Abstract
Nuculoids constitute a group of bivalves with simple shell, taxodont teeth, protobranch gills and enlarged foot. They are evolutionary and phylogenetically very important because they represent one of root lineages of the bivalve evolution. This paper presents the revision of nuculids from the Šárka Formation (Darriwilian, Middle Ordovician) including genera Ctenodonta, Praeleda, Praenucula, Pseudocyrtodonta.
