Cadomites is an extinct ammonite genus from the superfamily Stephanocerataceae that lived during the Middle Jurassic (upper Bajocian – lower Callovian).[1]
Description
Cadomites is directly descended from Stephanoceras, with a similar collared and lipped aperture rim, but has denser, finer, sharper ribbing. The shell is discoidal, evolute, with a wide umbilicus. The suture is complex.
Distribution
Fossils of species within this genus have been found in the Middle Jurassic sediments in Europe, Africa and South Asia.
