direction, and ~0.4 cm off to the side of the previous curve). This leaves me to wonder- how did this happen? My theory is that this Spinosaur either had something HUGE stuck between its teeth that caused them to deform as it grew older; or that a sideways tooth interfered with the normal growth of this tooth, and caused it to grow sideways (to make room for the wayside tooth). The latter is actually very common in humans! (This is why many of us as teenagers had braces, as to prevent our teeth from growing in every direction). I also prefer the last argument (I know, I argue with my self, haha...) because there is a long 3 cm indentation along the side of the tooth, which is exactly where the tooth would have interfered with the room of another tooth. The indentation is likely the blade end of another tooth which was in place when the dinosaur was still alive. The mark is visible on the right side of the tooth in the last image. I just that this was a very unique specimen that I wanted to share with the world, especially because mine is in such good shape for a tooth with almost 6 cm of intact tip enamel, and another three centimeters of root. Does anyone else have some pathological (deformed) fossil teeth they would like to share? Sounds cool! -Fossil sniper
  17. Giant Spino tooth?

    Hi all, In the market of Middelburg, I saw this big fossil for sale. The stand owners say it is a Spinosaurus tooth from the Tenere desert, from the Cretaceous (when precisely they don't know). But I am not very sure of this ID, because I am not seeing anything that really looks like enamel. Also, it is HUGE! Some of the photos show a 10c (Euro) coin or my hand for size indication... It's approximately 18cm from tip to tip. I don't know much about spino teeth, but isn't that a tad too big? So, what exactly is it? Is it indeed a giant spino tooth? If yes, is this a normal size for it to reach? If it isn't, what is it then? And how much of it is real (in case part of it is fake)? Unfortunately, I didn't buy the fossil, so I can't give any extra pictures. I am curious to see what your answers are! Best regards, Max
  18. Our favorite auction sight has a Spinosaurus aegypticus skull listed from a seller in France. The seller lists it as being "real" and "70% complete." I was under the impression that there have been no complete spino skulls found? If you go onto the sellers regular website he also has a full spino skeleton that he says is the most complete specimen ever found.
  19. I saw this tooth now the question is if the whole root is real..? I think it's a composite of two roots one is part of the tooth the other one glued on.
  20. 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.
  21. Dinosaur Postures

    After the satisfying outcome of my sloth-experiment (changing geoworld megatherium to Thalassocnus) I took another look at some older dinosaur models. Sauropoda- Giraffatitan: "Edutoys Brachiosaurus", added teeth and one cervical vertebra to give him a more erect pose, Changed cervical ribs from medial "monorib". changed leg pose. Thyreophora- Stegosaurus: Glencoe models , changed tail and thagomizer to more modern pose Ceratopsia- Triceratops: Kaiyodo "Wild rush" gave him a treetrunk to look over. Ornithopoda- Parasaurolophus: Geoworld, drilled out intercostal plastik. painted it. Theropoda- Spinosaurus: had it 3d printed. I wonder if I should give it a swimming pose, what do you think?
  22. So a seller was offering me these teeth, the biggest is about 13,5cm long. I am interested in the long one wich looks like it is fully rooted. But the question is is it a composit?
  23. So I've recently decided to start collecting fossils and such And for my first fossil i decided I would like a spinosaurus tooth (as the spinosaurus had been a favourite of mine since around the age of 10) The tooth wasn't super expensive but I inquired the seller about it and asked if it was real. They said it was basically. Anyhow, I got the tooth and was wondering if you guys could give me some insight on wether it is genuine or not.
  24. Hi all! Im beginner collector, and about to pull the trigger on one meg tooth. Here are some pictures I'm deciding from, please give your thoughts, and help with a decision! If you like a tooth please comment on it, if you see one maybe I should avoid, please do the same. I know it's all a matter of preference, but please give your thoughts.

  25. Is the white part down there peeled of enamel or the root. It also looks like a port of the tooth was cut or worn down.
