La Colonia Formation

The La Colonia Formation contains layers of sandstone, shale, and mudstone that extend up to 240 meters in thickness across the Chubut Province.

Scientists first documented this formation during geological surveys in the 1950s, leading to numerous discoveries of Late Cretaceous period fossils.

Researchers from multiple countries gather at this location to study the diverse collection of fossils, including dinosaurs, turtles, and prehistoric plants.

The formation spans multiple research zones that require official permits and coordination with local authorities for scientific exploration and excavation.

This formation preserves over 300 mammal specimens alongside the remains of Carnotaurus sastrei, providing data about species distribution in prehistoric Patagonia.
