Could this be a new species of Ptychodus?

I have never seen/found one this large before.

If not, could anyone who is an expert in Ptychodus teeth give an ID?

Thank you! It was found in West Alabama.

Nope. Ptychodus mortoni:

Nice find! It has a significant feeding wear facet.

Nice size and specimen of Ptychodus mortoni.  Three other species may be found in Alabama:  Ptychodus martini, Ptychodus rugosus, and Ptychodus polygyrus.  But, these are likely very rare species to find there. Polygyrus has probably only been found in Alabama - not in the rest of the U.S.  It has been found more frequently in Europe.
