Tropigymnites

Tropigymnites is an evolute, discoidal ceratitid ammonite from the lower middle Triassic with somewhat overlapping whorls and sides with faint radial ribs, which converge on a narrow venter with a median keel. Sutures are weakly ammonitic with deep elements.

Tropigymnites is now assigned to the Gymnitidae which are included in the Pinacocerataceae, but previously included in the Celtitidae where with its keeled venter does not closely resemble the other genera included there.
