Liparoceratidae is a family of eoderoceratacean ammonites from the Lower Jurassic that combines genera with a variety of forms including dimorphs that change from one form to another during ontogeny. Three genera and six subgenera are included in the Liparoceridae according to D.T. Donovan in Donovan et al. 1981; Liparoceras including L. (Liparoceras), L. (Becheiceras), and L. (Vicininodiceras); Aegoceras including A. (Aegoceras), A. (Beaniceras), and A. (Oistoceras); and Androgynoceras. Arkell, et al. (1957) in the Treatise on Invertebrate Paleontology, Part L list Liparoceras with Becheiceras and Vincininodiceras along with Parinodiceras separately as subgenera; Beaniceras, Metacymbites, Oistoceras, and Platynoticeras but leave out Aegoceras. Parinodiceras and its equivalent, Platynotice
