Is this a baby mosasaur tooth?

[Deinocheirusmaster!]

I bought a chunk of sediment from Morroco from a fossil dealer a couple of months ago and I found some shark teeth, shark vertebra and this mosasaur tooth. What’s really interesting is that it’s extremely small. It’s a little bit bigger than my pinkie nail. Could this be a baby mosasaur tooth. 

(Note that I had some repair done to it.)

Yes I would call it mosasaur, nice small tooth

Yup, mosasaur. Possibly Mosasaurus sp.

Mosasaur tooth -yes, but "baby" tooth is debatable, because mosasaur regrow their teeth on a regular basis.

Some species are of a smaller variety also.

that wouldn't be small by east coast of USA standards. (not exactly large either). Attached a pdf of a set of loosely associated teeth from the Peedee formation. I believe the smaller more curved ones are from the roof of the mouth. Please note that I said loosely associated. I believe that most of these are from the same individual but there's no way to be certain. they are not from a lag concentration.

Used to, anyway (unless you've been holding out on us).
