Elasmosaurus?

[Bolgorcut]

Hi,

I bought this tooth labeled as: "Tooth of Elasmosaurus K2 Cretacerous. Albian stage, Stariy Oscol, Russia." (I wrote it as written in the label they gave me)

Now, the genus Elasmosaurus should be from The Campanian period.

My questions are:

Is this an Elasmosaurus tooth?

Could they mean Elasmosauridae without specifying the genus?

If it is not Elasmosaurus platyurus, can you tell me, if possible, what species or genus it is?

Thank you.

Seems a bit short and stout compared to the ones I’ve seen, but I’m no expert
