Chapalmalania
''Chapalmalania'' is an extinct genus of procyonid from the Pliocene (Chapadmalalan to Uquian) of Argentina and Colombia (Ware Formation, Cocinetas Basin, La Guajira). Description Though related to raccoons and coatis, ''Chapalmalania'' was a large creature, reaching about in body length, with a short tail. ''Chapalmalania'' is estimated to have weighed approximately , comparable in size to an American black bear (''Ursus americanus''). Due to its size, its remains were initially identified as those of a bear. It evolved from the "dog-coati" ''Cyonasua'', which probably island-hopped from Central America during the late Miocene (7.5 million years ago), as perhaps the earliest southward mammalian migrants of the Great American Interchange. When the Isthmus of Panama rose from the sea to allow further invasions by other North American species, ''Chapalmalania'' was unable to compete and its lineage became extinct. ''Chapalmalania'' is thought to have had an omnivorous diet simi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyonasua
''Cyonasua'' (meaning "dog-coati" in Greek) is an extinct genus of procyonid from the Late Miocene to Middle Pleistocene of South America. Fossils of ''Cyonasua'' have been found in Argentina ( Ituzaingó, Epecuén, Huayquerías, Monte Hermoso, Chapadmalal, Maimará, Ensenada, La Playa, Chiquimil, Andalhuala, and Cerro Azul Formations), Bolivia ( Tariquía Formation), Uruguay ( Camacho Formation), and Venezuela ( San Gregorio Formation). The oldest well-dated fossils of ''Cyonasua'' are approximately 7.3 million years old. Most fossils of ''Cyonasua'' are late Miocene to early late Pliocene (Huayquerian to Chapadmalalan SALMAs, 7.3-3 million years old) in age, but a single early Pleistocene specimen (the holotype and only known specimen of ''Cyonasua meranii'') indicates that members of this genus survived until at least 0.99 million years ago (the fossil layer where this specimen was collected dating to the Jaramillo Chron). ''Cyonasua'' is the oldest terrestrial carnivoran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cocinetas Basin
The Cocinetas Basin ( es, Cuenca Cocinetas) is a small sedimentary basin of approximately in northeasternmost Colombia. The onshore pull-apart basin is located in the department of La Guajira at the border with Zulia, Venezuela. The basin is bound by three sets of hills; the Serranía de Jarara, Serranía Macuira and Serranía Cocinas, with the eastern boundary formed by the Gulf of Venezuela, part of the Caribbean Sea. The basin was formed during the Paleogene as a result of the eastward movement of the Caribbean Plate along the northern edge of the South American Plate, leading to the deposition of a Middle Eocene to Middle Pleistocene sedimentary sequence of conglomerates, sandstones, siltstones, limestones and mudstones. In the Cocinetas Basin, several fossiliferous stratigraphic units have been registered, providing an abundance of marine and continental vertebrate and invertebrate fossil fauna assemblages. The Uitpa, Jimol, Castilletes and Ware Formations contain numerou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Procyonidae
Procyonidae is a New World family of the order Carnivora. It comprises the raccoons, ringtails, cacomistles, coatis, kinkajous, olingos, and olinguitos. Procyonids inhabit a wide range of environments and are generally omnivorous. Characteristics Procyonids are relatively small animals, with generally slender bodies and long tails, though the common raccoon tends to be bulky. Because of their general build, the Procyonidae are often popularly viewed as smaller cousins of the bear family. This is apparent in their German names: a raccoon is called a ''Waschbär'' (washing bear, as it "washes" its food before eating), a coati is a ''Nasenbär'' (nose-bear), while a kinkajou is a ''Honigbär'' (honey-bear). Dutch follows suit, calling the animals ''wasbeer'', ''neusbeer'' and ''rolstaartbeer'' respectively. However, it is now believed that procyonids are more closely related to mustelids than to bears. Procyonids share common morphological characteristics including a shortened ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great American Interchange
The Great American Biotic Interchange (commonly abbreviated as GABI), also known as the Great American Interchange and the Great American Faunal Interchange, was an important late Cenozoic paleozoogeographic biotic interchange event in which land and freshwater fauna migrated from North America via Central America to South America and vice versa, as the volcanic Isthmus of Panama rose up from the sea floor and bridged the formerly separated continents. Although earlier dispersals had occurred, probably over water, the migration accelerated dramatically about 2.7 million years ( Ma) ago during the Piacenzian age. It resulted in the joining of the Neotropic (roughly South American) and Nearctic (roughly North American) biogeographic realms definitively to form the Americas. The interchange is visible from observation of both biostratigraphy and nature (neontology). Its most dramatic effect is on the zoogeography of mammals, but it also gave an opportunity for reptiles, amphibia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ware Formation
The Ware Formation ( es, Formación Ware) is a fossiliferous geological formation of the Cocinetas Basin in the northernmost department of La Guajira. The formation consists of fine lithic to quartzitic sandstones, mudstones, pebbly conglomerates with sedimentary and metamorphic rock fragments, fossiliferous packstones and sandy to conglomeratic beds with high fossil content. The Ware Formation dates to the Neogene and Quaternary periods; Late Miocene to Early Pleistocene epochs, typically Pliocene (3.5 to 2.8 Ma), Uquian, Chapadmalalan and Montehermosan in the SALMA classification, and has a maximum thickness of . Etymology The formation was defined in 2015 by Moreno et al., and given the name Ware, meaning "friend" in Wayuunaiki, the language of the local indigenous Wayuu, meaning "friend". The name has been given to pay tribute to the friendship between Colombia and Venezuela.Moreno et al., 2015, p.32 Description Lithologies The Ware Formation consists of fine lithic to q ...

