Résumé du livre
Four new genera of osteolepiforms and a new rhizodontiform genus are described from the Middle-Late Devonian Aztec Siltstone (Beacon Supergroup) of Antarctica. Other indeterminate osteolepid, eusthenopterid and rhizidontid remains, and a single indeterminate porolepiform scale, are described from the same formation.
