Quinnites Manger and Saunders, 1980 |
Quinnites is a genus of goniatitid ammonites included in the gastrioceratoidean family Reticuloceratidae known from the Carboniferous of the state of Arkansas, USA. [1]
Quinnites can be recognized by its thickly discoidal shell with a wide umbilicus and double pronged ventral lobe with a median saddle about half as high as the entire lobe. Umbilical ribs are common. May have spiral ornamentation, constrictions, or ventral groove. [2]
Quinnites, named by Manger and Saunders 1980, contains two species, Quinnites henbesti and Quinnites textum, both removed from Gastrioceras ( Branneroceras).
