  1. Help with some teeth

    Hello, Before I made this post I did some research by myself. By scrolling through the forum here I already learned that the teeth I have in my collection are composites. I also have doubts with the Spinosaurid tooth. It is not serrated but it has a sharp edge in both sides. I thought they had to conical with striations? The Mosasaurs hoffmanni and the Elasmosaur sp. are valid I think (even if they are composites). I even believe the Elasmosaur is a broken tooth put back together and not built out of different Elasmosaur teeth. I am curious for your opinion. First three photos are from Elasmosaur sp. number four and five are Mosasaur hoffmanni six to eight is Spinosaurus aegypticus according to label, but I prefer to label it as Spinosaurus indet. cause I'm not sure. I thought I read somewhere on the forum that Spinosaurus aegypticus would only be valid in Egypt. All three teeth come from Morrocco. The Spino and Mosa were super cheaps (I think that should be a hint). I paid 10€ per tooth. The Elasmosaur was 27€.
  2. Hi all, I was recently offered this tooth from late Cretaceous of Orensburg, Russia. Most likely Gaisky City District. I can't figure out if it's a Polycotylid plesiosaur or Pterosaur tooth. The overall shape is closer to pterosaur than plesiosaur. However, I am not aware of pterosaur having wrinkling like that, nor do I know of pterosaur teeth being found there. What are your thoughts on this? Thank you.
  3. I can’t figure out if these are 2 associated jaw pieces. In most pictures they sure look it, but some pictures make me second guess it, and if they aren’t, they’re definitely still the attaching pieces, even if from different animals. I was looking at it backwards for awhile, which set me back, but I figured out the thicker part is actually the front of the jaw, right before the curve, or right after it starts, if it’s been glued on at the incorrect angle, which I think could also be possible. the 1st picture looks very strange because of how that smaller section suddenly drops down and gets taller, and especially strange after researching and finding out that it’s supposed to get wider there, but actually SHORTER. the 2nd picture looks good, except it MIGHT supposed to start slightly curving inward at the point of reattachment pics 1,3,4,6,&7 all make it look like they rent supposed to be associated together, but the other pics make it look very accurate. I don’t know what to think, so I thought I’d see what people with much better knowledge than I, think about it.

  5. Largest Elasmosaur Ever Found

    Antarctic fossil Elasmosaur largest ever found https://www.nationalgeographic.com/science/2019/06/fossil-sea-monster-found-antarctica-heaviest-of-its-kind-elasmosaurs/
  6. From a plesiosaur?

    From all the comparing Ive done, i think it almost looks exactly right, except I haven't been able to find any vertebrae with the things on the bottom(chevrons?) shaped like that; that 90degree bend. Is that familiar to anyone? Is that something that appears on plesiosaurs or not? (no better angle of the chevron(?)on the other side)
  7. Elasmosaur jaw?

    Could this be a plesiosaur(elasmosaurus) jaw? I tried comparing but it's hard to see the picture of jaws in ideal positions and angles and such. Also, with so many extreme teeth it can be hard to see perfectly in a lot of pictures. (Location-wise and all, it could be, this is just about the physical jaw itself)
  8. The plesiosaur has long been one of my favorite prehistoric creatures of all, especially after reading tales of the Loch Ness Monster. I've always wanted a jaw from one, thankfully @StevenJDennis recently scouted this beauty for me from Tucson. I estimate roughly 30% restoration, mainly to the rear portion of the joint(?) and some filler. Also, majority of the teeth have been planted from Zarafasaura oceanis, another elasmosaur. Still, he's earned a spot as one of my showpiece fossils. He measures 17 inches long and 7 inches wide. Plesiosaur Mandible Elasmosauridae (Libonectes atlasense Buchy, 2005) 94.3 - 89.3 million years old | Turonian, late Cretaceous Akrabou Formation Asfla Village, Goulmima, Errachidia Province, Morocco I assume this is an erupting tooth
  9. Here is a sequence of pictures of a Zarafasaura jaw that I just finished preparing and restoring. It started out as not much to look at but turned out pretty well in the end. I did not restore the rear of the mandibles, only what needed to be done to make it a great looking piece. You can follow along through the pictures. Enjoy. Seth
  10. I came across this absolutely bizarre looking skull on our favourite auction site. Most of the bones look pretty real. It looks nothing like the known Elasmosaur from Khouribda. Zarafasaura has a really short nose and gigantic jaw muscles. Besides the teeth this looks nothing like it. Most of the bone seems to be real and while there definitely seems to be some repair/construction. Most of the real bones seem to fit together. Some of the teeth are definitely plastered in. Though there seem to be some unerupted teeth that do actually belong to the jaws. The top of the snout also looks completely bizarre. What I think has happened here... Is that someone took a crocodile, mosasaur and elasmosaur and mashed them together. Look at the back of the skull. This looks like the back of a crocodile skull to me. I'm not sure where the jaws come from (maybe croc?) but the teeth are definitely those of a plesiosaur, probably Zarafasaura. The top of the snout had me confused for a few minutes but I think that this is actually the frontal and parietal of a mosasaur. Notice what looks like the parietal eye filled in with a chunk of bone in the middle top off the skull. So yeah I think this is an absolute abomination. Steer clear folks...
