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.

Hi again. I got this tooth and would like to get sure which species it is and which part of the mouth it could be from. Its in the matrix so sadly Im unable to see labial side. Tooth is curving towards so its lingual side if Im right. I marked tooth as A and believe it would be M. beaugei, but facets were bit difficult to see and get in a picture, but I would count 5 or 6. Its medium size and almost dagger shaped, so I think its not robust enough to be M.hoffmanni. I believe tooth marked as B would be M.beaugei with its more prismatic nature and having 5 labial facets. But I noticed that tooth I believe to be M.hoffmanni (3 labial facets) marked as C, has quite strong lingual facets too. Sorry Im not perfect with terminology, but it also has these half edges that I think does not create facet? Bigger M.hoffmanni one only has these half edges. So am I counting these right? Thank you for your answers.

Hello, This is a composite mosasaurus skull. As I can't afford the real deal, I normally look into this seminice pieces to try to find one that it's not a mess. I saw this one where the seller states that som teeth has been replaced (totally expected) and that has some repairs an reconstructions. At least for me comparing it to some other composite mosasaur skulls where all the bones are a mess, this seems more beautifully composited with a big part of the bones where they should be. Do you see some big red flags of it being a mess in reality with lots of more random bones than expected? What kind of mosasaur species it could be? Thanks!

Hi, so i just got this mosasaurus jaw from morocco, could someone help me to figure out if it is real? If so, is it possible to say from which exact species it is? Its said to be from morocco... Thank you in advance!

Hello, some years ago i bought this "mosasaurus tooth" at a fossil convention. Sadly I cant remember the details the buyer gave me exept that its supposed to be from a mosasaurus. Now that I have a few more fossils I am pretty sure that its fake... Could somebody please help me? Thank you!

Hey, I have a question... what do you think of the fossil i found at a store? Is it real? It's from ca. 80 Million years from marokko.

Hello everyone, I recently acquired a monstrously huge Mosasaurus beaugei skull which I would like to display in my house The skull measures 170 cm / 67" and weights 85 kg /187 lbs Does anyone have similar fossils which they mounted on their walls, or displayed in their cabinets? Thank you.

Is this a genuine Mosasaurus jaw fossil? If anyone knows, please let me know. Production area: Morocco Size: Long diameter of mother rock about 30 cm I appreciate everyone's comments! thank you very much!

Hi, I would like to buy this skull of mosasaurus, but I am not sure that it is a real fossil… could you help me please? thank you very much

Recently got back from a trip on Holden Beach, and just WOW. Words can't describe the uniqueness of being able to find Mosasaur teeth next to Megalodon teeth. The recent Hurricane brought in many new fossils and I had quite good luck. Here are some photos of the trip, I will post a picture showing all of my best finds shortly, but for now enjoy! First, here are some of the Squalicorax pristodontus teeth I collected. These were relatively common.

Hi everyone, I am trying to find the following stuff someone is willing to trade. - Mosasaurus partial jaws or matrix pieces, not repaired or restored. From Morocco. - Belgian Megalodon teeth - Mastodon tooth - Quality Spinosaurus teeth, larger ones. I got a lot to offer, mostly teeth and jaws from dinosaurs and ice age relater animals.

I was wondering if anyone would be interested in trading his/her mosasaurus jaw or partial from a site (Either United States or somewhere in Europe). I've got various amount of eurasian pleistoceen stuff, some dinosaurus teeth. Megalodon teeth of great quality too. Please if you know anyone, feel free to contact me!

Hello, what do you think, can i go "wrong" with these fossils from morocco? Are they real? Many greetings

Hi there members of this forum! Made the mistake(prety probably) and impulse bought this piece,which went by the name: "Mosasaur Dinosaur Jaw Teeth fossile" Im not shure it said from Morocco,but most stuff in the shop was there,so this one is probably i guess... Well now im kinda shure its "Jaw" section is made out of 3 pices,so im not shure if the rest is allso "legit". (I hope at least the theeth is real) So if any of you great fellows can help ID this.(Probably turns out to be some dessert folkart:) Sorry for the meh cellphone pictures ,and thanks in advance!

