Platygonus
''Platygonus'' ("flat head" in reference to the straight shape of the forehead) is an extinct genus of herbivorous peccaries of the family Tayassuidae, endemic to North and South America from the Miocene through Pleistocene epochs (10.3 million to 11,000 years ago), existing for about . ''P. compressus'' stood 2.5 feet (0.75 meters) tall. Description Most ''Platygonus'' species were similar in size to modern peccaries especially giant peccary, at around in body length, and had long legs, allowing them to run well. They also had a pig-like snout and long tusks which were probably used to fend off predators. Taxonomy While long thought to be the sister-lineage to the Chacoan peccary based on morphological similarities, a 2017 ancient DNA study which recovered mitochondrial DNA from ''Platygonus'' found that all living peccaries are more closely related to each other than they are to ''Platygonus''. The estimated divergence between ''Platygonus'' and all living peccaries was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platygonus Compressus
''Platygonus compressus'', the flat-headed peccary, is an extinct mammal species from the Tayassuidae family, that lived in North-America during the Pleistocene. It was first described in 1848 by John L. Leconte. Description The flat-headed peccary was about 75 cm (29.5 in) in shoulderheight and about 30 kg (66.1 lb) in weight. Other sources have estimated it to be similar in size to the European Wild Boar. Sizes differ between the place they have been found. Fossil skulls suggest a small brain, but a good sense of smell and sight. It has been suggested that the nasal cavity provided filtration for cold, dry and dusty air. ''Platygonus compressus'' had elongated limbs, a short humerus, broad and erect thoracic vertebrae and a large scapula. Therefore it has been suggested that this species may have been fleeter on foot than modern peccary species. Otherwise they probably appeared very similar to their closest living relative, the Chacoan peccary. Gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peccary
A peccary (also javelina or skunk pig) is a medium-sized, pig-like hoofed mammal of the family Tayassuidae (New World pigs). They are found throughout Central and South America, Trinidad in the Caribbean, and in the southwestern area of North America. They usually measure between in length, and a full-grown adult usually weighs about . They represent the closest relatives of the family Suidae, which contains pigs and relatives. Together Tayassuidae and Suidae are grouped in the Suina within the Artiodactyla (even toed ungulates). Peccaries are social creatures that live in herds. They eat roots, grubs, and a variety of foods. They can identify each other by their strong odors. A group of peccaries that travel and live together is called a "squadron". A squadron of peccaries averages between six and nine members. Peccaries first appeared in North America during the Miocene, and migrated into South America during the Pliocene-Pleistocene as part of the Great American In ...

Kansas
Kansas () is a state in the Midwestern United States. Its capital is Topeka, and its largest city is Wichita. Kansas is a landlocked state bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, which in turn was named after the Kansa Native Americans who lived along its banks. The tribe's name (natively ') is often said to mean "people of the (south) wind" although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison. The first Euro-American settlement in Kansas occurred in 1827 at Fort Leavenworth. The pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery deba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic p ...

Beecher Island
Beecher Island is a sandbar located along the lower course of the Arikaree River, a tributary of the North Fork of the Republican River near Wray in Yuma County, Colorado. The site is notable for having been the scene of an 1868 armed conflict between elements of the United States Army and several of the Plains Indian tribes. The island was named for Lt. Fredrick Henry Beecher of the 3rd Infantry (nephew of Henry Ward Beecher and veteran of the Battle of Gettysburg), one of the heroes of the engagement who was killed during what became known as the Battle of Beecher Island. The "island" and the courses of the river have been modified by several floods since 1868. The Battle of Beecher Island was fought along the Arickaree Fork of the Republican River with concentrated fighting on a small island. A few willow trees stood on the island; however, the banks on either side of the river were believed to have had minimal tree growth. Bluffs rise gently from the course of the ...
