Los Blanquitos Formation, Geological formation in Salta Province, Argentina.
Los Blanquitos Formation is a geological layer in Salta Province composed of sandstones with quartz inclusions and carbonate veins running through multiple levels. The deposits contain fossilized remains of ancient creatures embedded in reddish and greenish-gray rock layers.
This formation dates back to the Late Cretaceous period, roughly 80 million years ago. It formed in shallow seas or river systems that once covered northern Argentina.
Paleontologists and geologists visit this formation regularly to examine fossils preserved in its layers. The site attracts specialists interested in understanding ancient life and environmental conditions from that era.
This layer is accessible in the open landscape and displays its structure clearly in exposed rock faces. Visitors should prepare for uneven terrain and variable weather conditions.
Fossils in this formation are often surrounded by a distinctive greenish or grayish rock halo that contrasts sharply with the red sediment nearby. This feature makes it easier for researchers to spot fossilized remains.
