An extraordinary scientific discovery has emerged in Italy’s Stelvio National Park, in the Lombardy region, where researchers have identified thousands of dinosaur footprints dating back approximately 210 million years. The tracks stretch for several kilometers across the Fraele Valley near Valdidentro, between Livigno and Bormio, and are believed to have been left by large herbivorous dinosaurs that moved in herds. Experts describe the find as the most significant dinosaur track discovery in Italy in decades and one of the most important ever documented in the Alpine region.
The footprints are preserved on nearly vertical dolomite rock walls, a striking reminder of the dramatic geological transformations the area has undergone over millions of years. Some impressions retain remarkable detail, including clearly defined toes and claws, providing scientists with rare insights into the anatomy, body weight, and movement patterns of these prehistoric animals. According to paleontologist Cristiano Dal Sasso of the Milan Natural History Museum, the site represents “a true dinosaur valley,” calling it the largest dinosaur track site in the Alps and one of the richest of its kind worldwide.
When these footprints were formed, the region bore little resemblance to the Alpine landscape seen today. The dinosaurs walked along the shores of the ancient Tethys Ocean, in an environment more akin to modern tropical coastlines. Analysis of the trackways suggests coordinated movement, supporting the theory that these animals traveled in groups. Some patterns even indicate complex behaviors, such as synchronized motion or circular formations, offering valuable clues about the social structure and interactions of early dinosaurs.
The discovery was made by chance on September 14, when nature photographer Elio Della Ferrera was exploring the area to document wildlife. He noticed unusually large impressions, some measuring up to 40 centimeters, embedded in the rock. After alerting specialists, the markings were confirmed as dinosaur footprints, marking the first such discovery ever recorded in Lombardy.
Since then, scientific teams have begun extensive documentation and analysis to preserve the site and unlock its full research potential. Beyond its regional significance, the find provides crucial information about the early evolution of dinosaurs during the Triassic period, their behavior, and the ancient environments they inhabited. For science, it opens a rare window into a distant chapter of Earth’s history; for humanity, it stands as a powerful reminder of the deep natural past etched into the planet’s surface, waiting patiently to be revealed.
