Genus: Lepidocystis

Lepidocystis is a Palaeozoic genus of imbricate lepidocystoid eocrinoid, closely related to Kinzercystis,[1][2] It bore a stalk, with which it attached to firm substrates;[3] and brachioles arising as lateral branches from its arms.[4]

It is only known from the late Botomian = Cambrian Series 2 Kinzers Formation.[5]
