I believe I have made quite well with collecting Moroccan mosasaurs, so I wish to set my eyes for new goals. And first US mosasaur material is already heading its way. I have been hoping to learn more about American mosasaurs in general and also basic tooth characteristic of more common species. Only one Im relatively familiar with is Tylosaurus proriger. With Platecarpus tympaniticus only by few articles. I managed to find information about most formations where material seem to come from, but not Ozan fm. What species were present besides Tylosaurus proriger? Thanks for replies.

Introducing Hainosaurus boubker, Last of the Great Tylosaurs.
Praefectus posted a topic in Fossil News
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.

From the album: Texas Campanian (Cretaceous)
Tylosaurus cf. proriger Campanian Texas Ozan fm Tylosaur tooth found in gravel. I'm of the opinion that perhaps the assignment of T. proriger to the Ozan Tylosaurs is hasty - though it's difficult since the obvious differences between these and the holotype are restricted to a single cranial element. Not sure I should say much more on that - while it's not an existing research question it's not my original observation. -

Looking for American/European mosasaur Jaw & teeth
JorisVV posted a topic in Member-to-Member Fossil Trades
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! -
I look to 2 teeth. I like to ID then before buying. Is the first one Tylosaur (1.00”) and the second one clidates (0.84" (2.15 cm) ? Both from the Eutaw Formation of Prentiss County

From the album: Squamates
A tooth from a large mosasaur that inhabited the Western Interior Seaway during the Late Cretaceous. Tylosaurus was an apex predator with thick teeth that allowed it to predate on anything in its ecosystem from large turtles to sharks. This particular tooth has clear feeding wear on the tip.- 2 comments

Can someone help me identify this fossil vertebra I found in Montgomery?
-
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.

This post series will attempt to illustrate a minor prep project of a Moroccan mosasaur fossil. It is hoped it will encourage others to attempt a similar project, using simple tools. Thanks to Forum members @DPS Ammonite and @LordTrilobite for their helpful pre-acquisition comments. Special thanks to @jnoun11 for his ID verification of the piece and clarification of the fossil's precise place of origin. The Moroccan seller listed the fossil simply as "Mosasaur, 9 cm X 6.5 cm, Cretaceous, Khouribga, Morocco" Here is a photo from the seller. Note the large coprolite resting beneath the rearmost tooth. Unfortunately and not unexpectedly, the piece arrived damaged. At first glance it did not appear too severe. However close inspection revealed cracks in the matrix that ran to and beneath the two rear teeth. As an interesting aside, the break in the coprolite revealed an internal color pattern. To be continued.....
