They’ve just unlocked 1.2 million years of Earth’s secrets in Antarctica
This article covers the Beyond EPICA project’s announcement of a 1.2-million-year-old Antarctic ice core, which helps place Antarctica’s deep history in context even though it is not a lost-civilization piece. It is useful as a recent discussion of ancient Antarctic climate and ice, showing how researchers are recovering evidence from deep time beneath the ice sheet.

55 million-year-old penguin fossils reveal hidden chemical clues about Antarctica before the continent became frozen
This article looks at 55-million-year-old penguin fossils from Seymour Island and the chemical clues they preserve about Antarctica before it froze. It uses the fossils as a window into Antarctic weathering and climate change during the Eocene, helping reconstruct the continent’s transition from a warmer world to the frozen landscape seen today.
Early world maps
This entry summarizes the Piri Reis map and the long-running controversy over whether it depicts Antarctica or simply extends South America southward. It also notes the mainstream explanation that the southern coastline may have been bent to fit the parchment rather than representing pre-ice-age Antarctica.
Mountain Formation Explains the Antarctic Ice Sheet Mystery
This piece focuses on a geological explanation for how Antarctica’s ice sheet formed, arguing that mountain uplift and tectonic processes helped trigger East Antarctica’s long-term glaciation. It is useful background for readers interested in what Antarctica was like before and during the transition into its frozen state.
