''Anoploceras'' is a genus of Middle and Upper Triassic nautiloids included in the Tainoceratidae, known from eastern Europe. The shell is evolute with only a slight overlap of previous whorls. Whorl section is subquadrate, like '' Pleuronautilus'', only depressed. Flanks have conspicuous ribs that may be somewhat sinuous. '' Holconautilus'' has a more rounded venter, and flanks, and is more evolute. '' Enoploceras'' has weaker ribs that expand into nodes on the umbilical and ventro-lateral shoulders, and a small umbilical perforation. '' Encoiloceras'' has strong ribbing, a large umbilical perforation, and a shallow groove along the venter.
