    Mosasaurus stelladens tooth ?

    Hello, i am interested im buying this mosasaur tooth. It has an interesting enamel structure which i only know from Mosasaurus stelladens. Sadly this are the only pictures of it. Is it maybe one ? Or just a positional tooth ?
  2. Some of the nicer fossils from Morocco that I own. Let's start! - Set of nice spinosaurus teeth. Found in the same tunnel and layer. Only some meters away from eachother. 11 and 10.8 centimeter KemKem group, Morocco - Hainosaurus Boubker jaw pieces (dentary + snout) associated from an adult specimen. Really rare. Sidi Chennane, Oued Zem Morocco - Huge 10.6 centimeter carcharodontosaur crown with neat orane/brown like colors. KemKem group, Morocco - Set of 35 associated Otodus Obliquus teeth. Biggest one measures 8CM. Took a while to find one. El Khourigba, Morocco
  3. Hello everyone! I'm here seeking for help with the ID of this Mosasaurus rooted tooth. It comes from Ouled Abdoun, Morocco. The seller said that it's a pterygoid tooth. If you think it is correct, what are the distinctive features to recognize species and that it is a pterygoid tooth? Thank you so much!
  4. Found in an area overlooking the Little Missouri River basin, Clark County , Arkansas. I have found mosasaurus vertebrae, ball and socket in the general area where I found this one. My confusion is the intervertebral socket. Also, the overall shape is not round but flatter and with a figure 8 shape. Please comment and if possible, what is it.
  5. Hello, I have these three replicas of a Alamosaurus, a Mosasaurus, and a T-Rex tooth in my collection, and they seem to be very old. Has someone an Idea how old they are and how rare they have become? Thanks !
  6. Hey guys! While on vacation my brother nephew and I wondered into a fossil shop and I helped them pick out a nice tooth and jaw from a mosasaur which I identified as Mosasaurus beaugei. My question is, is it a composite or a partial jaw with tooth? I'm leaning towards composite, but I wanted a second opinion. Don't worry about my nephew, he's aware it might be a composite and is THRILLED with it either way and it wasn't expensive. Quarter is for scale. Thanks!

    Moroccan mosasaur

    Hello, could someone please help me find out which species of Moroccan mosasaur this jaw fragment belongs to? 2x2 inches
  10. 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!

    Mosasaur vert.

