Unknown selachians from New Mexico's Coniacian Take 2

Apparently, two of my posts from yesterday didn't go through.  So here is Take 2.  It is a very small tooth as you can see.  It almost resembles a small pebble, but the crown is definitely enamel.  A person on the Cretaceous Shark and Marine Life group on Facebook suggested Brachyrhizodus ellipsis.  Is there any concurrence here?

Your site may be too old for B. ellipsis.  If that is a Brachyrhizodus tooth, it would be among the earliest forms.  It might be a Pseudohypolophus tooth.

I am leaning toward Pseudohypolophus, too, but it is extremely small!
