Mosasaurus or Something Else?

[MaximusTN]

Please help identity. Is this a mosasaur or something else? This tooth was found of the WM Browning Cretaceous Fossil park. This is shaped somewhat different than other mosasaur that I have found at the park (more slender and recurved). For example, this looks much different than the pterygoid tooth in my collection. 

 

Thanks for your insight.

Nice specimen.

 

Can you post photos with a scale for reference?

It's a croco

[Al Dente]

I think it's mosasaur. A photo of the bottom would help.

The tooth is just over 1 cm or just under 1/2 inch.

The elliptical pulp cavity is consistent with Mosasaur.

I agree with mosasaur.

Well I'm not familiair with the place itself but, I disagree with the others because of the size.
I think it's a perfect size croc tooth that are useally around 0,5cm to 1cm. Mosa's are around 2,5cm to 4 cm and that's the small ones.
There are different specie of ''flipper reptiles'' and if you know the exact time period you could look up the species that lived around this time. 
Lucky thing is the mosa (maashagendis) is well researched and the size range of there teeth can be found from every specie with detailed description of the shape.

Could be a mosasaur pterygoid tooth.

That would explain the curve and the small size.

It is indeed mosasaur, to echo the above.

I agree.

Mosasaur pterygoid teeth can be found much smaller than that. Size, alone, is too variable a characteristic to determine tooth ownership.

 

The shape, surface character, geology, and size suggest this is a mosasaur pterygoid tooth.

I wish my english was good enough so i could explain why this is a croc.
80% is mosa 10% croc 10% other flipper reptiles and this is certainly a croc.
Few months ago I have read close to 500 pages of research about the mosa and the sub species.
I'm not gonna argue about it because it's not worth it to explain it for a single tooth.

I agree with mosasaur pterygoid tooth.

Pterygoid tooth seems legit.  Here is a sample.
