Found in dig piles at Aurora Fossil Museum this week. Looks like possibly a tooth and has some resemblance to Hadosaur however that would be unusual since Lee Creek is Eocene as best I know.
Has a smooth rounded side (1st photo) and other side has a this raised edge that looks like it might have broken from another piece or maybe just worn down. One end is tapered to a point and the other is round but appears broken off. Photo 2 & 3 are the pointed end and 4 is the round end (approx 1/4" dia and 3/4" length.
ID??
