Cretoxyrhina mantelli, Arcadia Park

Update: Reidentified as Cretalamna hattini after some more research. Welton and Farish previously misidentified Arcadia Park teeth as Cretalamna woodwardi. Siversson believes these to belong to the C. hattini-species group which contains C. hattini and C. deschutteri.  

I think I got the species mixed up previously, this looks closer to C. deschutteri.
