Thefossilman92 Posted June 4, 2019 Share Posted June 4, 2019 Hi! I have a handfull of croc teeth from kem kem , and I would like to learn more about identifying these croc teeth. I know that it can be hard to id these teeth but I was wondering if someone got some papers where most of the discoveries of moroccan crocs are illustrated? , I´ve been trying to find some but with no luck, I just found some papers that only describes Elosuchus.

jnoun11 Posted June 4, 2019 Share Posted June 4, 2019 in kem kem beds we have a small crocodile of the family Trematochampsidae: hammadosuchus rebouli, a stomatosuchid: Laganosuchus maghrebiensis an elosuchid: Elosuchus cherifiensis. Elosuchus is called before thoracosaurus, named by rene Lavocat in 1955, then correct again in 2002 by the Museum of Natural History of Paris. a small internet link: http://www.sesne.fr/maroc_2010.pdf https://docplayer.fr/51068541-Elosuchus-a-new-genus-of-crocodile-from-the-lower-cretaceous-of-the-north-of-africa.html https://peerj.com/articles/759.pdf https://www.academia.edu/29839427/A_new_sebecosuchian_crocodyliform_from_the_Late_Cretaceous_of_Patagonia KELLNER A.W.A. & MADER B.J., 1997.

gigantoraptor Posted June 4, 2019 Share Posted June 4, 2019 I am aware of 7 described Crocodyliformes in the Kem Kem beds. - Lavocatchampsa sigogneaurussellae - KemKemia auditorei , no teeth of this species are known, only caudal vertebra. - Aegisuchus witmeri Don't have anything about these teeth. - Araripesuchus rattoides teeth should look like this. - Elosuchus cherifiensis teeth can sometimes be identified by their huge size. - Hamadasuchus rebouli - Laganosuchus maghrebensis 2 Link to comment Share on other sites More sharing options...
RuMert Posted June 4, 2019 Share Posted June 4, 2019 Sorry for a newb question, but how do you distinguish crocodile teeth from ichthyosaur/plesiosaur? 1 My sites & reports Link to comment Share on other sites More sharing options...

Hi Yury, I'm sure you are aware of this by now, but let me answer this just for others that might find their way here: - Neither ichthyosaurs nor plesiosaur typically have carinae, whereas crocodilians typically do. - Ichthyosaurian teeth have rounded enamel-folds on their tooth crowns (known as plicidentine), which sets their teeth apart from the more crisp/squared striations of both crocodilians and plesiosaurians. These enamel-folds, moreover, contrary to crocodilian and plesiosaurian striations, are very consistent in width and height. - The roots of ichthyosaurs can be anywhere from rounded through triangular to rectangular in shape (as their teeth are not individually socketed, but instead sit in a tooth-groove), and may exhibit folding, much like their tooth crowns. In contrast, the roots of crocodilian and plesiosaurian teeth are round and pen-like/tubercular, with pliosaurian teeth supposedly having a bulge directly underneath the tooth crown. - Sometimes it's a matter of geological context: ichthyosaurs and plesiosaurs were only around during the Mesozoic, and almost exclusively (with some exceptions amongst Cretaceous plesiosaurs) occur in marine sediments. 2 '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...
