List Of Counties In Texas
The U.S. state of Texas is divided into 254 County (United States), counties, more than any other U.S. state. Over 20% of Texas counties are generally located within the Texas Triangle, Houston-Dallas—San Antonio—Austin areas, serving about 20,000,000 people, the majority of the state's population. Texas was originally divided into Municipalities of Mexico, municipalities (''municipios'' in Spanish language, Spanish), a unit of local government under Spain, Spanish and Mexico, Mexican rule. When the Republic of Texas gained its independence in 1836, the 23 municipalities became the original Texas counties. Many of these were later divided into new counties. The last county to be initially created was Kenedy County, Texas, Kenedy County in 1921, but Loving County, Texas, Loving County is the newest organized county; it was first organized in 1893 in an apparent scheme to defraud, abolished in 1897, then reorganized in 1931. Most of these recent counties, especially near the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monahans, Texas
Monahans is a city in and the county seat of Ward County, Texas, United States. A very small portion of the city extends into Winkler County. The population was 6,953 at the 2010 census. In 2018, the population was estimated at 7,669. History The Permian Basin, home to Monahans and Midland-Odessa combined statistical area, is wide and long; Monahans is "The Center of the Permian Basin". The basin was formed during the Permian period, the final portion of the Paleozoic era. At the time, it was an ocean filled with abundant aquatic life. In 1583, Spanish explorer Antonio de Espejo crossed this area on his way through present-day New Mexico. The Indians in the Monahans region were called ''vaqueros'' by these Spanish explorers because they hunted the "hump-backed cattle" or bison. Records of Spanish exploring the ''Los Medanos'' (the sand dunes) outside Monahans can be traced to the early 1770s. Located in a region where native Comanches, Mescalero, and Lipan Apache Indians o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-Hispanic Or Latino African Americans
African Americans (also referred to as Black Americans and Afro-Americans) are an ethnic group consisting of Americans with partial or total ancestry from sub-Saharan Africa. The term "African American" generally denotes descendants of enslaved Africans who are from the United States. While some Black immigrants or their children may also come to identify as African-American, the majority of first generation immigrants do not, preferring to identify with their nation of origin. African Americans constitute the second largest racial group in the U.S. after White Americans, as well as the third largest ethnic group after Hispanic and Latino Americans. Most African Americans are descendants of enslaved people within the boundaries of the present United States. On average, African Americans are of West/Central African with some European descent; some also have Native American and other ancestry. According to U.S. Census Bureau data, African immigrants generally do not self-ide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Non-Hispanic Or Latino Whites
Non-Hispanic whites or Non-Latino whites are Americans who are classified as "white", and are not of Hispanic (also known as "Latino") heritage. The United States Census Bureau defines ''white'' to include European Americans, Middle Eastern Americans, and North African Americans. Americans of European ancestry represent ethnic groups and more than half of the white population are German, Irish, Scottish, English , Italian , French and Polish Americans. In the United States, this population was first derived from English (and, to a lesser degree, French) settlement of the America, as well as settlement by other Europeans such as the Germans and Dutch that began in the 17th century (see History of the United States). Continued growth since the early 19th century is attributed to sustained very high birth rates alongside relatively low death rates among settlers and natives alike as well as periodically massive immigration from European countries, especially Germany, Ireland, ...

Seymouria
''Seymouria'' is an extinct genus of seymouriamorph from the Early Permian of North America and Europe. Although they were amphibians (in a biological sense), ''Seymouria'' were well-adapted to life on land, with many reptilian features—so many, in fact, that ''Seymouria'' was first thought to be a primitive reptile. It is primarily known from two species, ''Seymouria baylorensis'' and ''Seymouria sanjuanensis''. The type species, ''S. baylorensis'', is more robust and specialized, though its fossils have only been found in Texas. On the other hand, ''Seymouria sanjuanensis'' is more abundant and widespread. This smaller species is known from multiple well-preserved fossils, including a block of six skeletons found in the Cutler Formation of New Mexico, and a pair of fully grown skeletons from the Tambach Formation of Germany, which were fossilized lying next to each other. For the first half of the 20th century, ''Seymouria'' was considered one of the oldest and most "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seymouriamorpha
