Help ID new year find! Mosasaur? Plesiosaur?

[Bob-ay]

Recent finds from my new year day adventure. Found these two teeth within 2 feet of one another. One I am confident in saying is a Mosasaur but the tooth on the right I need some help with! If anyone can shed some light it would be appreciated! Thanks

Plesiosaur is a good bet for the larger one. The smaller one os too beat up for me to make a confident ID, but mosasaur's a fair bet.

Thank you! Yes, trying to get a good ID on the larger one as I have nothing like it in my current collection. Hoping to be first Plesiosaur piece!

I'm really having trouble seeing the smaller one but am decently sure the bigger one is Plesiosaur.

 

I think better pictures should confirm.

Mosasaur + Plesiosaur

The larger one looks like a plesiosaur tooth to me too: it has the striations for it, lacks the carinae a crocodile tooth would have, doesn't have compression but does have a type of root that matches plesiosaur. Moreover, this tooth doesn't look like Enchodus to me as this would require the tooth to be more laterally compressed and show carinae. This thus rules out what I believe would be the most likely alternative interpretation.

 

The smaller tooth I'm hesitant to declare a mosasaur, as there isn't enough detail I can make out about it. Could be crocodilian as well. Better photographs from different angles and one from the top and base would be needed to help in identifying this specimen.
