Taxonomy

Bogoslovskya was named by Zhuravleva (1978)[1] which at that time included 5 species from the Devonian of the Ural Mountains. Since then three more species have been described from the Carboniferous and Permian of Japan. Bogoslovskya was originally assigned to the subfamily Michelinoceratinae within the Orthocerida, wherein it was listed by Sepkoski (2002)[2] and reassigned to the Palliocerida by Zhuravleva (2005) and placed in the newly established Bogoslovskyidae.

Morphology

Bogoslovskya has an orthoconic shell with an empty eccentric siphuncle of which there are only very thin and narrow septal necks that are thickened at the edge but with no evidence of connecting rings. Species from the Devonian of the Urals have smooth shells; later forms from Japan possess transverse ornamentation in the form of lirae or thin riblets.
