The radiolarian fauna found at three sites drilled on the New Jersey continental slope range in age from late Oligocene to middle Miocene. The fauna is never abundant and is only poorly to moderately well preserved. Detailed range charts as well as a listing of stratigraphically significant radiolarian events (morphotypic first and last occurrences) are given for the three sites. Absolute ages, determined from strontium isotope analyses of mixed foraminifer species, combined with the stratigraphic ranges of the fauna provide new data concerning the age of radiolarian events in this part of the world ocean. Most of the calculated age ranges are synchronous with those derived in other areas, but three events show significant diachrony. One new taxon is described and illustrated but not named.
