'Big Pig Dig': In 1994, two hikers discovered a 34-million-year old site in South Dakota's Badlands with fossils of prehistoric rhinos, small horses and huge carnivorous pigs

In 1994, two hikers stumbled upon enormous bones in South Dakota's Badlands, igniting a wave of scientific exploration that lasted years. This serendipitous discovery led to the unearthing of over 19,000 fossils from a site believed to be an ancient watering hole, where animals converged during a severe drought around 34 million years ago. The Big Pig Dig provides valuable insights into prehistoric ecosystems and shifts in climate.
