这两个公园相邻，坐落在阿根廷中部彭巴山 (the Sierra Pampeanas) 西麓的沙漠地区，绵延275 300公顷，保存有三叠纪（2.45亿至2.08亿年前）最为完整的大陆化石。公园内的六个地质层含有哺乳动物先祖、恐龙以及各种植物化石，反映了脊椎动物的进化过程以及三叠纪时期古代自然环境。

These two contiguous parks, extending over 275,300 ha in the desert region on the western border of the Sierra Pampeanas of central Argentina, contain the most complete continental fossil record known from the Triassic Period (245-208 million years ago). Six geological formations in the parks contain fossils of a wide range of ancestors of mammals, dinosaurs and plants revealing the evolution of vertebrates and the nature of palaeo-environments in the Triassic Period.
