Abstract

A new lamellorthoceratid genus, Plicatoceras, is defined on the basis of Plicatoceras nishidai n. sp. from the early Gedinnian shale of the Fukuji Formation in central Japan. The new genus is the earliest known member of the Lamellorthoceratidae and is the first record of a lamellorthoceratid cephalopod from East Asia.
