- Africa: Oxygen Atoms in 15-Million-Year-Old Giant Eggshells Reveal How Plants Reacted to a Hotter Earth - Study
A study analyzed oxygen atoms in 15-million-year-old giant eggshells to reveal how plants responded to a hotter Earth during the Miocene Epoch. Scientists are particularly interested in this intermediate geological period between the age of dinosaurs and more recent eras like the Ice Age.
