  1. Spinosaur pelvis

    I haven't been able to place it, yet. I figure if I come across someone has familiar knowledge of bones like that, there's a much better chance of recognizing it, than someone just using pics and stuff.
  2. Hello to everybody! I'm kinda new here, but before I start I must say I really love this forum! It has really great vibes and you instantly can tell that this is a good and friendly community! So, I am ziggycardon, I live in Belgium, close to the border of the Netherlands and when we start speaking geologically, I live on the same cretaceous sediments as where the first major Mosasaurus discoveries where done! Unfortunatly I have never been on a fossil hunt myself and everything currently in my collection was bought or given to me. But I hope to change that soon, as I am dying to go hunting myself. Maybe the Chalk sediments 3 km from my home would be a good place to start! For the rest, my job, my major hobby and my other main interest besides fossils are living animals. I currently work as the head of terrarium & aquarium in 3 different pet stores and I have quite a collection of reptiles, amphibians, invertebrates and tropic fish myself. In my spare time I often take my own living animals along with my fossils and other educational natural history material to schools so I can teach kids about nature and it's history and hidden mechanics. For the rest are my other hobbies mainly based around movies and televisions as I collect a lot of stuff drom my favorite franchises like "Lord or the Rings" & "The Hobbit", "Game of Thrones, "Pirates of the Caribbean", ... And I also attent a lot of comic cons and other events related to those franchises. But then this topic! In this topic I will show my collection of fossils (and also minerals, stones and meteorites) as it is right now and then I will highlight each group of fossils bit by bit. I am currently starting with a own specialized fossil room, so ofcourse the progress and end result will also be posted here! And ofcourse when something get's added to my collection, I'll show it here as well. Sometimes a photo of my "special" pets or taxidermy specimens might pop up, but this topic will mainly be about the fossil room and my fossil collection. For the rest, if you have any comments or questions about the collection or about me or about anything, feel free to ask! I'd love to reply!
  3. Here we go, I finally got two nice Sinosauridae indet. teeth (long more or less 8-9 cm). I love the fact that one is pointy and not broken, while the bigger one has the typical ridges along the tooth. What do you think?
  4. I'm having a hard time finding any images of anything other than the outside/side view of a spinosaur pelvic bone. I'm trying to see what the bone looks like in general, but all too many times...WAAAAAAAAAAAAAAAAY too many times I'll spend forever unsuccessfully trying to come across pictures, images, or diagrams that show what a bone looks like from other angles than what you see be looking at the skeleton from generic angles, like this one. In some cases it's not TOO difficult, but even those common bones have areas that you can never see, unless you get totally lucky and happen across it, OR if there's maybe, hopefully some site/database that specifically shows what entire bones look like. I doubt that, but I know there's perfect diagrams floating around on the web, but I can't seem to find any *im just talking about dinos and other extinct animal bones. I'm sure there's plenty of sites with images of every conceivable angle of every bone from humans and common living animals, but I'm not looking for that kind of thing.
  5. I thought I’d post some of my favorite claws from my collection. I’m curious what people think about my ID on one of them and I have no idea what the last one is. ID help with that one would be great! (All measurements are straight line) Spinosaurus hand claw 4 1/2” Kem Kem Beds, Morocco Repairs, but I see no restoration Acheroraptor Temerytorum foot walking claw 1 7/8” Hell Creek Carter County, Montana No repair or restoration (at first). However, the tip broke off during molding and it was lost. 1/16” restoration done to the tip now Two Acheroraptor killing claws. The larger one is 3 1/8” and the smaller is 1 9/16” Hell Creek Powder River County, Montana Large claw has restoration to the top 1/4” of the articulation end and 3/4” to the tip Smaller claw has restoration on 5/8” of the tip Same claw as above, with size perspective Other side... Acheroraptor Temertyorum digit I hallux claw 7/8” Hell Creek Slope County, North Dakota No repair or restoration Acheroraptor Temertyorum hand claw 1 1/4” Hell Creek Powder River County, Montana Restoration to 1/2” of the tip I originally thought this this was a Pachycephalosaurus claw, but Troodon’s posting on TFF makes me now believe it’s Thescelosaurus Hell Creek Powder River County, Montana No repair or restoration Side view.. Troodontid walking foot claw 1 1/16” Hell Creek Wibeaux County, Montana Looks like restoration to 1/4” of the tip Possible Microraptorine hand claw 5/8” Hell Creek Carter County, Montana Small amount of restoration to the top of the articulating end and 1/8” of the tip Same claw... Microraptorine killing claw. Related to Hesperonychus sp. 7/8” Hell Creek South Dakota Restoration to 3/16” of the tip Same claw for size comparison... Curious what people think of this one.. I believe it to be a Troodontid killing claw 3/4” Two Medicine Formation Unfortunately, no locality info on it Looks like the tip was glued back on, but no restoration Other side... Now I have no clue what this could be and I’d love some help. I bought it as a new collector awhile ago with very little knowledge. It was sold as a baby Anzu foot claw and the seller said Black Hills Museum ID’d it. I think it’s actually mammalian. Any thoughts? Size comparison Articulating end (sorry for the poor pics)
  6. My mother's best friend found this I believe somewhere around Fremont County in Wyoming and I've been trying to figure out exactly what it is. I have been told that it is either a Plesiosaurus, myosaurus, or possibly a Spinosaurus, tooth. if anybody has any info on this I appreciate it thank you. I've got more pics if needed
  7. Hi, I came across this fossil Spinosaurus tooth - at least it looks like a real Spinosaurus from what I can tell, but I'm not an expert ... hence my visit here I'm also wondering if it's a single tooth or multiple specimens glued together. I'm worried about the differences in color between the top half and bottom half, but the shape seems to line up pretty nicely, so I'm just not sure. So, is this a real Spinosaurus tooth? And is it a single fossil or a composite? Your help is greatly appreciated! Thanks
  8. Spinosaurus finger and claw

