Bajada Colorada Formation

The Bajada Colorada Formation is a geological layer in Neuquén Province made up of reddish and greenish-brown conglomerates mixed with thick sandstone beds. The rocks display varying colors from red and pink to grey, creating a visible pattern across the exposed surfaces.

This rock layer formed during the Early Jurassic period roughly 140 to 134 million years ago and was first scientifically documented in 1939. The formation developed in a river-fed environment with changing deposit conditions.

The formation holds scientific importance as the discovery site of multiple dinosaur species, including Bajadasaurus pronuspinax, Leinkupal laticauda, and Ninjatitan zapatai.

The area is raw open land with few facilities, so sturdy clothing and water are essential when visiting. It is best to explore during warmer months when road access to the site is more straightforward.

The site produced several newly identified dinosaur species including Bajadasaurus and other large plant-eaters from the Early Jurassic. These discoveries have helped scientists understand better how dinosaurs developed in this region during that time.
