Dinosaur Valley Natural Monument, Natural monument in Sousa, Brazil

Vale dos Dinossauros is a natural monument in Sousa featuring numerous fossilized footprints embedded in rock layers from millions of years ago. The tracks are scattered across the site in different sizes and patterns, each one a window into how these ancient creatures walked and moved through this landscape.

Millions of years ago, different dinosaur species roamed this region and left their footprints in soft mud. Over time, sediment covered these impressions and hardened into rock, creating a natural record of their presence that has survived to today.

The natural monument functions as an educational center where researchers conduct paleontological studies and document the prehistoric heritage of northeastern Brazil.

The site is open on most days and visitors can walk on marked pathways to see the footprints up close. Wear comfortable shoes and bring sun protection, as you will be walking outdoors for an extended period.

The Passagem das Pedras site holds a trackway running 43 metres in a straight line, the longest known dinosaur trail in the world. The same riverbed yielded the first evidence of Brazilian dinosaurs, found by farmer Anísio Fausto Silva in the late 19th century. In 2016 a local man, Luiz Carlos Gomes, showed palaeontologist Aline Ghilardi a bone that became Sousatitan.
