Bajada Colorada Formation

The Bajada Colorada Formation contains red and greenish-brown conglomerates along with thick-bedded sandstones, displaying various claystone colors including reddish and pinkish grey.

First documented by Roll in 1939, this formation dates back to the Late Berriasian to Early Valanginian period, approximately 140 to 134 million years ago.

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

Located at coordinates 39°48'S latitude and 69°42'W longitude, the formation rises approximately 1,404 feet above sea level and remains accessible for research purposes.

X-ray diffraction analysis reveals the presence of specific minerals within the sediments, including smectite, chlorite, illite, and kaolinite throughout the formation.
