CEMETERY fossil dates back some 120 million years
not the Peruvian Andes only been the cradle of great pre-Inca cultures, but also a large cemetery of the remains of dinosaurs and similar species that inhabited more than 4,600 meters above sea level about 120 million years.
A recent discovery of fossilized footprints shows that at least 12 species of these reptiles lived in what is today our mountains.
Such species would bipedal carnivores (theropods) of various sizes, from giant to small and herbivores semibípedos (ornithopods).
He was buried in what is now the department of Ancash and were found when performing construction work on the road that links the camp Yanacancha, Antamina mining company, with crossing Conococha at kilometer 80 of the track.
The Department of Environment of the company to carefully explore the area and found footprints in other places as well as large quantities of bones.
Among them, fossils of other animals of the Jurassic era, such as marine reptiles known as sauropterigios, of which there are entire skeletons, reptiles ichthyosaurs type (fish-shaped) and extinct crocodiles branches, as well as pterosaurs (flying reptiles ) and turtles. Also, ancient remains of fish and invertebrates impressive amounts of well preserved, refers Antamina.
According to the company, the latter findings imply a new altitude record because the fossils are found at 5,000 meters above sea level.
ORIGIN. The explanation for this presence would be in the early Cretaceous period, 120 million years ago, herds of these animals have crossed a muddy beach on the shores of a sea now disappeared, leaving the mark of his footsteps, which were quickly dried and hardened by the tropical sun.
Then, it is estimated that these footprints were covered by more sand and mud, which were preserved through geological time pitiless, until the machines were again exposed, this time the cold air of the jalcas.
