I have this very tiny tyrannosaurid tooth from hell creek formation, south dakota. Im wondering if it's possible to know if the tooth is from a infant nano or t-rex? Distal serration density: about 6/mm Can't see any intact serrations on the mesial side. Crown Height: 4 mm Crown base-lenght: 2,5 mm Crown base-width: under 1 millimeter, about 0,8 mm to roughly estimate (very hard to measure this one).

I was on another river adventure and found this Butte. I tried to find images that resemble what I found, the closest comparable was a infant mastodon calf. I would appreciate any feedback y’all may have! Thanks!!