Good morning all, Been looking at purchasing a Mosasaurus jaw, but know to be weary of composites. What do you guys think of this one?? Is it authentic and or compostie?? I appreciate the help!!

Hello and thank you for checking this out. I picked up this 2.7" tooth that supposedly comes from Oued Zem, Morocco. I know next to nothing about Mosasaurus teeth, but I wanted to see if a species could be assigned to it. Serrations?: Thank you!

I had the opportunity and good fortune to participate in the excavation and preparation of a mosasaur this past year. The specimen was discovered by a new friend, Allison, in a small unnamed stream adjacent to family property in east-central Mississippi (? Prairie Bluff Fm, Upper Cretaceous, Late Maastrichtian).Allison found the first bones in early May and contacted me for help in identifying the bones through a mutual friend. I'm far from an expert, but was able to ID the bones (a radius and vertebra) as mosasaur. She was really excited, since the bones were her first vertebrate fossils other than a few Pleistocene horse teeth from the same creek, and promised to continue searching. On her next trip, Allison exposed part of a mosasaur jaw and sent pics to me while still in the creek. Long story - short version -- We (Allison, my grandson, Logan and I) began serious excavation in early June 2018 and continued collecting (several trips) and preparation through November. Dr. Lynn Harell, Paleontologist with the Alabama Geological Survey viewed photos of the specimen as I prepped them and helped to ID individual bones and confirmed the genus as Mosasaurus. Dr. Takehito Ikejiri, Alabama Museum of Natural History, worked with me to compare "Moose' (named by Allison) to many specimens in the archives of the Museum. Both were extremely helpful to me as we tried to confirm the ID and agreed that it should be labeled as Mosasaurus sp. until further study. George Phillips of the Mississippi Museum of Natural Science identified associated invertebrate specimens in hopes of confirming the geology of the site (still unconfirmed). 'Moose' was donated to the Dunn-Seiler Museum at Mississippi State University in December 2018. It will be studied as part of a graduate students research. Following are a large number of photos documenting the site, excavation, prepration, and bones of 'Moose'. Thanks for looking.

Hey guys, I just bought a relatively large Mosasaur tooth and I found what I believe to be another Mosasaur tooth mark near the base of the tooth, but I wasn't sure. Tell me what you think! Second picture I circled what I believe is the tooth damage.

Hi everyone! I purchased this "Mosasaurus Skull" about a year ago. I'm certain that it's fake, but I was curious as to how bad of a fake it was (to humor me) and what kind of teeth these are. Thanks!

@pachy-pleuro-whatnot-odon and I wrote a paper on Mosasaurus hoffmannii fossils from the Moroccan Phosphates. https://www.researchgate.net/publication/357836567_Occurrence_of_Mosasaurus_hoffmannii_Mantell_1829_Squamata_Mosasauridae_in_the_Maastrichtian_Phosphates_of_Morocco https://www.aaps-journal.org/pdf/JPS.C.22.0001.pdf Abstract: Marginal tooth crowns from the hypercarnivorous marine reptile Mosasaurus hoffmannii Mantell, 1829 are reported for the first time from the Late Cretaceous (Maastrichtian) phosphates of Morocco. Fossilized remains of this species are previously known from Campanian and Maastrichtian outcrops in Europe, North America, and western Asia at a paleolatitudinal belt of 30-45°N. New fossil material originates from the Upper Couche III layer of the Oulad Abdoun Basin, south of Oued Zem, Morocco. The discovery of M. hoffmannii in Morocco extends its paleobiogeographic range south to 25°N and into the southern margin of the Mediterranean Tethys.

This Mosasaurus tooth measures 8.3 inches from Morocco. Can you tell me what species it is?

