A revision of the Ordovician cephalopod Bactrites sandbergeri Barrande: systematic position and palaeobiogeography of Bactroceras

Popis výsledku v původním jazyce

Over one hundred specimens assigned to three species of the cephalopod genus Bactroceras (= Eobactrites) from the Ordovician of the Prague Basin (Czech Republic) have been studied in detail. Preservation of the material allows study of external featuresincluding the embryonic shell, as well as some internal structures of the shell. Muscle scars, described for the first time in Bactroceras, show a simple, unpaired and low, dorsally-situated lobe (""orthoceridan"" type of muscle scars). The type speciesof the genus, Bactroceras avus, is synonymized with Bactroceras sandbergeri based on strong similarities in the outer morphology of the shell and the position and internal structure of the siphuncle. A new species of Bactroceras from Bolivia is erected:Bactroceras boliviensis. Orthoceras interpolatum Barrande, 1870, from the Upper Ordovician of Bohemia, is assigned to Bactroceras; it is one of the stratigraphically youngest species of the genus. The assignment of Orthoceras gossei Ether
