A straight forward evolutionary sequence can be seen going from the [[ccephalopod shell morphology|cyrtoconic]] to [[cephalopod shell morphology|gyroconic]]''Aipoceras'' to the rapidly exanding [[cephalopod shell morphology|evolute]]''Asymptoceras'' and from ''Acanthonautilus'' with moderately curved [[siphuncle|septal necks]] and slightly examanded connecting rings to ''Solenochilus'' with strongly curved necks and well expanded conneciting rings (ibid K438,K441)
