Die verlorene Welt der Antarktis
Summary
This episode explores the prehistoric Antarctic ecosystem, revealing that a temperate rainforest with regular lightning-induced fires existed near the South Pole 90 million years ago. Researchers analyzed sediment cores from the Amundsen Sea to reconstruct this environment, identifying fossilized roots, pollen, and charcoal that indicate the forest eventually evolved into a peat bog, forming some of the oldest known coal in high southern latitudes. The narrative also highlights a 2026 discovery confirming that a vertebra found in 1985 on James Ross Island belongs to a titanosaur, marking th…
