Shaded relief map of the Llano Estacado. Texas contains a wide variety of geologic settings. The state's stratigraphy has been largely influenced by marine transgressive-regressive cycles during the Phanerozoic, with a lesser but still significant contribution from late Cenozoic tectonic activity, as well as the remnants of a Paleozoic mountain range.
The Glen Rose Formation is a shallow marine to shoreline geological formation from the lower Cretaceous period exposed over a large area from South Central to North Central Texas. The formation is most widely known for the dinosaur footprints and trackways found in the Dinosaur Valley State Park near the town of Glen Rose, Texas , southwest of ...

Llano Uplift - geologic map. The Llano Uplift can be considered an uplift by either its pattern on a geological or structural map of the top of the Precambrian rocks. It qualifies as an uplift because it consists of an extensive Precambrian basement high that is exposed by virtue of its surface lying significantly above in elevation the surface of surrounding Precambrian basement.
The Arroyo Formation, sometimes termed the Lower Clear Fork Formation, is a geologic formation in Texas. [1] It preserves fossils dating back to the Kungurian stage of the Permian period . [ 2 ] It is the lower-most portion of the Clear Fork Group , part of a series of fossiliferous Permian strata in the south-central United States known as the ...
The Texas and Oklahoma red beds are sedimentary rocks, mostly consisting of sandstone and red mudstone. [8] The red color of the rocks is due to the presence of ferric oxide . [ 9 ] The rocks were deposited during the early Permian in a warm, moist climate, [ 10 ] with seasonal periods of dry conditions.
Paluxy Formation stratigraphic column in Texas. The Paluxy Formation is a geological formation found in Texas, Louisiana, Arkansas, Mississippi and Oklahoma, whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. [4]
The Paluxy River, also known as Paluxy Creek, is a river in the U.S. state of Texas.It is a tributary of the Brazos River.It is formed by the convergence of the North Paluxy River and the South Paluxy River near Bluff Dale, Texas in Erath County and flows a distance of 29 miles (47 km) before joining the Brazos just to the east of Glen Rose, Texas in south central Somervell County.
