jasonlwjy Posted February 10, 2022 Share Posted February 10, 2022 Hi, I am currently having trouble identiying this Morocco tooth, it's overall shape is similar to teeth of prognathodon anceps, but it also looks a bit angular and it has inequal buccal and lingual surface, which i think are not characteristics of prognathodon teeth. The photos of the teeth are posted below, could you help me figure out its specific genus or species? thank you so much! b 1 Link to comment Share on other sites More sharing options...

With the carinae being perfectly aligned with the anteroposterior axis, the tooth having a slight mesiodistal and negligible lingual curvature, as well as darker enamel near the tip indicative of durophagous adaptations, and, moreover, an overall robust shape, this is undeniably a tooth of Prognathodon giganteus/anceps/sp.. Tylosaurine teeth would be more laterally compressed and have significant mesiodistal curvature, whereas in Mosasaurus the cross-section would be way less symmetrical labiolingually. 3 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...

TyrannosaurusRex Posted February 10, 2022 Share Posted February 10, 2022 I’ve come back to this topic many times, and I’d love to get peoples opinions on what these two mosasaurs might be. The jaw section reminds me of Globidens teeth, but they’re not flattened/rounded enough and are too elongated. This one seems similar to Platecarpus, but I was told that the teeth are not elongated/thin enough for this to be the case. Very peculiar mosasaur teeth, I haven’t come across any teeth similar to this. Comparably, it’s definitely different from my Platecarpus teeth and jaw, and very different from all the loose mosasaur teeth I own. Link to comment Share on other sites More sharing options...

Although in a very bad state and better pictures, especially in the axial and occlusional planes, would be necessary to confirm, I'd say at first glance this looks like Carinodens belgicus to me. With their teeth being rare, their jaws are even more so.

You can tell by how sterile of other fossils the matrix around the "skull" looks. Real bits and pieces of mosasaur have been used, that's true, but the overall composition is an artwork. As such, it's unlikely the teeth all belong together, although they do appear to be of a consistent morphology. With not much of that even to go on, their facetted nature, to me, suggests Mosasaurus beaugei. 3 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...

That’s really interesting, it’s not a species I’m familiar with. The partial skull I actually do not believe is fabricated, not from the seller in Tucson I purchased it from. I won’t name names here, but he’s not someone who would sell fake stuff. It’s stuff he collects and he’s very reputable, and I know people who have visited his site in Morocco where it was collected. I’m in the process of removing it from the plaster jacket, and I’ve had no issues with doing so thus far that would indicate it’s lack of authenticity. I do really appreciate the comment though!

I agree with Alexander. Based on your image of the "skull", it looks like a 'frankensteined' imitation. Bear in mind, even "reputable" dealers can be mistaken at times.

jnoun11 Posted March 24, 2022 Author Share Posted March 24, 2022 hi its look not compressed so its not carinodens: i just find something looking like your teeth. that can be a pachyvaranus or some new globidensini. 2 The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it.

LeeB Posted August 28, 2022 Share Posted August 28, 2022 There is a new Moroccan mosasaur here: Thalassotitan atrox, a giant predatory mosasaurid (Squamata) from the Upper Maastrichtian Phosphates of Morocco - ScienceDirect It is an apex predator related to a couple of Prognathodon species; I wonder if they will eventually get moved to this new Genus?

Yup, that's what it looks like. There is so much morphological diversity in Prognathodon anceps and researchers have been so inconsistent in their naming of ornamental features in their dentition that a lot of confusion arose on how many and what species of Prognathodon actually occurred in Morocco. Rather than go into lengthy discussions with all parties involved to sort out that mess, it seems that Longrich, Bardet and consortium opted to just define a new species that would override all the confusion...

It doesn't match with the Solvayi post @jnoun11 @pachy-pleuro-whatnot-odon The second photograph of the first tooth is quite informative as to it's identification. In this photograph you can clearly tell that the tooth has a slight twist in the plane defined by the two paired carinae, making the tooth curve mediodistally. This is a feature that marks this tooth as Mosasaurus. The strong facetting, moreover, makes it clear that it's M. beaugei rather than M. hoffmannii. The second tooth, however, is most likely prognathodontid, seeing as there's no clear mediodistal curvature but the curve, instead, seems to run distally only. And while there seem to be few durophagous adaptations in this particular specimen, the facetting is also too prominent for a tylosaur. 1 'There's nothing like millions of years of really frustrating trial and error to give a species moral fibre and, in some cases, backbone' -- Terry Pratchett Link to comment Share on other sites More sharing options...
