After Scott & Cobban (1965). different arrangement from that of older baculites'. The remaining, later Maastrichtian species of the Western Interior, B. baculus (an immigrant from the Gulf Coast), and its descendants, B. grandis and B. clinolobatus have, in contrast, a simple suture (Fig. 29E), comparable to that of the B. ohtusus- B. perplexus group. As mentioned above, Pseudobaculites natosini from the Upper Campanian and Lower Maastrichtian, has a complex suture characteristic of the genus. Details of the Baculites succession of the Indo-Pacific and European regions are less precisely known than those of the US Western Interior. Matsumoto.