Seymouriamorpha were a small but widespread group of limbed vertebrates (tetrapods). They have long been considered reptiliomorphs, and most paleontologists may still accept this point of view, but some analyses suggest that seymouriamorphs are stem-tetrapods (not more closely related to Amniota than to Lissamphibia). Many seymouriamorphs were terrestrial or semi-aquatic. However, aquatic larvae bearing external gills and grooves from the lateral line system have been found, making them unquestionably amphibians. The adults were terrestrial. They ranged from lizard-sized creatures (30 centimeters) to crocodile-sized 150 centimeter long animals. They were reptile-like. If seymouriamorphs are reptiliomorphs, they were the distant relatives of amniotes. Seymouriamorphs form into three main groups, Kotlassiidae, Discosauriscidae, and Seymouriidae, a group that includes the best known genus, ''Seymouria''. The last seymouriamorph became extinct by the end of the Permian. Taxonomy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diadectes
''Diadectes'' (meaning ''crosswise-biter'') is an extinct genus of large reptiliomorphs or synapsids that lived during the early Permian period (Artinskian-Kungurian stages of the Cisuralian epoch, between 290 and 272 million years ago). ''Diadectes'' was one of the first herbivorous tetrapods, and also one of the first fully terrestrial vertebrates to attain large size. Description ''Diadectes'' was a heavily built animal, up to long, with a thick-boned skull, heavy vertebrae and ribs, massive limb girdles, and short, robust limbs. The nature of the limbs and vertebrae clearly indicates a terrestrial animal. The rib cage was assumed to be barrel-shaped, but new fossils show the ribs were actually sticking out to the sides. Paleobiology It possesses some characteristics of reptilians and amphibians, combining a reptile-like skeleton with a more primitive, seymouriamorph-like skull. ''Diadectes'' has been classified as belonging to the sister group of the amniotes. Among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dimetrodon
''Dimetrodon'' ( or ,) meaning "two measures of teeth,” is an extinct genus of non-mammalian synapsid that lived during the Cisuralian (Early Permian), around 295–272 million years ago (Mya). It is a member of the family Sphenacodontidae. The most prominent feature of ''Dimetrodon'' is the large neural spine sail on its back formed by elongated spines extending from the vertebrae. It walked on four legs and had a tall, curved skull with large teeth of different sizes set along the jaws. Most fossils have been found in the Southwestern United States, the majority coming from a geological deposit called the Red Beds of Texas and Oklahoma. More recently, its fossils have been found in Germany. Over a dozen species have been named since the genus was first erected in 1878. ''Dimetrodon'' is often mistaken for a dinosaur or as a contemporary of dinosaurs in popular culture, but it became extinct some 40 million years before the first appearance of dinosaurs.

Tetrapod
Tetrapods (; ) are four-limbed vertebrate animals constituting the superclass Tetrapoda (). It includes extant and extinct amphibians, sauropsids ( reptiles, including dinosaurs and therefore birds) and synapsids (pelycosaurs, extinct therapsids and all extant mammals). Tetrapods evolved from a clade of primitive semiaquatic animals known as the Tetrapodomorpha which, in turn, evolved from ancient lobe-finned fish (sarcopterygians) around 390 million years ago in the Middle Devonian period; their forms were transitional between lobe-finned fishes and true four-limbed tetrapods. Limbed vertebrates (tetrapods in the broad sense of the word) are first known from Middle Devonian trackways, and body fossils became common near the end of the Late Devonian but these were all aquatic. The first crown-tetrapods (last common ancestors of extant tetrapods capable of terrestrial locomotion) appeared by the very early Carboniferous, 350 million years ago. The specific aquatic ancestors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trimerorhachis
''Trimerorhachis'' is an extinct genus of dvinosaurian temnospondyl within the family Trimerorhachidae. It is known from the Early Permian of the southwestern United States, with most fossil specimens having been found in the Texas Red Beds. The type species of ''Trimerorhachis'', ''T. insignis'', was named by American paleontologist Edward Drinker Cope in 1878. Cope named a second species from Texas, ''T. mesops'', in 1896. The species ''T. rogersi'' (named in 1955) and ''T. greggi'' (named in 2013) are also from Texas, and the species ''T. sandovalensis'' (named in 1980) is from New Mexico. Description The length of the largest specimens of ''Trimerorhachis'' is estimated to have been almost a metre (3.3 feet) in length. ''Trimerorhachis'' has a large triangular head with upward-facing eyes positioned near the front of the skull. The trunk is long and the limbs are relatively short. The presence of a branchial apparatus indicates that ''Trimerorhachis'' had external gills in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Cisuralian
The Cisuralian is the first Series (stratigraphy), series/Epoch (geology), epoch of the Permian. The Cisuralian was preceded by the Pennsylvanian (geology), Pennsylvanian and followed by the Guadalupian. The Cisuralian Epoch is named after the western slopes of the Ural Mountains in Russia and Kazakhstan and dates between 298.9 ± 0.15 – 272.3 ± 0.5 Mya. The Cisuralian is often synonymous with the informal terms early Permian or lower Permian. It corresponds approximately with the Wolfcampian in southwestern North America. The series saw the appearance of beetles and Fly, flies and was a relatively stable warming period of about 21 million years. Name and background The Cisuralian is the first series or epoch of the Permian. The Cisuralian was preceded by the last Pennsylvanian epoch (Gzhelian) and is followed by the Permian Guadalupian Epoch. The name "Cisuralian" was proposed in 1982, and approved by the International Subcommission on Permian Stratigraphy in 1996. The Ci ...
