Description
The LAD (last appearance datum) of the radiolarian Kilinora spiralis (Matsuoka,1983) is found to concur
with the FAD (first appearance datum)of the ammonite Ataxioceras (Ataxioceras) kurisakense Kobayashi and
Fukada,1947 in the Todoro Section of the Kurisaka Formation,Southen Kurosegawa Terrane (Sakashu Belt),
Shikoku,SW Japan. Providing a clue to the still pending chronological discrepancy between European and North
American radiolarian zones,the constraint by ammonite age prolongs the range of the Kilinora spiralis Zone,a
remarkable Upper Jurassic radiolarian zone in Japan -NW Pacific region,into the Lower Kimmeridgian.
