Steffensen’s discovery provides a rare glimpse into a prehistoric world, raising questions about the life forms that once thrived in these mountainous regions.
Unearthing the Past
The urgency to document ancient finds has escalated due to climate change. Alpine glaciers are retreating at unprecedented rates, revealing geological layers that have remained hidden for thousands of years. Between 2022 and 2025, Switzerland experienced a significant loss of nearly 6% of its glacier ice.
The World Meteorological Organization reported a staggering 450 billion tons of glacier melt globally in 2024. As climate-driven ice retreat serves as an archaeological time machine, the melting ice reveals ancient ecosystems, allowing scientists to study remnants of a world lost in time.
Understanding the Permian Period
Before the reign of dinosaurs, the Earth was a vastly different place. The Permian period, which occurred between 299 and 251 million years ago, was a time when diverse reptiles and amphibians flourished across the supercontinent Pangaea. Surrounded by the ancient ocean Panthalassa, this unified landmass supported a wide variety of life.
However, fossil records from this period are sparse and fragmented, making each discovery invaluable for paleontologists. The tracks discovered by Steffensen provide a rare opportunity to gain a deeper understanding of life in this long-gone era, shedding light on the evolution of prehistoric creatures.
A Race Against Time
As glaciers retreat, the window for uncovering fossilized evidence is closing rapidly. Weathering and erosion commence as soon as the ice recedes, posing a significant threat to exposed geological formations. Scientists are racing to explore these newly revealed sites, striving to document their findings before environmental degradation erases the evidence forever.
The paradox of climate change becomes evident: while the warming climate reveals ancient treasures, it simultaneously threatens existing ecosystems. Paleontologists urge immediate action to study these Vital fossils from the Permian period, as they risk being lost to time yet again.
280-Million-Year-Old Tracks Revealed
Steffensen’s discovery of fossilized tracks proved to be groundbreaking. Scientific analysis dated the tracks to approximately 280 million years ago, during the Middle Permian period, well before the appearance of dinosaurs. Located in the Orobie Valtellinesi mountains of Lombardy, the site was deemed one of the “most abundant and well-preserved Permian sites” that paleontologist Lorenzo Marchetti had ever encountered.
Hundreds of tracks from at least five distinct species have been documented, including creatures measuring 2-3 meters long. This significant find not only enriches our understanding of the Permian ecosystem but also highlights the area’s geological importance.
The Geological Context
The discovery site is located within the Valtellina Orobica Alps Regional Park, a protected area in the Sondrio Province, renowned for its stunning mountainous terrain. This park spans over 44,000 hectares and features peaks exceeding 3,000 meters.
Its unique geology consists of gneiss, mica, phyllite, sandstone, dolomite, and limestone types of rock that are conducive to preserving ancient impressions when sediments harden. Interestingly, the high-altitude location and isolation have safeguarded these fossils for approximately 280 million years, allowing them to be discovered only now as climate change reveals hidden treasures.
Clarity Amid Chaos
Claudia Steffensen’s momentous discovery occurred during a summer hike in 2023. Seeking refuge from the heat, she stumbled upon a rock with unusual markings. Intrigued, she examined the stone closely and revealed circular designs interspersed with wavy patterns distinctly resembling footprints.
Capturing the site’s essence, she photographed the evidence and shared her findings with her friend, Elio Della Ferrera, a nature photographer.
