Does not appear human.
Appears worked on root end as well, so not a casual piece.. A starting point might be local creatures existing during approximate age of recoveries at site. Stuff traveled and was traded though...
Resembles no teeth I am familiar with in my area.
First uneducated guess would be that it is antler. Never checked gator teeth or wild hogs, domestic hogs been a long time, but similar yet smaller.... but if a tooth I would check small porcine tusks. No root showing or hole for nerve throws me off though.
