First record of Dinocarida from Russia

Abstract

A fragment of a relatively large (on the Cambrian scale) animal, apparently a dinocarid, was discovered in bituminous shale of the Middle Cambrian Kuonamka Formation of the Olenek River near the village Olenek in northeastern Siberia. The exact taxonomic position of the specimen cannot be determined because of to its incompleteness, but it does not seem to belong to any previously described dinocarid genus. © 2010 Pleiades Publishing, Ltd.
