Titan Posted July 18, 2020 Share Posted July 18, 2020 Not sure if it will be helpful in this case, but here's a link to a PDF that helped me with some Mosasaur questions: https://www.google.com/url?q=http://peabody.yale.edu/sites/default/files/documents/scientific-publications/ypmB23_1967.pdf&sa=U&ved=2ahUKEwievu7ezdfqAhXIWc0KHaNjDHsQFjAAegQIARAB&usg=AOvVaw2kWQy2BFtQ6_8dLa0iPa-O 1 Link to comment Share on other sites More sharing options...
LordTrilobite Posted July 18, 2020 Share Posted July 18, 2020 It does look to be the premaxilla of a mosasaur. It looks a bit lumpy. Maybe it has a weird pathology? Halisaurus tends to have a more slender snout though. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...

jnoun11 Posted July 20, 2020 Share Posted July 20, 2020 hi its a pluridens walkeri, nasal bone, so its halisaurus walkeri premaxillary. for the moment nobody studied this specie on moroccans phosphates... 4 The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it.

Bonjour jnoun... I know English is not your native language, but in your statement here you call it two different bones AND two different animals. Is it a nasal or a premax? (It is a premax). Is it Halisaurus or Pluridens? Or is there a "not"missing? Thanks for clarifying. Link to comment Share on other sites More sharing options...
jnoun11 Posted July 22, 2020 Share Posted July 22, 2020 hi jpc its was pluridens walkeri too a new studie and now its considered : halisaurus walkeri, but... pluridens walkeri was found in niger and the specimen is a lower jaw with no tooth, in morocco we find complete skeletons or skull but nobody until today make studie about this incredible mosasaur, its the only one with 28 tooth on a dentary... more informations here 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.

LordTrilobite Posted July 23, 2020 Share Posted July 23, 2020 Yeah, Halisaurus walkeri and Pluridens walkeri is the same animal. Just a different name. As Jnoun says, it's not entirely clear if the animal belongs in the Halisaurus genus. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
pachy-pleuro-whatnot-odon Posted July 24, 2020 Share Posted July 24, 2020 If it truly is Halisaurus walkeri that'd be pretty special. It's definitely a premaxilary (part of the rostrum), but threw me off as it indeed does not look like Halisaurus arambourgi... And as to real or fake: obviously real. Cool fossil!

pachy-pleuro-whatnot-odon Posted July 26, 2020 Share Posted July 26, 2020 Just for sake of reference to anybody visiting this thread looking to either see what a H. arambourgi premaxilla looks like or compare it against H. walkeri, here are some images of H. arambourgi premaxilla: '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...
