Oxfordian, marine reptile tooth fossil

[Flanker]

Hello everyone,

 

Last year I have found a fossil tooth, which I (at first) thought could be an interesting shark tooth fossil - since shark teeth are very abundant in this locality. It is just about 10 mm long, but as I looked at it later, I thought that it must be marine reptile fossil. At home I took my micro-camera and took some detailed photos with some small maginification. Then I was sure it is not a shark tooth. but something else. 

 

I have discussed this finding with Daniel Madzia and his answer was that it possibly belongs to Plesiosauria sp., Ichthyosaurus or Crocodylomorpha. He is teropod expert though and suggested me to ask someone who is into marine reptiles. Could you please help me with identification ? Thank you very much.

Lenght: 10mm.

Unevenly striated, slightly curved, cone-shaped.
Circular cross-section.
 

Age: upper jurassic, oxfordian
Site: Brno Hády quarry (Moravia, Czech republic, central Europe)

I'm no expert but looks like small Mosasaur to me...

I'm thinking plesiosaur but sometimes I shouldn't think according to my wife...

I'm wondering, if it couldn't be a pliosaurid tooth crown.
