From Cipolletti it is possible entering a remote world, warm, full of colors characteristic of the ancient land. Where the rivers Limay and Neuquen embraces there is the Cretaceous Park Tourist Corridor, a corner of Patagonia with high paleontological value.
The presence of fossils of dinosaurs provides the ideal framework among the rocks that left guessing red sandstone strata and clay. The wind and water in these latitudes did a wonderful job of sculpture, carving canyons looking mole.
The Cretaceous Park covers about 40% of the territory of the southern edge of Cipolletti, considered a protected area since 1996 to preserve the heritage formed by fossil flora and fauna of cretaceous origin.
Between the possibilities of the site visitors can choose to go to the Anfiteatro, located 75 kilometers from Cipolletti. This formation is a plateau in front setback by rain and wind erosion. It is composed of various canyons with walls more than 50 meters deep, where you can see the geological age of up to 100 million years ago, with remains of fish, turtles, crocodiles and, of course, dinosaurs from the Late Cretaceous.
Five kilometers from the Anfiteatro is the Refuge Puesto Parada, ready to receive visitors with basic services. If you continue the road 7 kilometers, visitors can enjoy Puesto Carús a haven of petrified logs, perhaps pine, located in front of the plain. This feature is given by a process called silicified: replacement of timber trees for minerals in specific conditions of humidity.
The Anfiteatro has extended his appeal from an examination conducted in 2005, which fossil remains were found dating back 75 million years between the discovery of a new species of freshwater turtle. By analyzing the remains of his shell is estimated to have a weight of 40 kilograms and a length of 55 centimeters.
The materials found are being studied and you can find it at the Carlos Ameghino Museum in Cipolletti, located in Mengelle 2000. The Museum offers a library, two halls of paleontology and two of Patagonian fauna.
