The discovery of late Cambrian fossils in the Bowers Group of Northern Victoria Land, Antarctica, provides the first reliable evidence for the age of basement sedimentary rocks in the region. Together with a previously reported fauna of generally similar over-all composition and age, from the Heritage Range of the Ellsworth Mountains on the opposite side of the continent, they are the only late Cambrian fossils known in Antarctica and the youngest yet reported from the pre-Devonian basement.Seventeen taxa of trilobites (including representatives of Pseudagnostus, Stigmatoa, Pedinocephalus, Prochuangia, and Proceratopyge), four of molluscs (Contitheca webersi, sp. nov., Hyolithes, Pelagiella, Scaevogyra), and three of brachiopods (Schizambon reticulatus, sp. nov., Billingsella, Prototreta) are described; they represent a single fauna of late Idamean (Erixanium sentum Zone; late Dresbachian, late Tuorian) age.The fauna bears affinity with faunas of Australia, China, and Kazakhstan, in agreement with affinities indicated by previously described early and middle Cambrian trilobite faunas of Antarctica.
