Rudolftruempyiceras Guex & Bylund 2010

The name Boreoceras Dagys & Ermakova (1988), has been replaced with Rudolftruempyiceras Guex & Bylund 2010, Family Columbitidae, see Guex, J., Hungerbuhler, A., Jenks, J., O’Dogherty, L., Atudorei, V., Taylor, D., Bucher, H., Bartolini, A., 2010, Spathian (Lower Triassic) Ammonoids from Western USA (Idaho, California, Utah and Nevada), Memoire de Geologie (Lausanne), No. 49, on page 29. The name Boreoceras is used for an Ordovician Endocerid Nautiloid by Miller & Youngquist (1947). The ammonoids in this old post and this update, will probably be referred to Xenoceltites and not the new genus.
