The Valley of the Dinosaurs is an area in the sedimentary basin of the Peixe River that holds over 50 types of ancient animal tracks, including those of stegosaurids, allosauroids and iguanodonts.

[1] The valley covers an area of about 700 square kilometres (270 sq mi) that includes the city of Sousa, Paraíba, and ten other municipalities.

[7] The Área de Relevante Interesse Ecológico Vale dos Dinossauros was established on 18 December 1984 and is administered by the Chico Mendes Institute for Biodiversity Conservation (ICMBio).

The replica of Tyrannosaurus Rex had been destroyed, access roads were covered by scrub, there were hundreds of cobblestones around the entrance, piles of sand and other problems.

[10] In February 2016 the Federal Public Ministry (MPF) in Sousa recommended that Paraíba Office of Environment Administration (SUDEMA) prepare the management plan for the natural monument within 90 days defining steps to ensure the integrity and protection of natural resources of the site, and steps taken to integrate it into the social and economic life of the surrounding communities.

The MPF also recommended that SUDEMA give a detailed report within 30 days on the work carried out by the Sousa Prefecture in the Valley of Dinosaurs, which should be limited to protecting the integrity of the unit.
