Abstract

This is a description of an Eocene Antarctic mammalian assemblage and illustrates the faunal connection that existed between Antarctic and South America, since all of these ancient Eocene Antarctic mammals had living relatives in South America. The community existed during the Early-Middle to Late Eocene when the earth was very warm, the warmest of the entire Cenozoic. Since marsupials dispersed from South America to Australia in the Early Paleocene, it is obvious that Antarctica was covered by forest until the arrival of plunging global temperatures at the end of the Eocene and Early Oligocene. Many plants that have been identified from the Antarctic Peninsula are commonly seen on the southern tip of South America even today.
