Endolobus is an extinct genus from the nautiloid order, Naulilida which includes Nautilus found living today. Endolubus is ncluded in the family Koninckioceratidae which is part of the superfamily Taintocerataceae. (Kummel 1964.K424)

The shell of Endolobus is an evolute spiral with whorl sections subelliptical; broadly rounded ventrally, narrowly rounded laterally, and slightly impressed dorsally (ibid) . There are low nodes on the flanks and the suture is slightly sinuus but with a prominent dorsal lobe. (Inside lobe, or endo-lobus) The siphuncle is small, subcental, and orthochoantic.

Endolobus has a range from the Lower Carboniferous (U Miss) to the Lower Permian and has been found in different locations in North America and eastern Europe.

Nautiloids are a subclass of shelled cephalopods that were once diverse and numerous but are now represented by only a handful of species.
