Feature Facts

  • An extinct Ice Age capybara, species undetermined, has been discovered in Southern California from 200,000 year-old lake sediments. Several other water-loving animals including tapir, pond turtle, frog, and water birds were discovered in nearby rocks of the same age. Together these fossils indicate a wet habitat there at that time.
