Weirdly closely packed (mosasaur?) teeth in moroccan jaw

[Brevicollis]

Hello, as I was scrolling throug some already sold pieces on different fossil websites, this interesting jaw caught my attention. It was listed as Halisaurus arambourgi, but I've never seen so many teeth so closely packed together in any mosasaur's jaws. Is it really mosasaurian ? Or a fish of some sort ? If so, which species had teeth packed so closely together ?

I dont really know, but it kinda reminded me of Xenodens calminechari because of these closely packed teeth tho, but these look completly different from the Holotype of this species. Has anyone an Idea ?

@Praefectus, are you able to help here ?

Thanks, any help is appreciated !

 

Sice : 5,4 cm long

Formation : Oulad abdun basin, Qued zem, morocco.

fish ,perhaps cybium dumonti ypresian

Definitely doesn't look like mosasaur. The root structures are all wrong for that. Besides, it'd be very strange to have so many teeth so well preserved with their roots, but not have any remnants of jaw at all. No, I'd agree this is fish. Just don't know what type... 🤷🏻‍♂️

I'm pretty sure that's some sort of fish jaw.

it can be just a enchodus jaw.
