Abstract

Two new trilobite species of the genus Oryctocephalus Walcott, 1886, Oryctocephalus doliiformis sp. nov. and Oryctocephalus molodoensis sp. nov., are described from the Amginian Stage of the Middle Cambrian of the Siberian Platform. They were found in the middle part of the Kuonamka Formation in sections on the Molodo and Muna rivers.
