HunterLacrosse Posted January 26 Share Posted January 26 (edited) hi I recently wanted to find a Tylosaurid tooth from Morocco, but I'm confused about the tooth morphology of this ID. Because I found that some teeth described as Tylosaurid had very distinct protruding prisms (likes figure 3 and 4) on their crown surfaces, while some teeth were indeed relatively smooth (picture 1 and 2). Which one is correct? Edited January 26 by HunterLacrosse error expression Link to comment Share on other sites More sharing options...

Which one is correct? If I understood correctly. You are looking for Tylosaurine from Morocco, species would be Hainosaurus boubker. It has different tooth morphology than Tylosaurus species. 1 There's no such thing as too many teeth. Link to comment Share on other sites More sharing options...

There's a notable difference in tooth morphology between Tylosaurus and Hainosaurus. While it's been a point of contention in the scientific community whether the genera are synonymous, the teeth are one of the aspects that, at least to us, indicate that they're not. 1 1 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...

So, in Morocco, there doesn't have Tylosaurus species? and some Tylosaurid teeth in here would belong to H. Boubker? thanks Link to comment Share on other sites More sharing options...

HunterLacrosse Posted February 2 Author Share Posted February 2 hi there In Morocco if the size of isolated tooth from Mosasaurus Hoffmannii is over 7 cm, it is still available to identify between M. hoffmannii and M.Beaugei? i heard someone said that it is too hard to identify if the height of isolated tooth is bigger than 7 cm. because the prism faces will become more obvious in the lingual side. is that true? or is there any nice method that can help us to identify accurately?

I'm not sure whether the cut off point is indeed a hard 7cm. However, larger teeth seem to show less clear ornamentation in terms of prism faces and faceting, which makes it difficult to distinguish between Mosasaurus beaugei and Mosasaurus hoffmannii, as these are exactly the criteria to look out for...! Throw individual variation into the mix, and the picture muddles even further... 1 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...

I'm not sure if what I understand is correct. you mean that the prism faces and faceting in the lingual side will become less obvious, if the size of isolated tooth is big enough? right?

Correct. Labial side too, though those would be prism faces rather than facets, which are found lingually in Mosasaurus. 1 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...

All I think it tells you is that these large teeth are extremely expensive nowadays, and the risk of it turning out to be M. beaugei high...

HunterLacrosse Posted February 3 Author Share Posted February 3 i saw someone posted this video online and labeled it as M. Hoffmannii. the size is pretty huge at around 8 cm, and the condition is also really nice. in my opinion, it is a mosasaurus sp. tooth, may belong to M.hoffmannii. however, I still prefer looking forward to your guys' suggestions.

A bit tricky due to the size and fact that this obfuscated prism faces and facets. At the same time, the way the light rolls across the labial side, suggests three, but probably four, prism faces, and, thereby, Mosasaurus beaugei. 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...

I have not seen Tylosaurus teeth on sale, but other members do own some. I think hardest part is to find seller who could get them. We just have to hope we have some luck someday. 1 There's no such thing as too many teeth. Link to comment Share on other sites More sharing options...
