Systematics of the Cretaceous-Paleogene chimaeroid fishes of the genus Elasmodus

, : Systematics of the Cretaceous-Paleogene chimaeroid fishes of the genus Elasmodus. Paleontologicheskii Zhurnal (3): 65-75, May-June

The genus Elasmodus comprises nine species including E. tsheganicus sp. nov. Elasmodus remains are known from the Albian-Eocene interval, predominantly from the Old World. Fossil material of this genus has been found in fourteen localities in Russia, Kazakhstan, Uzbekistan and Ukraine. The Elasmodus fishes were sclerophagous and had probably partially shifted towards vertebrate carrion feeding. The extinction of this genus was due to the global cooling and sea regression at the end of Eocene.
