| Outline of Final Research Achievements |
Cretaceous sessile organisms were commonly observed on molluscan shells. It was revealed that the Late Cretaceous nostoceratid ammonoids, Pravitoceras and Didymoceras, are frequently encrusted by anomiid bivalves, and information about ecology of these heteromorph ammonoids was obtained by observation of modes of occurrence of them. The detailed burial process of a shell of the Late Cretaceous large ammonoid was also reconstructed based on the attachment pattern of gryphaeid bivalves.
