The Lecho Formation is a geological formation in Argentina whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
According to Frankfurt and Chiappe (1999), the Lecho Formation is located in northwestern Argentina and is composed of reddish sandstones. The Lecho is part of the Upper/Late Cretaceous Balbuena Subgroup (Salta Group), which is a near-border stratigraphic unit of the Andean sedimentary basin. The paleoenvironment was a fluvio-lacustrine coastal plain. Fossils from this formation include the titanosaur Saltasaurus along with a variety of avian and non-avian theropods.
