A dredge haul from a transverse fracture zone in the equatorial Atlantic Ocean yielded sediment of the Paleocene and the early Eocene ages. This sediment is the oldest thus far recorded from the Atlantic outside of the continental margins. Its occurrence is consistent with the view that transverse fracture zones are faults along which sea-floor spreading has taken place.
