Abstract

ABSTRACT Therapsids from the base of the upper Fremouw Formation in the Beardmore Glacier region of Antarctica are described. They are part of a new fauna that also includes large capitosaurid temnospondyl amphibians. Cynognathus sp., as well as indeterminate specimens of cynognathids, a diademodontid and a kannemeyeriid occur. While the presence of Cynognathus and the kannemeyeriid suggest a late Scythian (late Early Triassic) age for this level in the Fremouw Formation, some aspects of the indeterminant taxa may indicate a slightly younger Anisian (early Middle Triassic) age.
