Fig. 55 in Scaphites Of The ''Nodosus Group'' From The Upper Cretaceous (Campanian) Of The Western Interior Of North America

Fig. 55. Hoploscaphites nodosus (Owen, 1852), macroconchs, transitional to H. brevis. A–C. USNM 536233, USGS Mesozoic loc. 23072, Pierre Shale, near Sage Creek, Pennington County, South Dakota. A chunk of shell is missing from the adapical part of the body chamber. A. Apertural; B. ventral; C. left lateral. D–F. AMNH 58512, more slender and finely ribbed than holotype, locality unknown. D. Ventral hook; E. apertural; F. left lateral. These specimens are assigned to H. nodosus rather than H. brevis because the body chamber is elongate and the ventrolateral tubercles persist to the aperture. Specimens are illustrated natural size.

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).
