Fig. 2 in Scaphites Of The ''Nodosus Group'' From The Upper Cretaceous (Campanian) Of The Western Interior Of North America
Fig. 2. Upper Cretaceous (Campanian and Maastrichtian) ammonite biostratigraphy of the U.S. Western Interior showing the zones of Baculites compressus and B. cuneatus (Cobban et al., 2006). The absolute ages are derived from 40Ar/39Ar analyses of bentonites containing sanidines. In North America, the Campanian is divided into three parts. The Campanian/Maastrichtian boundary is currently placed in the middle of the B. eliasi Zone, based on recent work in Tercis, France, and the Vistula River Valley, Poland (Remin, 2009).
