Morocco keeps delivering cool new discoveries.   A new small Mosasaur is described in the attached publication, its Xenodens calminechari from the upper Maastrichtian phosphates of Morocco.

Teeth form a unique dental battery in which short, laterally compressed and hooked teeth formed a saw-like blade.

Has anyone seen teeth like these or have them in their collection?

I have never seen any of these teeth. 

Even on one of the biggest fossils shows in Europe (The Munich Show) with several seller form Morocco and lots of Mosasaur stuff, I have never seen such teeth.

 

Very interesting!

I have also not seen anything close to this at the Tucson show but its something I will look out for if its held this Spring.   Size probably precludes sellers from putting them in the Mosasaur teeth trays more in the shark ones.

Fascinating. Hopefully more Moroccan publications will come soon, especially with many of the unidentified teeth and bones so often found there.

Very few publications exist because most of the bones and teeth found are not articulated so it make identification very difficult on isolated material.    Its been a slow process with new discoveries.

Someone uploaded a copy of the preprint online, would it be against TFF's copyright rules to post a link to it here?

hi

never see mosasaur like that, super work from the team . discoveries are monthly here in the different group of fossils present in phosphates, and some of them will be described after few years of traveling in different collections. discoveries need presence of specialists on a ground working with the locals fossils dealer everyday.

Found a picture of the teeth in higher resolution.

hi

i didnt have the publication yet, but on a picture of the teeth, if i compare with carinodens palistinicus for harrana formation Jordan, they look the same, same size and same morphology, d13,d12 ,d14 on a picture from the book :Fossils of the Harrana fauna and the adjacent areas, Kaddumi (2009),to me is a maxillary of carinodens belgicus. i wait more informations about.

hi

after reading carefully the publication, is don't see new specie, by using the okam razor,its more logic too be in presence of carinodens maxillary instead a new weird specie, the final conclusion is easy to realize, CT scan the deciduous teeth present on this maxillary will show the shape of the teeth, and i beat they will be carinodens shape...

i know the book of the Jordanian fossils is not accepted by some scientist,but ...the specimens show in this book exist and in his case ,i find the picture number 7 figure 28  p 52 show the right sequence in the position and shape of the teeth ,the size and the position ,fit  with xenodens.

after all that can be a new specie of carinodens, i m not for make species with isolated bones or tooth, personally.

what will be interesting its too find the exact place on the quarry from where come this maxillary, because next time they will dig there , we will see more carinodens material, each quarry represent a particulary biotope.

the publication stay interesting ,its at list the first official carinodens maxillary...

this point of view is personal and based on my field experience of the phosphates mines of morocco.

The closest thing I have to those teeth, is a small (1.3 cm) mosasaur tooth from Morocco. It is somewhat similar, but less laterally compressed than those of Xenodens. It is bulkier, and not as flattened. But it is very broad, unlike most mosasaur teeth I’ve seen. It’s also very recurved, even more so than most Prognathodon teeth.
I hadn’t quite seen any tooth like this one, until I heard and saw the teeth of the new mosasaur from Morocco.

I guess it depends on whether the preprint was shared by one of the article's authors, or was "illegally" made public. The location where the article has been shared may be indicative of whether sharing here is okay. In any case, I'd be interested in perusing that preprint ;)
