Buda Limestone

Buda Limestone Stratigraphic range: Late Cretaceous (Cenomanian)
Type	Geological formation
Location
Region	North America
Country	United States

The Buda Limestone is a geological formation in the High Plains and Trans-Pecos regions of West Texas whose strata date back to the Late Cretaceous. Pterosaur remains are among the fossils that have been recovered from the formation.

A stratigraphic column at the Mount Bonnell Fault location starts with the Lower Cretaceous Trinity Group overlain by the Edwards Group and the Georgetown Formation. Upper Cretaceous formations follow, starting with the Del Rio Clay, Buda Limestone, and then the Eagle Ford Group. Formations within the Trinity Group include the Hammett Formation, Cow Creek Formation, Hensel Formation, and Lower and Upper Glen Rose Formation. Formations within the Edwards Group include the Kainier Formation and the Person Formation. The Upper Cretaceous rock units confine the Edwards Aquifer within the Edwards Group and Georgetown Formation.
