Abstract
Moderately well preserved Permian and Early(?) Triassic radiolarian faunas from sedimentary melange cherts of the Grindstone terrane in central Oregon are nearly identical to coeval chert faunas in Japan. Although several Oregon taxa have been reported from limestone sequences in the central United States, most of the Oregon forms have only been found in cherty rocks and nearly half have not previously been reported from North America. Forty-two taxa belonging to 19 genera are systematically treated. Co-occurrences of some species in Oregon indicate that their ranges in North America may differ from those in Japan. -from Authors
