The El Picacho Formation is a geological formation in Texas, United States, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 574-588. . The paleosols found here are rich in clay, calcite, and rhizoliths which show that during the Cretaceous period, this fossil formation, just like the neighboring Javelina Formation and Aguja Formation, was a fluvial flood plain.
