The lectotype of Baculites asperoanceps LASSWITZ, 1904 (Cretaceous ammonite), with a discussion on the affinities of the species

Abstract

The lectotype of Baculites asperoanceps LASSWITZ, 1904, was located in Wrocław (in German Breslau), Poland, the place of birth of the late Jost WIEDMANN. A cast of the lectotype is here figured photographically and the affinities of this poorly known Texan species are discussed.
