  1. Mosasaur Jaw

    Hello everyone! I just acquired this piece but the only thing I know is that it's a mosasaur from morocco and it shows the lower jaw and the pterigoid teeth from the upper jaw. Can any mosasaur experts here help me identify the species? I'm thinking of prognathodon maybe?. Also as far as I know it's not fake or composite but would be great if you could confirm it. Thank you very much for your help, very appreciated! Greetings from Spain.
  2. Hello, i am a Student from Germany. I have recieved the Task of analyzing the huge fossil Collection of my School, which includes this tooth. According to a profile (that appears to have been made by a fifth or sixt-grader), it is from Oued-Zem / Khouribgha, morocco. My best guess is that it is from Prognathodon. It is about 2,5 to 3 cm Long and 1 cm thick. Many thanks in Advance!!!
  3. Prognathodon posterior teeth

    Hi again I have a question what did prognathodon use it’s posterior teeth for I was just looking at a skull and they seemed different do they have a different use then the other teeth? @Troodon
  4. Yesterday I made a visit to the Natural History Museum of Maastricht (The Netherlands) for my Birthday The museum is only a 40 minute drive from where I live and it showcases the entire natural history of the region, the cool thing about this museum is that the fossils which are showcased here are all regional fossils from The Netherlands, Germany & Belgium. I am starting the topic off with 2 pictures of the special exhibit called Microsculptures, which shows giant detailed photographs of insects to show how magnifecent they are. Then I went on to the "Mosaleum" which holds "Bér" the holotype specimen of Prognathodon saturator
  5. Large Prognathodon Jaws

    Posting this a few days after driving four hours down to Tennessee and picking this bad boy up! It’s definitely the center piece of my collection thus far. Also want to say a quick thank you to all those who helped ensure the authenticity of this piece! Wasn’t about to pay all that money without being 110% sure! I did manage to come at the right time though, the shop offered a 20% post Christmas discount which helped a lot also, any opinions on the "bite mark"? I'd be more than happy to upload more photos if needed!
  6. Histology and osteology/Cretaceous

    LINDGR Lindgren, J., Uvdal, P., Engdahl, A., Lee, A. H., Alwmark, C., Bergquist, K-E., ... Jacobs, L. L. (2011). Microspectroscopic evidence of cretaceous bone proteins. PLoS ONE, 6(4), [e19445]. DOI: 10.1371/journal.pone.0019445
  7. Hey guys. Newb here. I picked up this mosasaur tooth at a local shop today, I’ve read through the forums about some fake settings with the jaws and whatnot but was wondering if just from the pics if anyone can tell me whether this setting with the root looks real, or did i just buy some teeth set in a fake mold.
  8. Hi everyone, With this thread I wanted to start a discussion about what the feeding habits would be for most mosasaur species, how you think they would have fed. I personally love mosasaurs, they are one of my favorite prehistoric animals for a number of reasons and I’ve recently even bought my first Prognathodon jaw and I also live in an area that is not only known for their fossils but also for the discovery of mosasaurs. I’ve been doing a bit of reading lately about mosasaurs but I can’t really find anything difinitive on their feeding habits. Their diet yes. But exactly how they consumed their prey, not yet. I personally work with reptiles on a daily base, both with my job and with my hobby and I know quite a bit of different feeding behaviours with these animals. And as I was feeding the ball pythons (Python regius) at work I was kinda wondering, how would a large marine reptile like a mosasaurus eat? Would they just tear off chunks of meat like their closest living relatives the monitor lizards? Or would they perform deathroll like crocodiles do to tear of chunks of meat of their prey? Or when we talk about smaller prey, would they just swallow them whole like a snake does with it’s two lower jaws that can move independently, would a mosasaur be capable of that? Or would it be a mix of all those things or something entirely different? So I was just wondering what are your thoughts on the subject? I love to hear your theories and own finds and observations or if anyone ever read something in a scientific paper about the matter. I am dying to know your thoughts on the matter, as I want to learn as much as I can about these magnificent beasts!
  9. Mosasaur prep, jaw section

