Description
The Buda Limestone is a dense white to yellow sparry limestone with numerous calcite veins that weathers to yellowish or pinkish due to its iron content. In far western Texas, the formation overlies the Del Rio Formation and is in turn overlain by the Eagle Ford Group. The total thickness is about 100 feet (30 m).[1][4] In trans-Pecos Texas, the formation rests on the Grayson Formation and is overlain by the Boquillas Formation.[5]
In the
Fossils
Exposures in Hays County, Texas have yielded fossil remains of Pterodactyloidea, Ornithocheiroidea and Ornithocheiridae.[3]
Type locality for Graptocarcinus texanus Roemer, 1887[7](Decapoda: Brachyura).

History of investigation
The formation was originally named the Shoal Creek Limestone, but this name was preempted, and the formation was renamed the Buda Limestone by T.W. Vaughan in 1900.[1] By 1935, the formation had been included in the Washita Group.[10]
