A remarkable discovery in the Italian Alps has unveiled a 280-million-year-old world preserved in stunning detail, shedding light on life during the Permian period—a time long before dinosaurs walked the Earth.
Claudia Steffensen, a hiker exploring the Valtellina Orobie Mountains Park in Lombardy, stumbled upon the ancient traces entirely by chance in 2023. What began as a curious glance at unusual patterns on a light gray rock evolved into an extraordinary find that has captivated paleontologists and opened a window into Earth’s distant past.
Steffensen’s sharp eye caught what she initially thought were designs etched into the rock. Upon closer inspection, she realized these “designs” were fossilized footprints. Recognizing the significance of her find, she sent photographs to experts, who quickly confirmed that the tracks were the handiwork—so to speak—of a prehistoric reptile. Further investigations of the site revealed hundreds of similar footprints left by at least five species of ancient reptiles, amphibians, and even insects.
The fossils were embedded in fine-grained sandstone, their preservation aided by the watery environment in which they were originally formed. As paleontologist Lorenzo Marchetti of the Museum of Natural History in Berlin explained, the tracks retained “impressive detail,” down to claw marks, skin textures, and even the imprints of tiny fingernails. These creatures likely roamed the margins of rivers and lakes that periodically dried up, leaving soft mud surfaces that hardened under the summer sun. Subsequent layers of sediment sealed and preserved the footprints for eons.

In addition to animal tracks, researchers found imprints of ancient plants, including seeds, leaves, and stems. Even the delicate markings of raindrops and wave patterns were captured in the rock, painting a vivid picture of a thriving ecosystem along the shores of a prehistoric lake. According to co-researcher Ausonio Ronchi of the University of Pavia, these conditions allowed for unparalleled fossil preservation, providing a glimpse into an ancient world that had remained hidden beneath layers of sediment and rock.
What makes this find even more remarkable is its altitude. These fossils were discovered at heights of up to 10,000 feet, an unusual location for such well-preserved relics. Geologists believe landslides and other natural processes exposed the fossils, bringing to light a long-forgotten chapter of Earth’s history.
The Permian period, lasting from approximately 299 to 252 million years ago, was a time of dramatic change. It was marked by the evolution of diverse reptilian species and the emergence of complex ecosystems. However, it ended with the largest mass extinction event in Earth’s history, which wiped out nearly 90% of all species. These fossils, preserved in breathtaking detail, offer scientists a chance to study the intricacies of life before this catastrophic event.
Steffensen’s serendipitous find highlights the importance of exploration and curiosity. Her discovery has not only provided a snapshot of a lost world but has also sparked renewed interest in the untold stories hidden in Earth’s geological record. These fossils, untouched for millions of years, stand as a testament to nature’s resilience and its ability to surprise us when we least expect it.
