Extinct genus of echinoderms
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]
