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.
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).

The most prolific fossil site in the red beds is the Geraldine Bonebed within the Nocona Formation of the Wichita Group. [6] During the Permian, the bonebed was the site of a freshwater pond. After a catastrophic event this became the burial site for a variety of terrestrial and marine animals. [15]

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.
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.
San Pedro High School discovered a deposit of marine fossils on campus in 2022 and began collaborating with local paleontologists to uncover secrets from the Palos Verdes Peninsula's geological past.
Woodbine Formation located between Dallas and Fort Worth consists of marine and terrestrial fossils such as concretions and trace fossils, including the last known dinosaurs in this part of Texas. Directly east of the Woodbine is the Eagle Ford, where fossilized shark teeth, plesiosaurs, crabs, and small marine lizards called Coniasaurus can be ...
