Hey all! I’ve got a piece I’ve been looking at and considering purchasing when I have the funds. It’s marked as a Mosasaur rear jaw section, and it’s not reading to me as such, but I still have an interest in bones from the area so I figured it was worth a shot having the experts look at it. I’m hoping to improve my fossil preparation skills and I’m interested in doing some restorative work on some less special pieces.

An afternoon reporting... fake Mosasaur jaws.
charlie3425 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Here is a way to spend a gloomy winterish afternoon. Searching, (easily) finding and reporting fake fossil fabrications. This time the 'Shop for handmade, vintage, custom, and unique ... ' got some signals. These sellers are a real disgrace. Hope I saved some beginning fossil collectors from a bad start...

@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.

Prognatodon currii 'slightly' restored
charlie3425 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I just had another bad experience with the famous auction site wich I can not mention by name as I understand it. (Even my cat could find it in an encyclopedia though...) This time I placed a quick bidding on a - as it was advertised - slightly restored big fully rooted tooth of a Prognatodon currii. To my exitement I won the bidding. Taking a better look at the photo's of the item my doubts grew and on its arrival yesterdag my worries were allas confirmed. The tooth was firmly and totally cemented to the root with a mixture of sand and glue (in a colour nearly matching the fossil). Other breaklines in the root were cemented in the same way (this bothered me less). How about that for a 'slight' restoration. It is possible that the root and crown are just parts of two different fossils. Impossible to know. So I have this argument with the seller who claims the description mentions it is restorated and I should not expect any better for this price... So be warned. Ask for more information before bidding and zoom in on the pics if possible. I will quit my account for that website now. Looking back I can say half of the items I won/bought on it caused me some form of dissapointment. I'll buy from experts only, I never had any problems with scientists and experienced people. Should I give the seller a negative or neutral review? Or was I just too ignorant? Happy to shake it off a bit over here. It's not about the money, it's the new crack in my trust that hurts a little.

Hi! As I have read about Moroccan Mosasaurs. And know if there is any new species or updated names? Halisaurus walkeri. I have read that this is a temporary name for this new? Rare? Mosasaur. Read also that the teeth are all the same size, probably young adult, and Mosasaur migrants. Not sure if this is real. Prognathodon giganteus I have a Mosasaur tooth labeled as a p. giganteus. But I have not seen sellers use this name. Is it outdated? Liodon anceps This one I also have labeld as liodon anceps. But I have seen teeth being labeld as Prognathodon anceps. Same species? These are the ones that I'm not sure about the species name. But I know there are tons more of Moroccan Mosasaurs. If anyone knows more info about new species, updated names and so on share them! Regards

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?

While my prime focus is essentially learning how to accurately describe Nature in the precise language of mathematics, I've always been intrigued by natural history - it's actually what started me on the path to physics. The sort of interrogation that paleontology practices provoked me to think and question even further, down to the fundamental science which makes it all work. Collecting fossils has brought a large amount of enjoyment to my life, and is often a welcome distraction from what can sometimes be straining work. The knowledge that I accumulate along the way is also part of the fun. Here is my collection, which will always be a work-in-progress. There's still many things I haven't photographed yet, but I feel comfortable saying this is the majority. I don't have many big things, but I'm certainly pleased with the many small things I have so far. Links to albums: Dinosaurs Sharks North Sulphur River Post Oak Creek Permian Aguja Formation Harding Sandstone Devonian Galveston Fossils Miscellaneous Highlights / Personal Favorites: The ones underlined are linked to their respective fossil page in the Fossil Forum Collections, which has more information and photos. Infant Tyrannosaurus rex posterior tooth If I could keep only one fossil, it would be this one. It's from my favorite animal that has ever lived, and being from a young'un is just so darn cool. A true crowning jewel in my eyes. Juvenile Tyrannosaurus rex maxillary tooth Again, you can't go wrong with T. rex. It doesn't have the best preservation but regardless, there's a lot more to love. Tylosaurus proriger tooth (self-found) Undoubtedly my favorite find to-date. Finding fossils yourself adds that extra value to its place in your collection. I'll remember the moment I first saw it for a long time. Triceratops prorsus tooth Triceratops is another one of my favorite dinosaurs, I think we all grew up playing with toys of T. rex and Triceratops. Unique circumstances also allow for me to say it's Triceratops and not Torosaurus with some confidence. It's not perfect, but still a significant part of the collection. Avisaurus archibaldi tooth A bird tooth? Doesn't get much cooler or more uncommon. Dimetrodon cf. limbatus tooth I've always been drawn to "icons of life," since those are the ones we remember from childhood. Dimetrodon is definitely an icon, and I'm glad to have found one of these uncommon treasures (in micromatrix - it was a very nice surprise). Cretoxyrhina mantelli tooth One of my favorite shark species, the "ginsu" had sleek-looking teeth, ate mosasaurs and dinosaurs, and was overall a formidable animal worthy of admiration. Cretodus crassidens tooth (self-found) Another one of my favorite sharks. It's not big or complete, but the preservation is so rare for the locality (POC) - the gloss on the enamel is as if it fell out of the shark's mouth yesterday. Saurornitholestes langstoni tooth I'm currently working on growing the dinosaur component of my collection, and this is my first Dromaeosaurid. Dromaeosaur tooth (Hell Creek Fm.) My most recent addition (as of Sept. 4, 2021), and it's my best dinosaur tooth for sure. Unfortunately it will be labeled as only a Dromaeosaurid tooth for now, but it still is just a great tooth from a cool family of dinosaurs. Shark Tooth Riker Display I've got one riker that I've tried to squeeze as many teeth into as possible. I need to get a couple more, probably; there's a lot of teeth that deserve a riker, but are just lying around. I'll try to update this thread semi-regularly as I make acquisitions in the future.
