Paratirolites

Paratirolites is a genus of latest Permian and earliest Triassic ceratites from Armenia, Azerbaijan, Afghanistan, China and Iran with distinct ribs, prominent ventro-lateral tubercles, and a broadly arched venter.

The suture is ceratitic with a large ventral saddle.

[1][2][3] Ceratites are ammonoid cephalopods that lived during the Late Permian and Triassic.

Paratirolites is included in the Xenodiscoidean family Dzhulfitidae along with Abichites and Dzhulfites.

[4] Previously it was included in the Stephanitidae,[1] a family belonging to the Ceratitoidea.
