Description
Source: Wikipédia
La Formation de Los Colorados est une formation géologique de roches sédimentaires située en Argentine dans la province de La Rioja. Des analyses magnétostratigraphiques indiquent que la Formation de Los Colorados s'est déposée entre il y a 227 et 213 millions d'années, durant le Norien (Trias supérieur).
Cette formation est remarquable pour ses fossiles de dinosaures primitifs, notamment le coelophysoidé Zupaysaurus et les sauropodomorphes Coloradisaurus, Lessemsaurus, et Riojasaurus. Des restes de l'aétosaure Neoaetosauroides y ont été découverts.

Quebrada del Viento : La Rioja - ? 37144 Quebrada del Viento- Quebrada de los Jachaleros : La Rioja - ? 8988 13000 24702 Locality is given as "Quebrada de los Jachaleros, 7 km W of R.N. 126, La Rioja province, Argentina" by Ezcurra & Novas (2007) and Arcucci & Coria (2003). However, according to Arcucci et al. (2004) the locality is "NW of La Esquina and SE of El Salto" and is different to the classic "Quebrada de los Jachaleros" which is nearby, but in San Juan state.
