Cadomoceras is an extinct cephalopod genus from the order ammonitida that lived during the Bajocian Stage of the Middle Jurassic,[1] approximately 178 to 175 million years ago.
Cadamoceras has smooth inner whorls but the outer has course plications on the outer (ventral) flanks and across the venter. The aperture has a large scoop-like rostrum and spatulate lappets flanking either side. The suture is straight with small, widely separated lobes.
Cadamoceras, named by Munier-Chalmas in 1892, is a member of the ammonitid family Haploceratidae which is part of the superfamily Haplocerataceae.
