It has an area of 603.7 km², most of them within the Valle Fértil Department, with a minor part in the Jachal Department of San Juan, at an altitude of about 1,300 m above mean sea level. The park is part of the western border of the Pampean Hills, and it features typical desert vegetation (bushes, cacti and some trees) which covers between 10 and 20% of the area. The climate is very dry, with rainfall mostly during the summer, and temperature extremes (minimum -10 °C, maximum 45 °C). There is a constant southern wind with a speed of 20-40 km/h after noon and until the evening, sometimes accompanied by an extremely strong zonda wind.

Importance

The Ischigualasto Formation contains Late Triassic (Carnian) deposits (230 million years before the present), with some of the oldest known dinosaur remains, which are the world's first with regards to quality, number and importance. It is the only place in the world where nearly all of the Triassic is represented in an undisturbed sequence of rock deposits. This allows for the study of the transition between dinosaurs and ancient mammals; research is ongoing. The Triassic is a geologic period that extends from about 251 ± 0. ... The Carnian is a stage on the geologic time scale occuring from 228 +/- 2 to 216. ...

The arid badlands around the formation are known as Valle de la Luna ("Valley of the Moon") due to their rugged, otherworldly appearance. In the Carnian this area was a volcanically active floodplain dominated by rivers and had a strongly seasonal rainfall. Petrified tree trunks of Protojuniperoxylon ischigualastianus more than 40 meters tall attest to a rich vegetation at that time. Fossil ferns and horsetails have also been found.

Species The horsetails are vascular plants, comprising 15 species of plants in the genus Equisetum. ...

Rhyncosaurs and cynodonts are by far the predominant findings among the tetrapod fossils in the park. Dinosaurs comprise only 6% of the findings, but these include early samples of the two major lineages of dinosaurs (ornithischians and saurischians). The carnivorous archosaur Herrerasaurus is the most numerous of these dinosaur fossils. Another important putative dinosaur with primitive characteristics is Eoraptor lunensis, found in Ischigualasto in the early 1990s. Clades Procynosuchidae Epicynodontia Galesauridae Eucynodontia Cynognathia Cynognathidae Tritylodontidae Probainognathia Trithelodontidae Mammaliformes Cynodonta, or dog teeth, were one of the most diverse groups of therapsids. ...
