Ituzaingó Formation

The Ituzaingó Formation is a geological layer in Corrientes made up of mudstones, sandstones, and other sedimentary rocks. These deposits formed when rivers and lakes dominated the region, leaving behind distinct layers of different materials.

This formation dates to the late Miocene and was first scientifically described in the mid-20th century. Within it lies the Conglomerado Osífero layer, which contains numerous vertebrate fossils from that ancient time.

Scientists from Argentina and neighboring countries regularly conduct research at this site to study South American prehistoric ecosystems and geological evolution.

The best way to understand the site is to examine the different layers that make up the formation and how they sit alongside each other. Visitors should keep in mind that the formation spreads across large areas, and different sections show different features.

The fossils here show connections to prehistoric animals that also lived in distant regions, suggesting ancient ecological relationships. This pattern helps scientists understand how animals were linked across vast distances.
