Valle de la Luna – the Valley of the Moon – is also called the Ischigualasto Provincial Park of Argentina, and there you can find fossils of the world’s oldest dinosaurs. They arose during the Late Triassic, as the planet healed from a mass extinction due to volcanic eruptions so severe that 90% of life on earth died out. The sedimentary rocks exposed here are perfect for retaining traces of past life forms in fossils and footprints.
