Some Post Oak Teeth; Pleistocene mammal, Hybodont, and Mosasaur(?)

[Thomas.Dodson]

I made a brief stop at Post Oak Creek traveling around Texas a couple weeks ago. I didn't have much luck searching for large fossils this time but looking small turned up some decent material, a few of which I wanted to request some identification help for.

 

First is this mammal tooth. I don't know how many people look into this small Pleistocene material. @Harry Pristis @Shellseeker, any ideas?

 

Next is this small mosasaur like tooth. It reminds me of some of the teeth that appear in a recent ID thread. @pachy-pleuro-whatnot-odon, any ideas on this one?

Trying to photograph the slight posterior carinae in this picture below.

 

Finally I've got this little tooth that looks like a Hybodontoid.

Your first tooth looks like river otter canine to me

Here is an interesting thread to read.... It also has an interesting groove in the enamel.

Your second tooth is not a mosasauroid, although it is a squamate: it's a Coniasaurus sp. tooth (though keep an eye on this thread in case I'm wrong). Excellent find, and something I'd still love to add to my collection! If you didn't sieve through matrix then you were either very lucky or have a good eye for it too

 

Love the seal canine too, by the way!

It is a small tooth, and it looks like a lower canine.  @Lorne Ledger's suggestion seems a more reasonable possibility.
