Arctohungarites

Arctohungarites is a genus of Triassic ammonoids now placed in the ceratitid family Danubitidae, but previously included in the Hungeritidae.

The shell of Arctohungerites is subdiscoidal, involute, with a rounded venter, weak sigmoidal folds on the body chamber and a distinct ventral keel on the distal end of the chambered portion. The suture is ceratitic.

Arctohungerites was found in Middle Triassic (Anisian) sediments in northern Siberia
