Paratirolites is a genus of Early Triassic ceratites from Armenia and Iran with distinct ribs, prominent ventro-lateral tubercles, and a broadly arched venter. The suture is ceratitic with a large ventral saddle.[1] Ceratites are ammonoid cephalopods that lived during the Late Permian and Triassic.
Paratirolites is included in the Xenodiscacean family Dzhulfitidae along with Abichites and Dzhulfites.[2] Previously it was included in the Stephanitidae,[1] a family belonging to the Ceratitaceae.
Species of Tirolites have also been found in the Upper Permian of Azerbaijan, Thailand and Japan. and in the Triassic of Axerbaijan and Afghanistan.[2]
