英文摘要
The consequences of our research include four main topics. (1) Apomorphic or plesiomorphic characters were determined in "living fossil" Nautilus pompilius by comparing characters states of Nautilus with those of other cephalopods and molluscs. (2) Based on ontogenetic data on Nautilus embryo, a new hypothesis was proposed concerning the origin of cephalopod body plan from a primitive conchiferan stage. (3) High diversity of modern-type coleoidean cephalopods in the Cretaceous was revealed by detailed examinations of fossil jaws. (4) The cause of the end-Cretaceous extinction in ammonoids was inferred to be a decline of primary producers in the ocean.
