Audaxlytoceras

Audaxlytoceras is an extinct genus of lytoceratid ammonites. The Middle Jurassic Nannolytoceras is its closest relative. Aegolytoceras and Peripleuroceras Tutcher and Trueman 1925 are synonyms. This genus is known in the fossil record from the Lower Jurassic (Pliensbachian) (from about 190.8 to 182.7 million years ago). Fossils of species within this genus have been found in France, Germany, Italy, Morocco and Spain. Its shell is 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.
