Texas Paleozoic Shark/Chondrichthyan Tooth ID request

[Jaybot]

On a trip to TX, I managed to hunt in the Harpersville fm near Brownwood, TX.  I was excited to find this tooth, as Paleozoic sharks and fishes are a favorite of mine.  Collected on 10/6/24.

 

  Initially only the main cusp and the left cusplet was visible, so I prepped this tooth hoping for a cusplet on the right.

  Surprisingly, there ended up being a total of four cusplets, and the main ‘fang’ cusp.  The smaller cusps have a rounded point, which might be an identifying feature.

 

  I keep coming up blank with the ID for this tooth, and I feel like I’m going in circles.  Any help would be really appreciated!

 

Root is 4.3 mm wide:
