Argentine Antarctica the first on the continent. On 18 December 2012, the Foreign & Commonwealth Office of the United Kingdom announced that the southern part of British Antarctic Territory (and Argentine Antarctica) has been named "Queen Elizabeth Land" in honour of Queen Elizabeth II. Argentina, which lays claim to part of the area, criticised the naming. In 2013 the Argentine Defense Ministry announced that Petrel Base will become a permanent base by 2015. The base will have an airport and logistics for transfer of passengers and cargo. The geographic structure of the Argentine Antarctica continues some features of the Patagonia, located to
Antarctica cooling of Antarctica occurred stepwise, as the continental spread changed the oceanic currents from longitudinal equator-to-pole temperature-equalising currents to latitudinal currents that preserved and accentuated latitude temperature differences. Africa separated from Antarctica in the Jurassic, around 160 Ma, followed by the Indian subcontinent in the early Cretaceous (about 125 Ma). By the end of the Cretaceous, about 66 Ma, Antarctica (then connected to Australia) still had a subtropical climate and flora, complete with a marsupial fauna. In the Eocene epoch, about 40 Ma Australia-New Guinea separated from Antarctica, so that latitudinal currents could isolate Antarctica from Australia, and the first
