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.

hi

its a pluridens walkeri, nasal bone, so its halisaurus walkeri premaxillary. for the moment nobody studied this specie on moroccans phosphates...

  • I found this Informative 4

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.

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...

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.

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!

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:
