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.

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.

I echo Brennan's sentiments, Trevor, when I say this was an awesome project to have been involved in! It has been quite the ride, but it definitely paid off big! :fistbump:

Congrats to all of you guys, and a congratulations doesn't even feel like enough to say! :b_love1:  Ive been so excited about the news for days now. Its news like this that inspires me to pursue my dreams and fills my thoughts with so much enthusiastic wonder and curiosity what else is out there to find.
 

I bought one of the tees to support the project! I hope the chance come to where I can see the traveling exhibit. The name chosen is lovely. 
 

I love all of the fan art it already has on IG! :P

A new Moroccan Mosasaur Hainosaurus boubker is named here: First Record of a Tylosaurine Mosasaur from the Latest Cretaceous Phosphates of Morocco (scirp.org)

This is the first Tylosaurine named from the Maastrichtian of Morocco and the last occurring species of Tylosaurine named from anywhere; it is also unusual in occurring in warm waters.

The authors of the paper consider Hainosaurus to be a distinct genus separable from Tylosaurus with teeth adapted for cutting up prey.

I didn't know of this paper until now, but it indicates that the synonymy of Hainosaurus with Tylosaurus by Jimenez-Huidobro & Caldwell (2016) might be somewhat arbitrary due to the fact that a few tylosaurine species are known from the middle Campanian to Maastrichtian worldwide (the Taniwhasaurus type species T. oweni occurs in much younger deposits than other referred species of the genus, while Tylosaurus saskatchewanensis is the only Tylosaurus species from North America that comes from late Campanian deposits) and the possibility to shared dental and cranial characters between Tylosaurus and Hainosaurus being homoplastic for some derived tylosaurines. Indeed, Hornung et al. (2018) and Sachs et al. (2018) note a number of differences between the dentition of Tylosaurus and Hainosaurus that they regard as indicative of morphological diversity among Tylosaurus-like tylosaurines, suggesting that Hainosaurus may have been the most advanced derived tylosaurine.

More updates on Hainosaurus boubker, a talented artist Museum Miniatures has made several 3D models in different poses.

These help bring the species to life and show angles not often portrayed in traditional art.
