Haravex Posted June 16, 2019 Share Posted June 16, 2019 I was offered this tooth it has serrations but it looks more mosasaur shaped. Any input is appreciated @LordTrilobite you have a decent amount of experience in dealing with mosasaur material correct? Link to comment Share on other sites More sharing options...
JarrodB Posted June 16, 2019 Share Posted June 16, 2019 It looks like a mosasaur tooth to me. 1 Link to comment Share on other sites More sharing options...
ynot Posted June 16, 2019 Share Posted June 16, 2019 Looks like mosasaur for Me too. 1 Darwin said: " Man sprang from monkeys." Will Rogers said: " Some of them didn't spring far enough."

gigantoraptor Posted June 16, 2019 Share Posted June 16, 2019 I do have a mosasaur tooth with tiny serrations. They do occur but are more often found without. 1 Link to comment Share on other sites More sharing options...
JarrodB Posted June 16, 2019 Share Posted June 16, 2019 Just now, Haravex said: Do some mosasaur have serrations? Well known mosasaur experts such as Polcyn have documented serrated carinae within the Mosasaurinae. Here's a quote from an article discussing it. The presence of carinal serrations in Prognathodon currii, P. overtoni, P. rapax, P. solvayi, and Plesiotylosaurus crassidens renders use of this feature equivocal (Bell, 1997; Christiansen and Bonde, 2002; Bardet et al., 2005a; Lindgren, 2009). These taxa share this feature with Eremiasaurus, Mosasaurus, and Plotosaurus, but not Globidens (Bell, 1997). Furthermore, if this can be interpreted as a loss of carinal serrations in Globidens due to extreme inflation of the tooth crowns (Bell, 1997), it is more parsimonious to assume that the presence of these dental features in Prognathodon and the plotosaurine mosasaurs are homologous characters that unite them to the exclusion of Globidens (contra Bell, 1997; Christiansen and Bonde, 2002; Schulp, 2006; Polcyn et al., 2010). Alternatively, the traditional hypothesis of a close relationship between Globidens and Prognathodon indicates at least two independent acquisitions of serrated carinae within the Mosasaurinae.

LordTrilobite Posted June 16, 2019 Share Posted June 16, 2019 Does indeed look like Mosasaur. Some mosasaurs have serrations on their teeth, some don't. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Haravex Posted June 16, 2019 Author Share Posted June 16, 2019 Thanks for all the help guys I really appreciate it I can identify pterosaur vertbrae and bones due to characteristics also I frequently handle fragments from the kem kem beds so there is an overlap of knowledge and experience, but reptiles I have no overlap in experience. Again thanks for all your help. 1 Link to comment Share on other sites More sharing options...
