Our team of explorers are preparing for our next adventure Mountains National Park of the Jaws, 126 kilometers from the city of San Luis. The landscape is red and rough, with extansas terraces and canyons. Joining us UNSL scientists who devoted their years of geological and paleontological research in the whole area to unravel the secrets of the jaws when it formed about 120 million years.
During the Cretaceous period of the Mesozoic era, the movement of tectonic plates glowing center of the earth fault occurred which resulted in a great subsidence. This depression formed a basin surrounded by mountains which is equivalent to the area now occupied by the National Park of the Jaws. But the current desert we see today at that time was a real garden full of rivers and lakes with extensive vegetation that encouraged the development of animal life. There lived a varied fauna among which there were several species of dinosaurs, frogs and pterosaurios.Como result of sediments carried by wind, rivers and rain, this basin was covering while the place became a real cemetery prehistoric come to light much later time. Many mountain fronts were falling on the basin covering a depth of 1500 meters. In 20 million years ago the basin was covered and converted into a plain. (By Oscar Angel Flores)
