Abstract

A new crinoid species of the family Hemicrinidae Rasmussen sensu Rasmussen (or Sclerocrinidae Jaekel sensu Hess), Hemicrinus klikushini sp. nov., is described from the Danian (early Palaeogene) of the Middle Vistula River valley in eastern Poland. It is characterized by a low cup of five narrow radials, two of which are larger and elongated. This cup is attached to an elongate proximal columnal. To date, the present find constitutes the youngest record of this genus and documents the presence of cyrtocrinid crinoids in a shallow-water environment. The systematic research of Cretaceous Hemicrinus species is reviewed.
