Berriasella has a highly
developed process. The ammonites have separate sexes and in some cases they
display a marked sexual dimorphism, in which micro- and macroconchas are
represented that respectively had to correspond to males and females. Adult
microconchas develop lateral processes; instead, adult macroconchas maintain a
shell with simple peristoma.
