Reference	Diagnosis
K. A. v. Zittel 1884	2. Unterordnung: Ammonoidea. Shell is usually spirally rolled, disc-shaped, rarely very neck-shaped, evolute, curved, or straight. Mouth simple or with lateral and ventral processes. Suture line wavy, jagged or with slashed lobes and saddles. Siphon cylindrical, always at the edge, without internal deposits. The initial chamber is spherical or egg-shaped. Aptychus or Anaptychus present membranously.
