The archaeological site Lajedo de Soledade is one of the most important in Brazil and the largest limestone exposure of Bacia Potiguar, located on the Apodi tableland in the western region of the Rio Grande do Norte and formed 90 million years ago when shallow sea covered the region. The appearance of the limestone structure is a consequence of the retreat of the sea and the formation of small canyons, crevices and caves was the result of erosions caused by rains and currents that sculpted the limestone.
Due to those sets of structures, enormous animals of the Pleistocene megafauna of the ice age and, m ore recently, the prehistoric man, inhabited that site. What these conjectures prove are the great amount of vestiges found of these occupations, such as: mastodon bones, armadillo, saber-tooth tigers and giant sloth or records of cave paintings on the floors, walls and ceilings of the rocky shelters that would have been made by nomadic men who lived there.
The site is divided into three areas, the first one is called Vulture, because it has dark rock formations, pointed and several caves, that resemble this bird. The second is known with Macaw, because it has cave paintings made hundreds of years ago, many similar to macaws. The third one is called the Water's Eye, because in this area you can find many waterhole.
The scientific, cultural and historical value of this archaeological site is enormous. To know this place is to participate in a fascinating adventure through the interior of the brazilian northeast, discovering the origins of a people and the marks left as clues of a huge enigma.
