The Cenozoic and perhaps latest Mesozoic history of the Ross Sector was dominated by a major tectonic episode during which the Transantarctic Mountains and Ross embayment developed. A Transantarctic Passage between East and West Antarctica may have provided for a Pacific Atlantic marine connection early in the history of the Victoria Orogeny. Both terrestrial and marine environments existed under early temperate and subsequent glacial climatic conditions.
