SENIOR, J. R. 1977. The Jurassic ammonite Bredyia Buckman. Palaeontology, 20, 3, 675–693.
J. R. Senior The lower Aalenian (Middle Jurassic) ammonite Bredyia subinsignis (Oppel, 1856) has been investigated at several growth stages and found to be dimorphic. Burtonia crassornata Buckman (1910a), the type species of Bredyia Buckman (19106), is regarded as a junior synonym of Ammonites subinsignis Oppel (1856) as are Hammatoceras newtoni Buckman (1892), H.feugeurollense Brasil (1893), and several species described by Dumortier (1874).
