Rich radiolarian faunas were obtained continuously from Middle Jurassic to Lower Cretaceous radiolarite sequences at Sites 800 and 801, drilled during Ocean Drilling Program Leg 129 in the western Pacific. Occurrences of 90 taxa are presented in tables for these sites. Seven radiolarian zones, Dibolachras tytthopora, Cecrops septemporatus, Pseudodictyomitra carpatica, Pseudodictyomitra primitiva, Cinguloturris carpatica, Stylocapsa spiralis, and Tricolocapsa conexa in descending order, were recognized in this interval. The radiolarite sequences of Sites 800 and 801 encompass approximately the Berriasian to Hauterivian (or to Barremian) and the Bathonian/Callovian to Valanginian ages, respectively. At Site 801, a hiatus of early Oxfordian was identified.
