Audaxlytoceras is an extinct lytoceratid from the Lower Jurassic. Its shell small, smooth, evolute (all whorls showing), only slightly impressed dorsally (along the inner rim). Whorls are compressed, subquadrate in section, higher than wide, with few narrow constrictions. The suture relatively simple with a long ventral lobe and two lateral lobes.

The Middle Jurassic Nannolytoceras is its closest relative
