Dinosaurierspuren vom Monte Buso, Dinosaur footprints site at Monte Buso, Trentino, Italy.

The Dinosaurierspuren vom Monte Buso are three three-toed negative footprints, about 30 cm each, on the ceiling of the Stol dei Campiluzzi tunnel at roughly 1980 m on the Pasubio massif in Trentino, Italy. Two prints partly overlap and belong to two theropod trackways made at different times; claw marks show at the front ends. The animals were about 2 m tall, 7 to 8 m long and 400 kg, assigned to the genus Dilophosaurus.

The tracks date from the Early Jurassic and were found in 2010 by researchers from the Trentino Natural Science Museum while examining the tunnel. The tunnel itself had been cut into the rock by the Austro-Hungarian army for military use between 1916 and 1918.

The footprints sit inside a tunnel that was dug for military purposes, giving the site an unusual double nature. Information panels on site explain in plain terms what the tracks reveal about how these animals moved and behaved.

The site is reached from the western entrance of the rock tunnel, with the footprints found roughly 130 meters inside. Bringing a torch is a good idea, as it helps pick out the finer details of the fossil marks on the ceiling.

The tracks lie on the tunnel ceiling about 130 m from the western entrance, where the rock sequence is inverted: the sediment surface the dinosaurs walked on now faces downward. The three three-toed prints, roughly 30 cm each, belong to two trackways made at different times, probably by two Dilophosaurus-like theropods about 2 m tall, 7 to 8 m long and 400 kg.
