Abstract
The history of changing views on the taxonomy and classification of nautilids of the family Liroceratidae Miller et Youngquist, 1949 is briefly discussed. The diagnosis of the genus Shikhanonautilus Leonova et Shchedukhin is emended based on a study of new material from the Asselian-Sakmarian deposits in the Shakhtau Quarry. A new species S. compressus is described and a more detailed characterization of the type species S. siphonoventralis Leonova et Shchedukhin is given.
