Rodzaj Discoclymenia Hyatt,, 1884

Gatunek typowy
Goniatites Haueri Münster, 1840 from the late Famennian of Franconia.

Opis

Diagnosis. — Suture with minute ventrolateral lobe and pointed tips of dorsolateral lobe and lateral saddle.

Remarks. — Alpinites Bogoslovsky, 1971, with Wedekindoceras kayseri Schindewolf, 1923 as the type species, and Discoclymenia represent (together with Gundolficeras, Exotornoceras, and Posttornoceras) successive grades in the probably monospecific lineage. Until more coeval (thus biological) species are recognized a moderately conservative approach to its taxonomy is thus proposed.
