摘要
Abstract
A new genus and species Voroneceras rai gen. et sp. nov. (Cephalopoda, Nautiloidea) is described from the Famennian, Eletsian Regional Substage of the Lipetsk Region (Russia). Morphological analysis of the siphuncle structure supports the assignment of this new form to the family Westonoceratidae Teichert, order Discosorida.