    PART 1, acquisition This piece was acquired via the "for sale" section of the Forum. The seller, @Fitch1979, Dries offered several jaw specimens, which were clearly superior to the mostly spurious Internet auction site examples. Dries provided some provenance on the fossil. It had resided in his family's private collection for over 26 years. It had been purchased at a gem and mineral show in Ghent from a collector who acquired the specimen in 1978. After a pleasant exchange with Dries, a bargain was struck and the specimen shipped on December 9, 2017. Since the piece was located in Belgium, arrival involved a seemingly interminable wait. Finally, the tracking indicated arrival at US Customs on December 29th. Then the real wait ensued. The tracking was not updated until January 22, 2018. At that time notice was given that the package had been turned over to the "postal operator." Curiously, it arrived on my SC doorstep that very day! It was a surprise to open the door and find the huge (shipping weight 28 lbs.) shipping box resting there. Here is the image posted to the Forum offering the fossil for sale. ...to be continued
  10. Mosasaur tooth

    I got this tooth as a freebie when I bought some fossils a while ago. I know it's a mosasaur tooth of some description and my guess would be Prognathodon sp. based on how common they are, but I'd like confirmation (if possible) for my own peace of mind. I know it's not easy ID'ing based on tooth crowns, but hope springs eternal. The tooth is about 3.5 cm long.
  11. Prognathodon Tooth from Morocco

    From the album My Fossils

    I found this tooth from Morocco I’m a shop in Portugal. While the root could be faked in someway. The actual tooth, is real. I did a post on this before but I took much clearer images for the ID for this later on. I decided to repost with these images.
  12. Prognathodon (Mosasaur) tooth from Morocco

    I found this fossil in Portugal in a little shop. The tooth was from Morocco and is likely a Prognathodon. While the root has been said by others to be likely fake, the crown (the main point of the fossil) is likely real.
  13. I got this jaw in the post today. It's 26 inches long, and seems to be the upper left jaw of a large-ish mosasaur, perhaps Prognathodon? The teeth don't provide much of a clue, since the crowns are, sorry to say, all added in afterwards. I knew this when I bought it, and I paid what I consider to be a fair price for a jaw of this size with botched-up teeth. My aim is ultimately to extract it, and mount it. At that point, I can sort the teeth out to a better standard, and replace the worst examples. I'm interested in any thoughts about the jaw in general - whether you see any obvious signs of tampering or anything unusual. I really wish people wouldn't interfere with these fossils to begin with! Thanks.
  14. Mosasaur: Prognathodon?

    Hi all, Usually you see these fossils in the "Is it real?" thread, but I decided to make a change. This mosasaur block contains several teeth, and I think they are real, and it is possible that the block was found as such (if you think any of it is fake/reconstructed, let me know). As usual, it's from our favorite mosasaur location Khouribga (Morocco), meaning it's from the late Cretaceous (like all mosasaurs). Now I would like to put a species (or several species) on these teeth. Here's a list I found of the different mosasaurs found in Khouribga (it may be wrong): Globidens phosphaticus (definitely not this one) Halisaurus arambourgi Halisaurus walkeri Mosasaurus hoffmani Platecarpus ptychodon Prognathodon curii Liodon anceps (?) All of them (except for Globidens) seem like possible solutions for my block. So, what species do you think it is? Maybe there are different species for the different teeth? Thanks! Max
  15. Prognathodon anceps

    What is the "anceps" in Prognathodon anceps? Is that the species name? I'm having a hard time finding anything online to explain other than some dealers selling some teeth on various sites. Sorry for my ignorance and thanks!
  16. Prognathodon tooth

