Lissoceras is an involute, smoothly or finely vetrolaterally ribbed ammonite with a blunt, un-keeled venter included in the Haploceratidaefamily that lived from the Lower Bajocian to Middle Oxfordian (Middle to Upper Jurassic) ages in what is now Europe, south Asia, and southern Alaska.[2]
Lissoceratoides, once considered to be a subgenus of Lissoceras, is indistinguishable morphologically from it.
