Bajo de la Carpa Formation, Geological formation in Neuquén Province, Argentina.
Bajo de la Carpa Formation is a geological unit in Neuquén Province made up of thick sandstone layers that spread across northern Patagonia. The rock sequence displays an interesting arrangement of deposits with geodes and chemical nodules embedded throughout.
This formation took shape during the Santonian age, roughly 86 to 83 million years ago, as part of the Rio Colorado Subgroup within the Neuquén Group. These deposits record the geological evolution of the Neuquén Basin across vast spans of time.
Scientists regularly conduct field studies at this location to investigate fossils of titanosaurs, reptiles, and fish from the Late Cretaceous period.
Visitors can reach the formation using established paths throughout Neuquén Province, with the drier months providing the best conditions for exploration. The area requires basic preparation and suitable equipment for field visits in this remote region.
The sediments preserve fossilized raindrop impressions and ancient soil layers that offer direct clues about environmental conditions from millions of years ago. These rare traces allow scientists to reconstruct past climates and habitats.
