Abstract

Pseudocorax laevis (Leriche) is a Late Cretaceous anacoracid shark. Here, I describe the first associated teeth of P. laevis (along with unidentifiable fragments of calcified cartilage) from the Mooreville Chalk of Alabama. Although the specimen consists only of four teeth, morphological variation observed confirms the presence of heterodonty in the dentition of this taxon.
