Dimorphoceras ( Dimorphoceras ) kathleenae Moore and Kazakhoceras hawkinsi (Moore) are also recorded from the same zone. An early variety, var. leitrim… Show more

“…-Metadimorphoceras richardsi belongs to the simple-sutured species of the genus (Manger 1988), showing a degree of complexity comparable to the late Asbian (British P 1 a Zone) M. pseudodiscrepans (Moore, 1939), which, however, already shows a further subdivision of the external lobe. A similar complexity stage, but also with a weak tertiary subdivision of the external lobe, is visible in the early Brigantian M. hodsoni Moore, 1958. This shows that M. richardsi obviously represents a very early stage in the diversification of the genus Metadimorphoceras.…”
