  1. 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). New information on the skull of the enigmatic theropod Spinosaurus with remarks on its sizes and affinities. Journal of Vertebrate Paleontology. 25 (4): 888–896. doi:10.1671/0272-4634(2005)025[0888:NIOTSO]2.0.CO;2 Maxilla for sale with composite teeth
  2. 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
  3. 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
  4. 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.
  5. 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.
  6. 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.
  7. 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?
  8. 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?
  9. 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.
  10. 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!

  11. 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.
  12. These are two composited Spinosaurus teeth I found at a convention. Feel Free to post what you found or have.
  13. Posted here are some very nice fossils for collectors just be aware that the descriptions might not be as advertised. Seller calls this a Pterosaur claw, I'm not sure what it belongs to but nothing is published to support his claim Seller list this as a superb Spinosaurus phalanx toe bone. Looks more like a hand bone, carpal or metacarpal. Also we do not know if it comes from the species Spinosaurus better described as Spinosaurid indet. Seller is describing this as a Spinosaurus caudal vertebra. Spino caudal vertebrae are typically more box shaped so I doubt it's from one. Not certain what's it's from. Seller is offering a very nice upper and lower jaw bone from the Pterosaur Alanqa saharica. I question if these are associated and if either are lowers jaw sections.. Ibrahim's reconstructed jaw shows the mandible as being much thinner than the upper and more like the offering. I also will add that isolated upper jaws may be hard to identify to a specific species and are better described as Azhdarchoid indet. since along with Alanqa the new species Xericeps may have similar uppers but it's currently unknown. Seller is offering this pair of bones as a Spinosaurus Phalanx bone and Claw. Unfortunately the phalanx is a hand bone, carpal and not associated with the claw. The claw may belong to one of the Spinosaurid's but without a ventral view it's uncertain its one. Offering for a large toe bone from a Spinosaurus. Looks more like a Carpal from an unknown Spinosaurid. Offering big money for this Spinosaurus complete foot. Unfortunately there are many things wrong with this foot. Most of the phalanx don't fit their positions and may not be Spinosaurid. The claws are undersized for the foot and cannot determine if they belong to a Spinosaurid with the photos that are provided. A foot should look like this Remind buyers that all teeth offered as Spinosaurus may not belong to that species but one of the other Spinosaurids that may be present in that fauna either currently described or yet to be identified
  14. 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
  15. Fossil Stands

    I wasn't sure where to post this thread, but I have a few fossils that I'd like to either buy or build stands for. I have seen lots of display stands (looks like a wire frame and a metal base) for carch teeth, and mosasaur teeth- that's what I'm looking for but I cant seem to find any for sale on the internet! Not interested in the little plastic megalodon stands, I'm looking specifically for a small wire frame stand where the tooth is held in place by its natural taper. Looking specifically for spinosaurus, carch, and mosasaur tooth stands. Any help would be greatly appreciated, thank you! N
  16. I had posted these on my collection gallery - and one or 2 people thought perhaps these were NOT rebbachisaurus teeth; rather Spinosaurus. I would like to classify them properly - SO.... looking for opinions! I want to know if corrections are needed. (And I am NOW looking for a GOOD rebbachisaurus tooth online). The dealer I got this from is not a "dealer" in fossils as far as I can tell.... but I will avoid him in the future, I think!
  17. Hey guys, I have the option of getting one of these 2 rooted Spinosaurus teeth, but unsure which one to go with... One is over 6", the other over 4.75"... I like the look of the shorter one better and it matches my other Spino teeth nicely, but is the big one a really nice specimen??? Opinions??
  18. 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
  19. 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.
  20. 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!
