Hemi placement?

Recommended Posts

I found this very tiny hemi a while back (Brownies beach). I was wondering if anyone could tell me the placement? This is the whole tooth (but it’s rootless) not the top of it. Thanks.

Elasmo.com has some nice views of renditions

Thanks to both of you! I think that’s right. Going into the tiny posteriors bag.

If you believe Compagno 1988 the extant Hemipristis elongatus only has a single upper posterior tooth (see below) and two lower posterior teeth (see below).  Assuming H. serra had a similar dentition, your tooth would be an upper lateral.
