Hybodus tooth from North Carolina U.S.A.

[fossil_lover_2277]

Is this a hybodus tooth? 1cm tip-to-base, Black Creek group of North Carolina U.S.A.

[ThePhysicist]

It does look Hybodontid with the striations and flaring-out at the base of the crown. It's a bit broader than I'm used to, but E/F in the below figure convinced me it was within the range of variation.

 

^ Cicimurri et al. (2014)

 

If I'm not mistaken, all (if not most) Hybodus species in N. America were reassigned to Meristodonoides.

EDIT: This has already been specified above, I missed that before I posted

 

With that width for a hybodont consider Meristodonoides.

 

Campanian Meristodonoides novojersayensis from North Carolina.

@Jared C is correct. M. novojerseyensis is the correct I.D.

Is there a publication listing this genus and species? Googled it and literally nothing came up except this one post.
