Nice finds. I've seen these teeth identified as Champsosaurus many times. I have my doubts about it because they look so much like fish teeth. Here is a picture of a Champsosaurus skeleton with more typical reptilian teeth. Unfortunately the teeth on the skeleton look like reproductions.

Yeah it's hard to tell. When you search for the images of champsosaur teeth online fossils similar to mine show up. However I did see some PDF on Hell Creek fossil ID a while ago which I believe was from a reliable source. I'll try to find it. The point being is that the teeth said to be champsosaur there also resembled mine.

The website isn't letting me post the last 2 photos because each of them are larger than 3.95 mb even after a number of attempts at resizing the images.

This tooth is best described as Ceratopsian indet.   There are other large bodied ceratopsians in the Hell Creek like Torosaurus and at least two unnamed Skulls that their owners believe are new species.

A paper I read that examined the Croc and Alligator teeth in the Hell Creek indicated that you cannot distinguish anterior teeth of Borealosuchus and Brachychampsa

These teeth are from the Amiid Fish Melvius thomasi very common in late cretaceous deposits

 

Paper

Melvius.pdf

 

Champsosaurs teeth are very different and have strong ridges at the base and are conical and narrow.  Here is a jaw in a publication I have describing the ostelogy of Champsosaurus.  I also have an unprepped jaw with a few teeth see below

Thanks, after looking at those teeth it's clear that's what mine are. When looking online for pictures of champsosaur teeth, the ones being sold are regularly misidentified and appear to be Melvius as well. On my most recent trip (stay tuned for a report later on this week) I found a section of jaw which the guide identified as champsosaur and it had an unerupted tooth still embedded which resembled the ones in your pictures.

Yeah I didn't really think you could with the normal looking teeth, I generally refer to that variety as Borealosuchus even though they are likely indistinguishable. I always refer to the bulbous teeth (Fossil 1. on this post for example) as brachychampsa, along with the molar like teeth which I'm pretty sure are unique to brachychampsa or close relatives in the late cretaceous of Laramidia.
