This simple sutural pattern is retained in the Coniacian in Europe in B. incurvatus (Fig. 26B-C), in the Indo-Pacific in B. capensis (Fig. 26D-E), B. yokoyamai and B. bailyi, and in the US Western Interior in B. yokoyamai, B. mariasensis (Fig. 25D), B. sweetgrassensis and B. codyensis. In contrast, the sutures of Pseudobaculites, thus far only known from three species, P. Wyomingensis and P. nodosus (Fig. 26A) from the Upper Coniacian, and P. natosini from the Upper Campanian and Lower Maastrichtian of the US Western Interior, are extremely complex. The saddles are slender-stemmed and asymmetrically dendritic. The larger size of Pseudobaculites in the Coniacian.
