Dactylioceras is highly evolute and has strong slightly inclined forward ribs. The ribs run over the venter and sometimes fork on its outer edge.
Dactylioceras commune can be distinguished by its almost perfectly round whorl section. The fine ribbing in the inner whorls becomes sparser on the outer whorls. The ribs run almost straight on the venter.
