SCAPHITES OF THE "NODOSUS GROUP" FROM THE UPPER CRETACEOUS (CAMPANIAN) OF THE WESTERN INTERIOR OF NORTH AMERICA

SCAPHITES OF THE "NODOSUS GROUP" FROM THE UPPER CRETACEOUS (CAMPANIAN) OF THE WESTERN INTERIOR OF NORTH AMERICA

Scaphitid ammonites (scaphites) are common in the Upper Cretaceous Pierre Shale and Bearpaw Shale of the Western Interior of North America. We redescribe Hoploscaphites nodosus (Owen, 1852) and H. brevis (Meek, 1876) from the Baculites compressusB. cuneatus zones of the upper Campanian. The types of...