    Tooth of a durgophagous mosasaur.
  17. prognathodon tooth

    i am certain this is a prognathodon tooth a tooth of my favorite mosasaur the fossils are real but the block its self is fordged henc a otodus tooth begin in the block
  18. I like Mosasaurs so I've been buying some cool stuff here and there for a while now. I have some loose teeth with and without roots and a few jaws. for a while now I've been noticing some interesting patterns. Or rather a single pattern that keeps showing up. I have 42 loose teeth and a number of these teeth have some wear patterns on them. Some just have some random wear here and there or tips broken or worn off of them. But a significant number of teeth have damage to the enamel on the front side of the tooth. Sometimes on the lateral side and sometimes on the labial side. Sometimes on both sides. Of these 42 teeth, 13 have significant damage to the enamel on the front. In about 8 or so the pattern is quite similar. This pattern seems almost exclusive to the large Prognathodon teeth with the only exception being a Mosasaurus beaugei? tooth that has some wear on the front. Though this tooth isn't nearly as damage on the front as the big Prognathodon teeth. This same wear pattern also shows up on a Prognathodon jaw that I'm still prepping. This jaw shows the same damage while the teeth are still mostly in the original position aside from some minor drifting. This pattern also does not show in the jaws of other mosasaur species I have. So I'm wondering is if this could possibly be as a result of some behaviour that Prognathodon might have had. Since quite a lot of the teeth show the same type of damage and it also shows in still rooted teeth. Have any of you ever seen this same pattern on mosasaur teeth? I'm wondering what your opinions are on this. My loose mosasaur teeth, one not shown. Big Prognathodon teeth at the top. Some possible Eremiasaurus teeth below them. The small recurved tooth crown on the left is Halisaurus arambourgi. Below it two small Platecarpus ptychodon teeth. Under those two badly crushed teeth. Lower left middle Mosasaurus teeth, some probably M. beaugei and some M. hoffmanni. Globidens teeth at the bottom. Prognathodon, Mosasaurus and Globidens rooted teeth on the left. Teeth with damage on the front. Only three that aren't Prognathodon at the bottom. Detail of a Prognathodon tooth. Prognathodon jaw with the same type of enamel damage on three teeth. The teeth towards the front are too damage during the fossilisation to tell if they have similar damage.
  19. I was hoping some of our Mosasaur experts (@LordTrilobite @jnoun11) could lend me their opinion on the following Mosasaur from Morocco I want to purchase. I was told it is Prognathodon, agree?

  21. Maastricht Natural History Museum Mosasaur central This charming little museum in a historic city is absolutely worth a visit if you have any interest in the latest Cretaceous and Mosasaurs. The city of Maastricht was founded by the ancient Romans along the Meuse (Mosa in Latin, Maas in Dutch) river. The animals we know as Mosasaurs are named after this river. The great lizard of the Meuse. Near the city are deposits of the latest Cretaceous, the Maastrichtian, which is named after the city. There are several quarries that produce a lot of fossils. In the same procince to the north of Maastricht there is another fossil location that lends it's name to a geologic age. The tiglien, which is during the lower Pleistocene, named after Tegelen. Part of the old roman city wall nearby. This museum also used to house the holotype of the original Mosasaur. Mosasaurus hoffmanni. Sadly it was taken as the spoils of war by Napoleon's army. Today the holotype is located in the Paris Museum of Natural History. So now there is only a cast of the holotype in the museum. This small glass enclosed area in the garden houses the holotype of Prognathodon saturator which is nicknamed Bér. The specimen consists of an mostly complete skull and a partial skeleton and was found near Maastricht. There are a number of articulated thoracic vertebrae, some limb elements and some other loose elements. Along with the mosasaur skeleton there were a lot of shark teeth (Squalicorax and others) found associated with it that suggests that the carcass was scavenged by sharks and other opportunists before being covered. I suggest viewing this on a cloudy day because the reflections on the glass can sometimes make it hard to see as well. Though the main attractions are the Cretaceous and Pleistocene fossils. There are also a few other cool things. An early relative of the Horseshoe Crab. A primitive spider.
