Nuciruptor Rubricae
''Nuciruptor'' is an extinct genus of New World monkeys from the Middle Miocene ( Laventan in the South American land mammal ages; 13.8 to 11.8 Ma). Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is ''N. rubricae''.''Nuciruptor rubricae'' in the Paleobiology Database Etymology The name ''Nuciruptor rubricae'' is derived from the Latin ''nuci'' ("nut") and ''ruptor'' meaning "to break".Kay & Meldrum, 1997, p.409 ''Rubricae'' refers to the red beds where the fossils have been found.[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Premolar
The premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth. In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth. They have at least two cusps. Premolars can be considered transitional teeth during chewing, or mastication. They have properties of both the canines, that lie anterior and molars that lie posterior, and so food can be transferred from the canines to the premolars and finally to the molars for grinding, instead of directly from the canines to the molars. Human anatomy The premolars in humans are the maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar. Premolar teeth by definition are permanent teeth distal to the canines, preceded by deciduous molars. Morphology There is always one large buccal cusp, especially so in the mandibular first premolar. The lower second ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Hartwig
Walter Carl Hartwig is an American anthropologist, paleontologist, anatomy professor and author in the San Francisco Bay Area. In July 2020 he became Director of Enrollment Management and Student Success at Touro University California's College of Osteopathic Medicine, where he has served professionally for 25 years. Walter Hartwig graduated summa cum laude in anthropology at the University of Missouri in 1986. He undertook graduate work in biological anthropology under the late Francis Clark Howell at the University of California at Berkeley in 1986, where he developed an interest in South American monkeys. Academic career Fieldwork in Colombia introduced Hartwig to Alfred L. Rosenberger, who soon became a mentor and colleague with whom he collaborated through 2011. Hartwig’s early publications emerged from their shared interest in the fossil record of South American monkeys, of which Hartwig once was an international authority. Hartwig turned to comparative cranial anat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It was established in 1918 by Aleš Hrdlička (U.S. National Museum, now the Smithsonian Institution's National Museum of Natural History). The journal covers the field of biological anthropology, a discipline which Hrdlička defined in the first issue as "the study of racial anatomy, physiology and pathology." The Wistar Institute of Anatomy and Biology was the original publisher. Before launching publication, there were few outlets in the United States to publish scientific work in physical anthropology.

Smithsonian Institution
The Smithsonian Institution ( ), or simply the Smithsonian, is a group of museums and education and research centers, the largest such complex in the world, created by the U.S. government "for the increase and diffusion of knowledge". Founded on August 10, 1846, it operates as a trust instrumentality and is not formally a part of any of the three branches of the federal government. The institution is named after its founding donor, British scientist James Smithson. It was originally organized as the United States National Museum, but that name ceased to exist administratively in 1967. Called "the nation's attic" for its eclectic holdings of 154 million items, the institution's 19 museums, 21 libraries, nine research centers, and zoo include historical and architectural landmarks, mostly located in the District of Columbia. Additional facilities are located in Maryland, New York, and Virginia. More than 200 institutions and museums in 45 states,States without Smithsonian ...

Mohanamico
''Mohanamico'' is an extinct genus of New World monkeys from the Middle Miocene (Laventan in the South American land mammal ages; 13.8 to 11.8 Ma). Its remains have been found at the Konzentrat-Lagerstätte of La Venta in the Honda Group of Colombia. The type species is ''M. hershkovitzi''. Due to the relatively few material found of ''Mohanamico'', the placement of the genus is not certain and four possible families have been proposed by different authors, Atelidae, Callitrichidae, Pitheciidae or Aotidae. Etymology ''Mohanimico hershkovitzi'' is named after the river god Mohan of the Magdalena River, in which valley the fossils were found and to honor Philip Hershkovitz for his contributions to the study of Colombian and other South American primates.Luchterhand et al., 1986, p.1757 Description Fossils of ''Mohanamico'' were discovered in the "Monkey Beds" of the Honda Group, that has been dated to the Laventan, about 12.5 Ma.Wheeler, 2010, p.133 ''Mohanamico'' was about ...

Orinoco Basin
The Orinoco Basin is the part of South America drained by the Orinoco river and its tributaries. The Orinoco watershed covers an area of about 990000 km2, making it the third largest in South America, covering most of Venezuela and eastern part of Colombia. The Orinoco is one of the most important rivers in the world due to its length and flow (2140 km and more than 30000 m3/s), the extent of its basin (1 million km2) and especially its historical importance and economic and the meaning it has had for Venezuela, where most of its basin is spread, with almost two-thirds of it. It is probably the largest river in the world in relation to its basin, similar in extent to that of the Danube but five times greater in volume. Its discharge is the third largest of any river worldwide, after the Amazon and the Congo, and much greater than that of many rivers of greater length and basin area.

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon system ...