I was told this is a Curry (or currii) mosasaurus, but now I am having problems identifying it. What are your thoughts? I think it's a beautiful specimen, but I just wish I knew more about it. Any help?

A couple of weeks ago, I acquired a gorgeous fish and mosasaur association, from a seller on the web. It hails from the Cretaceous of Khouribga, Morocco, unprepped, just split out of the rock! Here's the fossil in question! Ignore the mess in the background... Can you believe this thing is 70.6 - 66 million years old!? Look at the sheer awesome preservation on that fish spine; absolutely stunning! So, story time. The tooth is from the species "Mosasaurus beaugei", a pretty large mosasaurine. Here's a nice image (or, 2 images...) of the size of Mosasaurus (silhouette 16) against other mosasaurines, and a human. As you can see, that's... A pretty big beasty! It came from the Ouled Abdoun Basin in Morocco, which is a HUGE sedimentary phosphate basin - so big that it holds nearly half of Morocco's phosphate reserves, which is over 26.8 billion tons of phosphate (24,312,551,032,000 kilograms). That's... A lot! To be precise, but in an interesting metric, that's 50 humans worth of phosphate for each human on the planet, or 3,078 kilograms for each of us! Anyways, geology cool and whatever, but we're here for the fossils. The O. A. Basin is absolutely fascinating. Its deposits range in age from the late Cretaceous (100 million years), to the late Eocene epoch (48 million years). That alone is fascinating, but it's the sheer amount (and quality) of vertebrate fossils to be found here that makes it so special. Shown above is a typical phosphate quarry in Morocco. In 2017, a whopping $6.12 billion USD worth of minerals and precious metals were mined, making it one of the most important industries in the whole country. Large phosphate deposits such as this form in seawater, particularly areas rich with animal corpses and nutrients. This, obviously, means that phosphate beds are usually choc-full of fossils. As the phosphatic rock is so greatly mined, tonnes of fossils come out as a by-product. Locals collect these unfortunately fragmented fossils (hence why few whole specimen come out), and sell them. Too many fossils are fabricated, using a real tooth or bone and setting it into a fake jaw or matrix made out of dust, plaster and glue, such as these: There are many a post on this forum explaining how to spot these composites. The images above show the most common fake fossils from Morocco. The teeth (Otodus obliquus and Mosasaurus sp.) are real, but have been collected and set into the fake jaws and rock, to make them look more attractive and sell for more money. This by itself would be okay, however these fossils aren't sold as "composite" (called composite as some of the fossil is real), they are sold as real, 100% natural fossils, making it fraudulent, and illegal. Still tourists buy these, unknowing that they are composite. A really good article on Moroccan fossils can be found here: www.fossilguy.com | Why are there so many Otodus fossil shark teeth and Mosasaur teeth from Morocco? Not to mention, the fossil trade in Morocco is quite lucrative, but also sometimes highly unethical. I always make sure to purchase from ethical sources, and the fossil shown in my photos is no exception to this rule. Anyways, enough about the facts, lets prep on! I began by (very, very carefully) soaking the specimen in a controlled room with 5% vol. acetic acid, which should weaken the matrix, allowing me to reveal details previously hidden. Then, delicately, I used a needle and pin vice to lift up the matrix, exposing the fossils. In the photo, you can see I packed the tooth in with tissue, to ensure it doesn't come off, as I wish for it to remain in-situ. I then started to reveal a fish rib that was almost entirely hidden! You can see it poking out to the left of the tooth. Finally, I started to expose the fish vertebra (spine plate) above the rib, which came out somewhat stickily, but is now very pretty, if not a little distorted under the weight of the rock. And here's the final piece (for now)... There's more to prep out, for example a heavy load of bone mass towards the top of the piece, and a suspect coprolite in front of the spine, but that is another times' task - I've already spent dozens of hours soaking, needling and drying out this specimen!
