 The subgeneric name was derived from Greek σοῦχος, "souchos", the name of the Egyptian crocodile god Sobek.This reflected the presumed taxonomic affinities; at the time the crocodile-like snouts of spinosaurids were not known.The specific name is derived from Latin "culter", "dagger", and "dens", "tooth", in reference to the elongated form of the teeth.
