Paluxy Formation. Sandstone, mudstone, and limestone. Sandstone, fine- to very fine-grained, friable to calcite cemented, cross-beds common, in part massive, locally burrowed, light gray to greenish gray; weathers yellowish brown to dusky brown. Mudstone, sandy, massive, locally burrowed, greenish gray, olive green, and medium gray; weathers yellowish brown and red brown. Limestone locally in upper 40 to 50 feet, sandy, fossiliferous, beds 0.5 to 2 feet thick, yellowish gray; weathers mottled dark gray and yellowish brown. Thickness 95 to 105 feet. Lies above Glen Rose Formation and below Walnut Clay. Age is Early Cretaceous.

In the study area, the Paluxy is between 1100 and 1450 ft thick. The top of the formation is found at an average subsea elevation of -9400 ft. Section consists of alternating layers of sands, siltstones, and shales. The sands are quite abundant, with lenses 30 to 50 ft thick. Overlies Mooringsport Formation and underlies undifferentiated Washita-Fredericksburg Formations. No production in West Raymond Field. Age is Early Cretaceous (Comanchean).
