Triassic Amphibian from Antarctica
A fossil bone fragment—the first record of tetrapod life from Antarctica—was found near Graphite Peak in the upper Beardmore Glacier area (85°3.3′S; 172°19′E). The fragment was embedded in a pebbly quartzose sandstone, probably of fluvial origin, in the lower part of the Triassic Fremouw Formation (...
