Palaeontologists in southern Argentina have uncovered an enormous network of fossils dating back to the Jurassic period, enabling them to reconstruct an entire ecosystem that has remained “frozen” in time for around 140 to 160 million years. The discovery occurred in the locality of La Bajada, in a region of southeast Patagonia called the Deseado Massif, where recent soil erosion across an area spanning some 60,000 square kilometers (23,000 square miles) has exposed the fossils.