    Howdy all, Interested in this nice mosasaur vertebra found in the North Sulphur River, in the Ozan Formation. I'm curious of what species of mosasaur are present in this formation and if there's a way I could ID this vert to one of those species.
  12. Hi everyone, From now on I will post my hunting trip reports to Eben Emael as I often forget to make separate posts for them. I visit the Romontbos Quarry in Eben Emael multiple times a year with our fossil club, the BVP (Belgische vereniging voor Paleontologie). It's one of the last active locations that's still accessible in the Maastrichtian Type Location that allows hunting, and the quarry is only a 20 minute drive away for me, so that's ideal. DISCLAIMER: For all new fossil hunters: This location is off-limits for individual people! You cannot go hunt there on your own. The quarry is very strict and does not allow trespassing. This is an amazing location with great fossil finds, so I cannot stress it enough to not enter this place illegal as it could put a stop to fossil hunting for everyone here. If you want to go on a fossil hunt here, join the BVP! They are the only ones with permission to access the quarry, and they organize multiple excursions to the quarry each year under strict safety protocols. If we behave, and no one blows it by trespassing, we should be able to have access to this quarry until the year 2043. Now that's out of the way, let me introduce this amazing location which is my favorite place to hunt! The Romontbos quarry in Eben Emael is part of "Mount Saint Peter" which lies on the Dutch/Belgian border and is home to the so called Limburg/Liege chalk also know locally as "Limburgse mergel" which was often used as building blocks in the past which is why you can see serpulids, oysters and urchins in the stones of old buildings in the region. The quarry is located only a couple of km from the city of Maastricht and "Mount Saint Peter" is the location where one of the first biggest fossil discoveries has been made, a skull of Mosasaurus hoffmanni A.K.A "The Beast of Maastricht" back in around 1766. The layers of Eben-Emael are part of the Maastrichtian type locality dating back to around 70 - 66 million years ago, during that time this area of Belgium and the Netherlands was part of a shallow tropical sea. The layers in the quarry have a very rich fauna and floral list: You can find many bivalves (Acutostrean Agerostrea, Pinna, Neithea, ...), Gastropods, Brachiopods, Serpulids, Belemnites, Crustacean claws (Mesostylus faujasi), sea urchins (Hemipneustes striatoradiatus, ...) and shark teeth (Squalicorax, Pseudocorax, Palaeohypotodus, ...). For the microfossil lovers there is also oportunities to collect Bryozoans and Forarminifera There is also fish material like fish teeth and the odd scale or vertebra to be found, or if you are very lucky you can find fossils of one of the many species of Mosasaur and Sea Turtles that swam in this shallow sea. But also plant material can be found like Sea Grass (Thalassocharis) of which this quarry is one of the only places in the world where you can find sea grass. But also Conifer material has been found regulary at past excursions. Also known from this location and other localities in the Maastrichtian type locality but exceedingly rare are ammonites, crab carapaces, sawfish material, Elasmosaur material, dinosaur material (Betasuchus and Hadrosaurs), marine crocodile material and bird fossils. It is in this same quarry that "the wonder chicken" Asteriornis maastrichtensis and Janavis finalidens were found. Should you see me on one of the excursions, feel free to say hi and come for a talk! Also feel free to share your own fossils from your trips to Eben-Emael, the more the merrier!
  13. To pass some time I've been recently researching early Paleocene life and I keep coming back to researching (in my view) the two strangest and controversial Late Cretaceous-Early Paleocene Formations I know of. These are the Hornerstown Formation dating 66.5-65.5 Million Years ago in what is now New Jersey, U.S. And the Takatika Grit Formation dating 66.5-60.0 Million Years ago in what is now the Chatham Islands, New Zealand. https://citeseerx.ist.psu.edu/document?repid=rep1&type=pdf&doi=0b3baee9ab1afc7973337f5047495b723fcfa4f2 https://www.researchgate.net/publication/315461615_The_age_of_the_Takatika_Grit_Chatham_Islands_New_Zealand https://www.sciencedirect.com/science/article/abs/pii/S0195667109000184?via%3Dihub I've read many reports about these formations and the pretty controversial stuff that's been found in both these areas (Paleocene ammonites and reports of archaic marine reptiles like Paleocene Mosasaurs). I'm really not 100% sure what to make of this as I've heard conflicting hypotheses on whether these more archaic marine reptile fossils were reworked from older formations while others say it's not too too likely? https://www.cambridge.org/core/journals/journal-of-paleontology/article/abs/maastrichtian-ammonites-from-the-hornerstown-formation-in-new-jersey/4F051D07668B7B893EEFECF0506E2F1B https://bioone.org/journals/acta-palaeontologica-polonica/volume-57/issue-4/app.2011.0068/Short-Term-Survival-of-Ammonites-in-New-Jersey-After-the/10.4202/app.2011.0068.full For most of these "controversial" specimens, I would say reworking is likely while some I'll admit I'm not sure? For the Mosasaurs, it's clear that the astroid impact 66 Million Years ago caused their total extinction, but I'm still not 100% convinced that none emerged from the event alive (at least barely) and swam the seas in the very first days of the Danian Paleocene but not too long after. Unlike the mostly terrestrial Non-Avian Dinosaurs, which could only hide in so many places and it's very unlike more than a tiny amount of individuals (not enough to support a population) made it into the Paleocene, the Oceans have slightly more areas to hide and more even for endothermic air breathing animals like Mosasaurs (though as an endotherm, food does become a major issue especially when the ocean food chain nearly collapsed completely). What I'm wondering is how valid are at least "some" of these supposed archaic marine reptile and ammonite fossils from the earliest Paleocene sections of the Hornerstown Formation and the Takatika Grit? Also, of all the Maastrichtian Mosasaurs known so far, which ones would have been the mostly likely to have (at least briefly) survived the Cretaceous-Paleocene Extinction Event of 66 Million Years ago (would it have been generalist feeders, ones that specialized in deep sea hunting, ones with cosmopolitan distributions, ones small by mosasaur standards but still around the same size of the few confirmed large reptiles that survived the event like the 8 meter (26 feet) in length Thoracosaurus, or ones with all these traits and advantages)?
  14. Hey there, It‘s my first post in this Forum, so it‘s time to say hello. My name is Philipp, born in Germany/Saxony. I grew up in the Erzgebirge and was surrounded and fascinated by mines and minerals when i grew up. On my current travel through Europe and Morocco the passion for Minerals and Fossils flamed up again. It’s hard for me not to think every moment about where I‘m going fossil/mineral hunting again so i don‘t annoy my girlfriend tooooo much ;) I’m currently in Morocco for a 3 Month trip to search for fossils and minerals. I was reading about the Mosasaur teeth in the Oil Shale Deposits near Bakrit/Timahdite and about some members visiting this area. I was wondering if someone can give me some locations where these teeth can be found. Looking forward to your answers Philipp
  15. I live in morocco and everytime i got to Marrakech,i would go buy fossils from shops and i always recognize 50 percent of the time if it's fake or real but that is the problem,i can never know if it's real or false with teeth and i was just wandering if anyone knows a way to identify a fossil while buying it and not seem suspicious to the seller. And also this is a tooth i bought last week of the mosasaurus family.the mesurement is in cm.

    mosasaurus jaw

    Do you know what kind of Mosasaurus this is? Produced from Morocco. There seems to be no detailed information.

