Outline of Final Research Achievements

Molluscan shell microstructures were observed and compared in detail across various taxonomic groups. Phylogenetic correspondence is evaluated between molecular phylogenetic trees and taxonomic distribution of microstructures. Each microstructure is characterized by a combination of electron microscopy, distinction of aragonite and calcite, and crystallographic analysis.
