Parapopanoceras

Dienerites named by Mojsisovics,1902 Parapopanoceras is a ceratitid ammonite with a small, smooth, very involute and moderately globose shell that lived during the middle Triassic.

The suture is ceratitic with phylloid (leaf-like) saddles and subdivided lobes.

The siphuncle begins at a central or subcentral position and in most species becomes ventral at the end of the second whorl.

Closely related Stenopopanoceras differs in that its siphuncle starts off ventral.

Fossils have been found in Svalbard, Jan Mayen, British Columbia, the Russian Federation, and possibly Papua New Guinea.
