Book excerpt: The excellent preservation of radiolarians in formations on the Queen Charlotte Islands, and the precision to which they can be dated from closely associated ammonites and other fossils, makes them especially suitable for constructing integrated biochronological zonations and detailed taxonomic studies. The purpose of this study is to develop a detailed radiolarian zonation for the Lower Jurassic, to integrate new radiolarian zones with ammonite assemblages for that period, to document the range and distribution of the Queen Charlotte Islands radiolarians as completely as possible, and to describe new taxa. The first part reviews the lithostratigraphy of the formations studied, the independent fossil dating methods used, the diversity and composition of the radiolarian faunas observed, the radiolarian biochrolology and chronostratigraphy, and paleobiogeography of the area's radiolarians and ammonites. Part 2 is a systematic palaeontology describing radiolarian species by suborder, family, and genus.
