Antarctica

Dinosaur fossils have been found on all seven continents, including Antarctica. The Antarctic continent, once part of the supercontinent Gondwana, was warmer during the Mesozoic era and supported a variety of dinosaur species. Fossils of Cryolophosaurus ('frozen crested lizard'), a large theropod, were discovered there in 1991. During the Triassic period, all continents were joined as Pangaea, allowing dinosaurs to spread across the entire land mass.

The Argentine Antarctica claim, extending from 25°W to 74°W longitude, overlaps with claims by the United Kingdom and Chile. This territorial assertion is based on historical presence and geographical proximity, although international treaties suspend sovereignty claims.

These resilient birds huddle together in massive colonies, rotating positions to share warmth and reduce individual exposure to the brutal Antarctic winds. Their dense, multi-layered feathers and thick blubber provide exceptional insulation against the extreme cold.

This extreme low was measured at Vostok Station in East Antarctica on July 21, 1983. The station's location on a high plateau, far from moderating ocean influences, combined with long winter nights and clear skies, creates optimal conditions for such record-breaking frigid temperatures.

A desert is defined by its low precipitation, not necessarily high temperatures. Antarctica receives less than 200 millimeters (7.9 inches) of precipitation annually, almost entirely as snow, making it the coldest and largest desert.
