Imagine strolling through a picturesque Italian mountain range, fresh air filling your lungs and stunning scenery washing over you. Now, picture stumbling upon a hidden window into Earth’s distant past, a glimpse of life from a time before dinosaurs even roamed the planet. That’s exactly what happened to hiker Claudia Steffensen in 2023 while exploring the majestic Italian Alps.

Steffensen, on a regular hike with her husband in the Valtellina Orobie Mountains Park in Lombardy in 2023 spotted something unusual. What appeared to be an ordinary rock nestled amongst the trail held a secret. Upon closer inspection, she noticed strange, circular designs with wavy lines etched across its surface. Intrigued, she realized these weren’t just random markings – they were animal footprints!

Unsure of the significance of her discovery, Steffensen captured photos of the peculiar rock. These pictures would soon unlock a portal to a bygone era.  She shared the images with her friend, a nature photographer, who, in turn, forwarded them to paleontologists at the Natural History Museum of Milan. The moment the experts saw the intricate details; their hearts skipped a beat.

The team at the museum quickly identified the footprints as belonging to creatures that roamed the Earth a staggering 280 million years ago! This period, known as the Permian, occurred even before dinosaurs roamed the earth. It was a crucial time in the history of life on our planet.

A Lost Ecosystem Emerges

The discovery of the first rock, dubbed “Rock Zero,” was just the beginning. Further exploration in the area revealed a treasure trove of fossilized tracks on slabs of sandstone. These weren’t just isolated prints – the site held the remains of an entire prehistoric ecosystem, preserved in remarkable detail. Further investigation revealed hundreds of other fossilised footprints t made by over five species of ancient reptiles, amphibians and insects.

The fossilized evidence wasn’t limited to footprints. Scientists unearthed impressions of ancient plants, including seeds and stems, offering insight into the flora that thrived in this lost world. The site even yielded raindrop imprints, a testament to the weather patterns of the Permian period.

Ironically, the retreat of glaciers in the Alps due to rising global temperatures played a role in exposing this ancient world. While the discovery is a scientific triumph, it serves as a stark reminder of the impact humans are having on the planet.
