A paleomagnetic investigation of the Late Cretaceous sediments of the Maud Rise, Antarctica, recovered in Holes 689B and 690C provides a fairly complete magnetostratigraphic record ranging from Chron C33N through Chron C29R. The Cretaceous/Tertiary boundary is shown to occur in Chron C29R at Site 690.
