Reconstruction of A. grandis (top), with megalodon (bottom) for comparison
Alopias grandis is a species of giant thresher shark from the Miocene. Estimates calculated from teeth comparisons suggest the living animal was comparable in size to the extant great white shark.[3] Remains generally consist of teeth, which have been found in the United States in the Calvert Formation of Virginia and Maryland,[4] and in Beaufort County, South Carolina.[3] They have also been found in the Miocene of Malta.[5] It is unlikely it possessed the elongated tail lobe of modern thresher sharks.[3] Some specimens in the Burdigalian show the beginnings of serrations, which are presumably transitional individuals between A. grandis and A. palatasi.[5]
