Teeth ID help

[krisnicole82]

The following pictures were found in a cave on my farm in central Kentucky. They were deeply buried underwater and rocks at the mouth of the cave. Water flows heavily from the cave and rocks had been clogging the waterfall so we were trying to clean the area up. Thank you in advance

The first appears mammalian and the last is a heavily worn shark tooth. I don’t handle those types regularly, so that’s as specific as I feel comfortable getting before someone who does handle them more often offers a more precise ID.
