Abstract

A new genus and species of the small echinoderm class Parablastoidea, with an unusual starshaped theca, from the Middle Ordovician of the lower reaches of the Volkhov River is described. Functional features of its food-gathering system, the origin and functional role of the ambulacral and oral crests are discussed.
