Ancient 40-Million-Year-Old River Found Beneath Antarctic Ice

Geologists from the Alfred Wegener Institute have discovered evidence of a 40-million-year-old river system beneath the Antarctic ice by studying sediment samples from the Amundsen Sea. This finding suggests that Antarctica once had a temperate climate with lush forests and extensive river networks, significantly different from its current icy landscape. The sediments indicate that the river system transported erosion debris from the Transantarctic Mountains, highlighting the continent's dramatic climatic and geological changes over millions of years.