    This looks a little weird to me. Does this seem like the real genuine article to you guys?
  9. New to buying fossils and need some help. My friends birthday is coming up and her favorite dinosaur is a spinosaurus so I bought her two teeth on ebay. The listing says they are authentic "rooted" spinosaurus teeth with no "restore". I have read online that sometimes people will attach cement to the bottom of the teeth and I'm wondering if that's what they did here. I have two weeks to return them so any help would be appreciated. Thanks for the support!
  10. Hello ! This is my second fossil, bought on an small exhibition in France, it's a Tooth of Spino (according the seller). 3,5 inches. I have studied a lot of the old threads on the forum about Spino Tooth, but it's very difficult for me to recognizing a real, a fake, a restored... I paid this piece 138 dollars. What do you think? Especially if there is a lot of restauration ? Is this a nice and authentic piece (for this price of course) ?
  11. Spinosaurus teeth so far...

    So far I have only 2 Spinosaurus teeth in my collection. Their not very impressive by the fact that they’re small with lots of feeding wear on their tips. Hopefully, I can collect more impressive specimens in the future. I added a drawing of the animal to give you a sense of what it looks like. This drawing is also on my Deviantart gallery. One thing I have is that the tooth on the left feels to me more crocodilian like in appearance.
  12. I recently bought a Spinosaurus tooth from a fossil shop on the Rocky Moutains. I noticed this little ridge on both sides of the tooth. I looked at some pictures on the internet and im inclined to beileve that its from the premaxilla. Supposedly the teeth from the premaxilla are pointed with sharp edges on both sides. Could this tooth be one of those? Note that there is feeding wear on the tooth.
  13. I recently purchased this 3.5 inch spinosaurus tooth online, but have some concerns it may be painted. I was told by the previous owner that when checked under microscope, it appeared to have some glue in the cracks, possibly just to keep them from spreading but did not appear to have any full break repairs. However to me, the colour looks too consistent, and the colour leaks into the center on top as though painted. Thoughts?
  14. 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.
  15. 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
  16. Spinosaurus: quadrupedal or bipedal?

    Can anyone give me an answer?
  17. 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.
  18. 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.
  19. 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?
  20. 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.
  21. 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.
  22. 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
  23. 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!
  24. 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.
  25. 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?
