The Calvert Cliffs are a relatively continuous series of natural, m-( foot-) high outcrops along the western shore of the Chesapeake Bay in Calvert County, Maryland (Fig. 1).The Miocene strata exposed in these cliffs—the canonical Calvert, Choptank, and St.

Marys Formations (Shattuck,)—have been the focus of paleontologic and stratigraphic analysis since the late. Alopias palatasi ("Palatas' fox"), commonly referred to as the serrated giant thresher, is an extinct species of giant thresher shark that lived approximately to million years ago during the Miocene epoch, and is known for its uniquely serrated teeth.

It is only known from such isolated teeth, which are large and can measure up to an excess of 4 centimetres (2 in), equating to a Class: Chondrichthyes.
