Description
Extant frilled shark, Chlamydoselachus anguineus, is the most primitive shark in living elasmobranchs based on their anatomical characteristics. Based on the former data, the oldest record of chlamydoselachidae was Chlamydoselachus thomsoni reported from the Campanian (Late Cretaceous) of James Ross Island, Antarctica. In this paper, six species of twelve specimens of Chlamydoselachus from Japan, that is, five species of ten specimens from the Turonian to Maastrichtian, Upper Cretaceous formations and one species of two specimens from the Miocene, Tertiary formations are described and phylogenetic relationships and paleoenvironmental changes of chlamydoselachians are considered.
