A woman hiking through the Italian Alps made a startling discovery when she happened upon the remains of an ancient ecosystem. Claudia Steffensen was hiking with her husband in the Valtellina Orobie Mountains National Park, near the Swiss-Italian border when she noticed large circular patterns on the rocks. Upon closer inspection, the patterns, which featured wavy lines, appeared to be footprints.
After much speculation with friends, an image of Claudia’s discovery made its way to experts at the Museum of Natural History in Milan, who investigated further. Now, scientists have confirmed that the footprints belonged to prehistoric reptiles, dating back to the Permian period, about 280 million years ago. Alongside the footprints, further investigation uncovered the fossilized remains of an entire prehistoric ecosystem, including traces of reptiles, amphibians, and insects alongside fossilized plants and seeds.
The ground-breaking discovery offers scientists a rare window into a mysterious period of Earth’s history, before the existence of humans and dinosaurs alike. “At that time, dinosaurs did not yet exist, but the animals responsible for the largest footprints found here must still have been of a considerable size,” said Cristiano Dal Sasso, vertebrate paleontologist at the Natural History Museum of Milan. Although a handful of similar discoveries have been made in recent years, the detail and significance of this one has seen it dubbed ‘Rock Zero’.
