The creation of this municipal museum was decreed in 1971 and has very many valuable regional objects and pieces coming from deep search and investigation. It exhibits zoological, anthropological and mineral collections as well as paleontology specimens, insects and mollusks collections and fossils from the quaternary period.
The Museum today has more than 1,000 collection pieces many of them obtained during periods of great draught between 1972 and 1980 in the course of the Salado River. Many fossils and whole skeletons were found during those years in the river. The exhibited material was widened when many collections of minerals and fossils from the Tertiary and Secondary periods were donated by The Mineral Museum from Zapala, which, together with fossilized leaves donated by the La Plata Museum have an estimated age of 80 million years.
There is also an exhibition of elements from the Huarpes Indians from the Cuyo Region, Provinces of Mendoza and San Juan specially ceramics, pieces from the Diaguitas culture from Catamarca Province and Aymara Culture from Jujuy Province and hunting balls (“boleadoras”) found in the areas around the city and in the Salado River.
There is also a collection of Ecuadorian ceramics probably one of the best in the country, fossils from the Argentine Antartica and elements from the Indians from Tierra del Fuego received as donations in 1988. There is a search still going on for fossils in the Salado River and Canal 11 and other places in the area where it is feasible to find them.