  21. Hello, Saw this posted the other day and its a bad fake, buyers beware.
  22. 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 with what I call preferred Moroccan merchants, those are typically found at big shows and a few have online or FB sites, ones that specialize in Moroccan material are the best. They typically know what to look for and can point out issues with claws. Makes life a bit harder to get one but you want a good claw don't you. This does not take you off the hook its still YOUR responsibility to know what you are buying. - Unless you are an expert never buy one from Auction site. If you see one that interest you see seek assistant from an expert, not a collector friend, or post it here on the forum we have lots of opinions here. - 2D photos are not always the best to see what is going on with a claw, I prefer handling one. Composited claws can be good and photos don't show you all the issues. - Good preservation and quality are key for making life easy in deciding if its a good claw or not. There is where it pays to focus on the better claws. Claws that are deformed, partial, compressed, beat up or have matrix on them are very difficult to insure you have a good one and especially hard for experts to positively say its good. It always best to save and wait to buy a higher end one. - As a general rule try avoid claws that have matrix glued on them or have seams with matrix. The matrix is there for only one reason to hid trouble. Matrix is a red flag, just tread carefully when looking at one of these. Ask yourself why risk it and buy a potentially problem claw, there are plenty out there that are clean. PRICE = Preservation (Quality) + Size - Repairs - Real claws are expensive, simple as that. Nice ones in the 6+ inch range can easily fetch over 1K depending on quality, 7+ inches can go over 10K . So if you see big claws under 1K there must be a reason unless its the deal of a century and they exist. Most of the claws I show are in the 1-2K range for 4-6 inches. Here are a few from the Tucson show to give you an understanding what real ones look like. Focus on shape, the articulation end, blood grooves and preservation. These two are clean no matrix, no compression may have been broken and reattached, reasonable preservation. Nice claws for any collection Higher Grade - Fatter, nice surface finish, good preservation, few if any repairs. Couple of more examples. Honest merchant shows, some repair and resto. Excellent high end claw around 7 inches very very expensive Fake Claws These two were laying in the box and the merchant said he just had them fabricated. They look pretty good to a novice both reasonable size and configuration. Probably copied from a good one. Red Flags : Check out the graining its does not follow the curve of the claw but is straight. Uniform Color and looks too clean. Finish is flat with no hit of sheen seen on bone. Super long ones are the most suspect, here are two in a box. Unusually long and thin, usually the dorsal curvature is not smooth to the tip has kinks, the preservation is odd, hard to see bone, lots of surface repairs. These may be composited, faked or combo? Who knows to risky to find out. Off an auction site - terrible fake easier to spot- 6.9 inch claw One of the hardest items to replicate is the blood groove that is on either side of the claw. The groove is the widest at the articulation end and slowly tapers to a point to form a channel at the tip that extends outward beyond the dorsal surface. Here is an example of a perfectly preserved one. Here is the tip of the claw from above and you can see the blood groove is just a channel in the claw. Another Characteristic on these claws is that when looked at from the top or bottom they are shaped like an isosceles triangle. Much bigger at the articulation end than the tip. Preservation may affect this but most should be tapered. Like most theropods, hand claws vary depending on digit so there will be variations depending on that and the number of different Spinosaurids that exist in Kem Kem. This is a big unknown and we believe these type of claws all belong to the Spinosaurid family. But here are a couple more you can check out the blood grooves, articulation and shape
  23. I am definitely an amateur when it comes to collecting and need some advice: I recently purchased my first 'larger' Spinosaurus tooth from a small gem/fossil shop in Seattle. The owner told me that it had no repairs or restorations, and that it of course came from Morocco. I tested the tooth under a UV flashlight and there were no anomalies, but I just wanted some more experienced opinions. The enamel looks good- no apparent cracks or suspicious color variations, root still has some of the matrix on it, but the tip seems a little suspicious to me... maybe I'm just being paranoid, but I have read so much about fake fossils and just want to be sure! Let me know what you guys think- Thanks!
  24. Why are Spinosaurus teeth so relatively common, compared to other dinosaur teeth?
  25. Hey Everyone, I know these get posted regularly but I'm hoping to get some advice on a Spinosaurus claw I purchased. Its a little beat up but a decent price and would be a first hand claw for me. Cons: The light color I know is usually associated with bone thats been carved, its 6 inches and not a bad price which Troodon will say are two large red flags. Pros: The tip fell off in shipping and I can say it is hollow inside, I THINK the grain of the bone follows the curve of the claw. I'm curious to hear what the forum thinks.
