This list of the Paleozoic life of Texas contains the various prehistoric life-forms whose fossilized remains have been reported from within the US state of Texas and are between 538.8 and 252.17 million years of age.
Acrocanthosaurus.. Archaeologist Jack. T. Hughes has found evidence that the paleo-Indians of Texas collected fossils. [20] After the establishment of paleontology as a formal science, in 1878, professor Jacob Boll made the first scientifically documented Texan fossil finds in Archer and Wichita counties while collecting fossils on behalf of Edward Drinker Cope.
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.
Dinosaur and crocodilian remains are among the fossils that have been recovered from the formation. [5] This fossil formation preserves organisms that were endemic to Appalachia. [6] The Woodbine Group was first mapped and named by Robert T. Hill, known as the "Father of Texas Geology", for outcrops near the small town of Woodbine, Texas in ...

Only one geological site in the Javelina Formation has thus far yielded the correct rock types for radiometric dating. The outcrop, situated in the middle strata of the formation about 90 meters below the K-Pg boundary and within the local range of Alamosaurus fossils and below two sites that have yielded Quetzalcoatlus fossils, was dated to 69 ...
The oldest fossils in the DFW metroplex can be collected at Mineral Wells Fossil Park NW of Fort Worth. These fossils include well preserved Pennsylvanian marine fossils such as crinoids and brachiopods, which have been dated to 300 million years old. [4] [5] Remnants of dinosaurs and Late Cretaceous marine reptiles such as Mosasaur are found.
Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
