Eagle Ford stratigraphic column Outcrop of the Eagle Ford and Austin Chalk Contact off Kiest Blvd, 1/2 mile east of Patriot Pky in Dallas County. The Eagle Ford Group (also called the Eagle Ford Shale) is a sedimentary rock formation deposited during the Cenomanian and Turonian ages of the Late Cretaceous over much of the modern-day state of Texas.
Wilcox Group - stratigraphy The Wilcox Group is an important geologic group in the Gulf of Mexico Basin and surrounding onshore areas from Mexico and Texas to Louisiana and Alabama . The group ranges in age from Paleocene to Eocene and is in Texas subdivided into the Calvert Bluff , Simsboro and Hooper Formations , [ 1 ] and in Alabama into the ...
Glen Rose Formation stratigraphic column in Texas. 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.
Texas is approximately bisected by a series of faults that trend southwest to northeast across the state, from the area of Uvalde to Texarkana.South and east of these faults, the surface exposures consist mostly of Cenozoic sandstone and shale strata that grow progressively younger toward the coast, indicative of a regression that has continued from the late Mesozoic to the present.
The Trinity Group is a group (sequence of rock strata) in the Lower Cretaceous lithostratigraphy of Texas, Arkansas, Mississippi, Louisiana and Oklahoma. [2] [3] [4] It is named for the Trinity River of Texas. A stratigraphic column at the Mount Bonnell Fault location starts with the Lower Cretaceous Trinity Group overlain by the Edwards Group.
Trinity Group stratigraphic column in Texas. The Hensel Formation or Hensel Sand is a Mesozoic geologic formation in Texas. Fossil ornithopod tracks have been reported from the formation. [1] A stratigraphic column at the Mount Bonnell Fault location reveals the following sequence: the Lower Cretaceous Trinity Group is overlain by the Edwards ...

The putative galloanseran bird Austinornis lentus has been found in the Austin Chalk. [2] [3] The general absence of dinosaurs is a reflection of the Austin limestone being marine in origin, primarily composed of microscopic shell fragments from floating sea organisms known as "coccolithophores" (the same organisms that contributed to the White Cliffs of Dover, on the south coast of England).