    Mosasaurus hoffmanni tooth?

    Hello, I have another mosasaur tooth ID question. This is listed as Mosasaurus beaugei from Kem Kem Morocco, on the small side at just over 4.1 cm. Based on what I recall @Praefectus said, is it possible this is actually a M. hoffmanni? It has very few, prominent facets, which are apparently diagnostic to hoffmanni rather than beaugei? @pachy-pleuro-whatnot-odon Sadly the tooth doesn't seem in the best shape though. Thanks!
  18. The unnamed giant Tylosaur of the Moroccan Phosphates is revealed at last. The great and mighty Hainosaurus is a previously unrecognized macropredator present in the latest Cretaceous (Maastrichtian) of Morocco. https://www.researchgate.net/publication/365437927_First_Record_of_a_Tylosaurine_Mosasaur_from_the_Latest_Cretaceous_Phosphates_of_Morocco Authors: @Praefectus @BrennanThePaleoDude @pachy-pleuro-whatnot-odon Abstract: The latest Cretaceous Phosphates of Morocco preserve the highest biodiversity of mosasaurid squamates anywhere in the world. Intensive sampling over the past century has uncovered at least ten genera and thirteen species from the mosasaur subgroups Halisauromorpha, Plioplatecarpinae, and Mosasaurinae. Notably missing from the assemblage are members of the macropredatory Tylosaurinae. The Tylosaurinae were globally rare in the Maastrichtian and their apparent absence has been previously explained by either collecting bias, ecological preference for deeper waters, or habitat restriction to higher paleolatitudes. Here, we describe a new tylosaurine mosasaurid, Hainosaurus boubker sp. nov., based on several partial skulls and isolated teeth originating from the Couche III layer of the Sidi Chennane Phosphate quarry near Oued Zem, Morocco. It is unique amongst tylosaurine mosasaurids in possessing blade-like teeth that are laterally compressed, encircled by enamel facets, and differentiated along the dental margin. The discovery of this new taxon in the Maastrichtian of Morocco is remarkable as it represents both the youngest species of Tylosaurinae and the first occurrence in North Africa. It has been a pleasure to work on this project and I am so happy to finally see it come to a conclusion. Tremendous thank you to Boubker Chaibi (Instagram @foussilouedzem) for discovering and donating the type material. Additionally, thanks to Carlos Espinosa (Instagram @carlost_sapiens) for bringing Hainosaurus to life. Funding for this project was provided by the Association of Applied Paleontological Sciences’ Charles H. Sternberg Scholarship for vertebrate fossil research. Thank you very much the members of the AAPS.

  19. After I rejected the seller’s offer. He sent me another one. And he named it is an original piece. So I upload the photos here. And I hope to ask the opinions again. Hope it won’t bother you all too much. Thank you.
  20. Hello everyone! I'm here seeking for help with the ID of this Mosasaurus jaw section I recently bought. It comes from Ouled Abdoun, Morocco. I don't know much more, and I'm just becoming crazy reading that there are more than 18 Mosasaurus species from Morocco The seller didn't commented on the ID, but he said it may be an Eremiasaurus. What do you think? Also, do you think that the bone on the bottom left is the left side of the jaw? Thanks in advance!
  21. Hi again. May I have the opinions of this jaw also? Thank you so much.
  22. A Morocco seller sent me a head of Mosasaurus. But I have no idea of it. May I have some opinion from the experts of forum, please? Thank you.

    Out of place mosasaurus vertebra?

    I was out on one of our Miocene beaches famous for the fossil crabs and found a vertebra which looked quite different to other dolphin / whale vertebra I've found but I still put in down as some type of cetacean vert. Some eagle eyed fossil hunters and paleontologists identified it as a potential mosasaurus vertebra when I posted it online (thank Carl!) There are some cretaceous deposits further inland, so potentially it could have been transported by a river or similar down to the beach. It has a definite concave and convex face to it. Is there any other animal it could be, maybe from the cenozoic?
  24. Fullux

    Mosasaurids

    Anyway to identify some isolated mosasaur teeth? I got these from one of those little fossil kits when I was a kid. I'm assuming they're from Morocco.
