Until recently,the only known fossils of this animal are the teeth, which were arranged in a "tooth-whorl" strongly reminiscent of a circular saw. H. mexicanus, From the time of Hay’s paper (1912) until the present, paleontologists have assumed that the tooth whorls of Helicoprion and similar dentitions in other edestoids were jaw dentitions (see Zangerl, 1981:86), but no skeletal evidence existed to support their position. Due to the fossils' locations, the various species of Helicoprion may have lived off the southwestern coast of Gondwana, and later, Pangaea. the 1880s that this giant, bizarre creature was discovered for the first time It was named in 1899 by Alexander Karpinsky.
