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.

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!

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?

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.

How composite is this composite mosasaurus skull?
LordWampa posted a topic in Is It Real? How to Recognize Fossil Fabrications
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!- 5 replies

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!

Species level identification obtained from facet count (3-5 prisms labially; ~5 or indistinguishable lingually). See more information in Rempert et al. 2022 - Occurrence of Mosasaurus hoffmannii Mantell, 1829 (Squamata, Mosasauridae) in the Maastrichtian Phosphates of Morocco.

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".

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.
