In a remarkable twist of fate, the effects of modern climate change have unveiled a window into the distant past. A hiker traversing the rugged terrain of the Italian Alps stumbled upon the first trace of what experts believe to be an entire prehistoric ecosystem, dating back an astonishing 280 million years.
The serendipitous discovery occurred in the picturesque Valtellina Orobie mountain range in Lombardy, nestled close to the Swiss border. As the hiker carefully navigated a rocky trail in the Ambria valley, a peculiar sight caught her eye—a light grey rock adorned with intriguing circular designs and wavy lines.
A Chance Encounter Leads to a Groundbreaking Find
The hiker, Claudia Steffensen from the nearby village of Lovero, had ventured into the mountains with her husband to escape the sweltering heat of the summer. Little did she know that her keen observation skills would lead to a discovery of immense scientific significance.
“I put my foot on a rock, which struck me as odd as it seemed more like a slab of cement,” Steffensen recounted. “I then noticed these strange circular designs with wavy lines. I took a closer look and realised they were footprints.”

Intrigued by her find, Steffensen documented the unusual patterns with a photograph and shared it with Elio Della Ferrera, a friend and photographer specializing in the natural world. Della Ferrera, sensing the potential significance of the discovery, promptly forwarded the image to Cristiano Dal Sasso, a paleontologist at the Museum of Natural History in Milan.
Experts Uncover a Treasure Trove of Prehistoric Life
Upon examination, the experts determined that the footprints, found at an altitude of 1,700 meters, belonged to a prehistoric reptile that roamed the Earth long before the age of dinosaurs. Energized by this revelation, a team of paleontologists and ichnologists (trace fossil specialists) embarked on a meticulous survey of the Valtellina Orobie nature park, spanning altitudes of nearly 3,000 meters.
Their efforts yielded a treasure trove of ancient life. Subsequent visits to the site since the summer of 2023 have revealed hundreds of fossilized footprints belonging to reptiles, amphibians, and insects, often still aligned to form discernible tracks. The traces are believed to originate from at least five distinct animal species.
“Dinosaurs did not yet exist, but the authors of the largest footprints must still have been of a considerable size – up to 2-3 metres long,” noted Dal Sasso.

Unveiling the Secrets of a Lost World
The exceptional preservation of the footprints has allowed researchers to glean impressive details about the creatures that left them behind. According to Lorenzo Marchetti, an ichnologist at the Museum of Natural History in Berlin, the traces reveal “the imprints of fingernails and the belly skin of some animals.”
Beyond the animal traces, the prehistoric ecosystem has also yielded fossilized fragments of plants, seeds, and even the delicate imprints of ancient raindrops. This comprehensive snapshot of life from the Permian period, which ended with the most severe mass extinction event in Earth’s history, offers an unparalleled opportunity to study a vanished world.
Climate Change: A Double-Edged Sword
Ironically, it is the effects of contemporary climate change that have made this groundbreaking discovery possible. The melting of snow and ice in the Italian Alps has exposed traces of other prehistoric animals in recent years, including the footprints of a crocodile-like reptile found at an altitude of 2,200 meters in the province of Cuneo.
“The discovery in the Ambria valley is also an effect of climate change,” noted Doriano Codega, president of the Valtellina Orobie nature park. “The exceptional thing was the altitude – these relics were found at very high levels and were very well preserved.”

While the revelation of this prehistoric ecosystem is a boon for the scientific community, it serves as a stark reminder of the profound impact that climate change is having on our planet. As glaciers recede and permafrost thaws, long-buried secrets of the past are coming to light, even as the future of our own ecosystem hangs in the balance.
Preserving the Past, Safeguarding the Future
The site of Steffensen’s discovery, now known as “Rock Zero,” has become the focal point of ongoing research efforts. Selected relics from the Ambria valley have been transported to Milan for display at the Museum of Natural History, offering the public a glimpse into this fascinating chapter of Earth’s history.
As scientists continue to unravel the secrets of this prehistoric ecosystem, their findings may provide valuable insights into the resilience and adaptability of life in the face of dramatic environmental changes. By understanding the past, we may be better equipped to navigate the challenges of the present and safeguard the future of our own fragile ecosystem.
In the end, the chance discovery made by a curious hiker in the Italian Alps serves as a poignant reminder of the enduring power of nature and the interconnectedness of all life, both past and present. As we grapple with the consequences of our own actions on the planet, the footprints of prehistory offer a silent testament to the indomitable spirit of life itself.
