Abstract

Several planktonic organisms, spores and pollen grains have been isolated from Tertiary and Cretaceous sediments of a 2000 m bore located at Tierra del Fuego, approximately 14 kilometers south of the San Sebastián Bay (5~)0 25' lat.

They are two new spccies of Deflandrea, two of Hystrichosphaeridium, one of Micrhystridium, Odontochitina aff. porifea Cookson, and Hystrichosphaera furcata (Ehrenberg) O. Wetzel.
