Woodbine Formation
The Woodbine Group is a geological formation in east Texas whose strata date back to the Early to Middle Cenomanian age of the Late Cretaceous. It is the producing formation of the giant East Texas Oil Field (also known as the "Black Giant") from which over 5.42 billion barrels of oil have been produced. The Woodbine overlies the Maness Shale, Buda Limestone, or older rocks, and underlies the Eagle Ford Group or Austin Chalk. In outcrop the Woodbine Group has been subdivided into the Lewisville Sandstone, Dexter Sandstone, and/or Pepper Shale formations. Thin-bedded sands of the Woodbine and Eagle Ford are collectively referred to as the "Eaglebine" oil and gas play in the southwestern portion of the East Texas region. Dinosaur and crocodilian remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)."

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Austin Chalk
The Austin Chalk is an upper Cretaceous geologic formation in the Gulf Coast region of the United States. It is named after type section outcrops near Austin, Texas. The formation is made up of chalk and marl. Fossils The putative galloanseran bird ''Austinornis lentus'' has been found in the Austin Chalk.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. 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). Nevertheless, the Austin Chalk will occasionally produce fossils of larger creatures, such as ''Inoceramus'' clams, ammonite cephalopods, and large marine vertebrates such as ''Xiphactinus'', a predaceous fish. Geology The rocks of the Austin Chalk consist of recrystallized, fossiliferous, interbedded chalks and m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deltasuchus
''Deltasuchus'' ("delta crocodile") is a genus of neosuchian crocodyliform from the Late Cretaceous of Texas, specifically in the Woodbine Formation, which was a part of the Appalachian continent during the Cretaceous. It is known from one species, ''D. motherali'', named in 2017 by Thomas Adams, Christopher Noto, and Stephanie Drumheller. In 2021, new material was described, allowing ''Deltasuchus'' to be placed within the family Paluxysuchidae as the sister taxon to ''Paluxysuchus ''Paluxysuchus'' is an extinct genus of neosuchian crocodyliform known from the Early Cretaceous Twin Mountains Formation (late Aptian stage) of north-central Texas.

Theropod
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic period 231.4 million years ago ( Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of diets was historically considered a characteri ...

Woodbinesuchus
''Woodbinesuchus'' (meaning "Woodbine Formation crocodile") is an extinct genus of goniopholidid mesoeucrocodylian. Its fossils have been recovered from the Cenomanian-age Upper Cretaceous Woodbine Formation of Texas. Crocodyliform fossils are widespread in the formation. The type specimen of ''Woodbinesuchus'', SMU 74626, came from near the base of the formation in Tarrant County. It was found by Johnny Allen Byers (Ted & Mary's favorite boy) and J. Maurice in May 1990. The specimen includes the lower jaw and a variety of postcranial elements, such as vertebrae, limb bones, shoulder and hip bones, and bony armor. The lower jaw was elongate and slender, with the two halves joined from the tip to the sixteenth teeth, and there was no mandibular fenestra. Yuong–Nam Lee named ''Woodbinesuchus'' in 1997, naming the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered ...

Dallasaurus
''Dallasaurus'' ("Dallas lizard") is a basal mosasauroid from the Upper Cretaceous of North America. Along with ''Russellosaurus'', ''Dallasaurus'' is one of the two oldest mosasauroid taxa currently known from North America. It is also the smallest known mosasaurine, measuring up to in length and in body mass. Specimens The genus is based upon two partial skeletons recovered from the Arcadia Park Shale (lower Middle Turonian), approximately 15 meters above its contact with the older Kamp Ranch Limestone in Dallas County in north-central Texas. The holotype specimen (TMM 43209-1, Texas Memorial Museum, University of Texas at Austin) consists of an incomplete and disarticulated skull, along with considerable portions of the postcranial skeleton, making up about 80 percent of the animal. The second referred specimen (DMNH 8121-8125, 8143-8149, and 8161-8180, Dallas Museum of Natural History) lacks any skull material and consists entirely of disarticulated postcranial remains. T ...

Flower Mound, Texas
Flower Mound is an incorporated town located in Denton and Tarrant counties in the U.S. state of Texas. Located northwest of Dallas and northeast of Fort Worth adjacent to Grapevine Lake, the town derives its name from a prominent mound located in the center of town. After settlers used the site for religious camps during the 1840s, the area around Flower Mound was first permanently inhabited in the 1850s; however, residents did not incorporate until 1961. Although an effort to create a planned community failed in the early 1970s, Flower Mound's population increased substantially when Dallas/Fort Worth International Airport opened to the south in 1974. As of the 2020 United States census, the population was 75,956, reflecting a 17% increase over the 64,669 counted in the 2010 census. Of the Texas municipalities that label themselves "towns", Flower Mound has the largest population. Flower Mound was the only town with a population greater than 20,000 in the 2020 census. Flow ...

Protohadros
''Protohadros'' (meaning "first hadrosaur") is a genus of herbivorous ornithischian dinosaur from the Late Cretaceous ( Cenomanian stage). Gary Byrd, a part-time palaeontologist, discovered some remains of this euornithopod (ribs and an ungual) during early 1994 at Flower Mound, Denton County, north-central Texas. He informed professional palaeontologist Yuong-Nam Lee of the find, who arranged for the entire preserved fossil to be excavated. It was first reported upon in 1996 by Jason Head of the Dedman College of Humanities and Sciences, Southern Methodist University. The type species ''Protohadros byrdi'' was described and named by Head in 1998. The genus name is derived from Greek πρῶτος, ''protos'', "first", en ἁδρός, ''hadros'', "thick", a reference to the fact that Head considered the species the oldest known hadrosaur. The specific name honours Byrd. The holotype, specimen SMU 74582, of ''Protohadros'', was found in the Woodbine Formation, which date ...
