Abstract

An ophiuroid faunule, consisting of several articulated discs and numerous semiarticulated arm fragments, from the early Anisian (Middle Triassic) Waruishi Formation, Yakuno Group, in Kyoto Prefecture, central Japan, is described as Aplocoma sp. Insufficient preservation, in part due to incipient disintegration of the ophiuroid skeleton prior to burial, precludes a meaningful taxonomic interpretation at the species level. The Waruishi specimens represent the first Middle Triassic extra-Paleotethyan record of the genus Aplocoma and the oldest brittle-star body fossils from Japan to be described in detail.
