Article: The enigmatic arthropod Duslia from the Ordovician of Czechoslovakia

A restudy of Duslia insignis Jahn, 1893 from the Upper Ordovician of the Barrandian area, Bohemia, indicates that this trilobate arthropod, originally referred to polyplacophorans, cannot be assigned to true trilobites but shows some morphological analogies with Cheloniellon, Pseudarthron, and Triopus. Duslia inhabited a nearshore shallow marine environment and was probably a benthic animal which lived buried in sandy substrate near the sediment-water interface.
