Metacarcinus is a genus of crabs formerly included in the genus Cancer.^[1] It includes nine exclusively fossil species and five extant species, of which four are also known from the fossil record.^[2] A molecular study using the cytochrome oxidase I gene does not support the monophyly of this genus.^[3]