Prehistoric Carnivoran Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Central America
Central America ( es, América Central or ) is a subregion of the Americas. Its boundaries are defined as bordering the United States to the north, Colombia to the south, the Caribbean Sea to the east, and the Pacific Ocean to the west. Central America consists of eight countries: Belize, Costa Rica, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, and Panama. Within Central America is the Mesoamerican biodiversity hotspot, which extends from northern Guatemala to central Panama. Due to the presence of several active geologic faults and the Central America Volcanic Arc, there is a high amount of seismic activity in the region, such as volcanic eruptions and earthquakes which has resulted in death, injury, and property damage. In the pre-Columbian era, Central America was inhabited by the indigenous peoples of Mesoamerica to the north and west and the Isthmo-Colombian peoples to the south and east. Following the Spanish expedition of Christopher Columbus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piacenzian Extinctions
The Piacenzian is in the international geologic time scale the upper stage or latest age of the Pliocene. It spans the time between 3.6 ± 0.005 Ma and 2.588 ± 0.005 Ma (million years ago). The Piacenzian is after the Zanclean and is followed by the Gelasian (part of the Pleistocene). The Piacenzian is roughly coeval with the European land mammal age MN 16, overlaps the late Chapadmalalan and early Uquian South American land mammal age and falls inside the more extensive Blancan North American land mammal age. It also correlates with the Astian, Redonian, Reuverian and Romanian regional stages of Europe. Some authorities describe the British Red Crag Formation and Waltonian Stage as late Piacenzian, while others regard them as early Pleistocene. Carbon dioxide levels during the Piacenzian were similar to those of today, making this age, with global mean temperature 2–3 °C higher and sea levels about twenty meters higher than today, an important analogue for predictions of the ...

Simon & Schuster
Simon & Schuster () is an American publishing company and a subsidiary of Paramount Global. It was founded in New York City on January 2, 1924 by Richard L. Simon and M. Lincoln Schuster. As of 2016, Simon & Schuster was the third largest publisher in the United States, publishing 2,000 titles annually under 35 different imprints. History Early years In 1924, Richard Simon's aunt, a crossword puzzle enthusiast, asked whether there was a book of ''New York World'' crossword puzzles, which were very popular at the time. After discovering that none had been published, Simon and Max Schuster decided to launch a company to exploit the opportunity.Frederick Lewis Allen, ''Only Yesterday: An Informal History of the 1920s'', p. 165. . At the time, Simon was a piano salesman and Schuster was editor of an automotive trade magazine. They pooled , equivalent to $ today, to start a company that published crossword puzzles.

Carrion
Carrion () is the decaying flesh of dead animals, including human flesh. Overview Carrion is an important food source for large carnivores and omnivores in most ecosystems. Examples of carrion-eaters (or scavengers) include crows, vultures, condors, hawks, eagles, hyenas, Virginia opossum, Tasmanian devils, coyotes and Komodo dragons. Many invertebrates, such as the carrion and burying beetles, as well as maggots of calliphorid flies (such as one of the most important species in '' Calliphora vomitoria'') and flesh-flies, also eat carrion, playing an important role in recycling nitrogen and carbon in animal remains. Carrion begins to decay at the moment of the animal's death, and it will increasingly attract insects and breed bacteria. Not long after the animal has died, its body will begin to exude a foul odor caused by the presence of bacteria and the emission of cadaverine and putrescine. Some plants and fungi smell like decomposing carrion and attract insects that a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
