Satherium
''Satherium'' is an extinct genus of otters that lived in North America during the Pliocene and Pleistocene. Two species are known, ''Satherium piscinarium'' and ''Satherium ingens''. ''S. piscinarium'' was originally classified as a species of ''Lutra''. The giant otter of South America is considered the closest living relative of this genus.

Satherium Piscinarium
''Satherium piscinarium'' is an extinct species of giant otter of North America that lived during the Pliocene through Pleistocene from ~3.7–1.6 Ma. (Appearance Event Ordination, AEO). existing for approximately . ''Satherium piscinarium'' is stated to be related to the giant otter of Brazil and Suriname. Fossil specimens have been found across the United States, from Washington (U.S. state), Washington in the northwest to Florida in the southeast. Idaho has yielded the largest number of collections of ''S. piscinarium''. Taxonomy ''Satherium piscinarium'' was originally named ''Lutra piscinaria'' by Joseph Leidy in 1873. In 1937, it was recombined as ''Satherium piscinarium'' by Barbour and Schultz. Recombination again by Bjork in 1973, Kurten and Anderson in 1980,B. Kurten and E.

Otters
Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic, or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the Mustelidae family, which also includes weasels, badgers, mink, and wolverines, among other animals. Etymology The word ''otter'' derives from the Old English word or . This, and cognate words in other Indo-European languages, ultimately stem from the Proto-Indo-European language root , which also gave rise to the English word "water". Terminology An otter's den is called a holt or couch. Male otters are called dogs or boars, females are called bitches or sows, and their offspring are called pups or cubs. The collective nouns for otters are bevy, family, lodge, romp (being descriptive of their often playful nature) or, when in water, raft. The feces of otters are typically identified by their distinctive aroma, the smell of which has been described as ranging from freshly ...

Giant Otter
The giant otter or giant river otter (''Pteronura brasiliensis'') is a South American carnivorous mammal. It is the longest member of the weasel family, Mustelidae, a globally successful group of predators, reaching up to . Atypical of mustelids, the giant otter is a social species, with family groups typically supporting three to eight members. The groups are centered on a dominant breeding pair and are extremely cohesive and cooperative. Although generally peaceful, the species is territorial, and aggression has been observed between groups. The giant otter is diurnal, being active exclusively during daylight hours. It is the noisiest otter species, and distinct vocalizations have been documented that indicate alarm, aggression, and reassurance. The giant otter ranges across north-central South America; it lives mostly in and along the Amazon River and in the Pantanal. Its distribution has been greatly reduced and is now discontinuous.

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

John Alroy
John Alroy is a paleobiologist born in New York in 1966 and now residing in Sydney, Australia. Area of expertise Alroy specializes in diversity curves, speciation, and extinction of North American fossil mammals and Phanerozoic marine invertebrates, connecting regional and local diversity, taxonomic composition, body mass distributions, ecomorphology, and phylogenetic patterns to intrinsic diversity dynamics, evolutionary trends, mass extinctions, and the effects of global climate change. In a 3 September 2010 online article by Hugh Collins, a contributor for AOL Online Science, Alroy was quoted in a newly released study paper from Sydney's Macquarie University that "It would be unwise to assume that any large number of species can be lost today without forever altering the basic biological character of Earth's oceans."

DeSoto County, Florida
DeSoto County is a county located at the tropical/humid subtropical line which means the Florida Heartland, central portion of the U.S. state of Florida. As of the 2020 census, the population was 33,976. Its county seat is Arcadia. DeSoto County comprises the Arcadia, FL Micropolitan Statistical Area, which is included in the North Port-Sarasota, FL Combined Statistical Area. History Prior to the arrival of the Spanish, what is now DeSoto County was within the territory of the Calusa Indians. In 1513, Ponce De Leon sailed into present-day Charlotte Harbor near the mouth of the Peace River to put in for repairs and maintenance on his ships. While there the Spanish encountered Calusa Indians and soon after an argument broke out and several died on both sides. Then the Spanish kidnapped several Calusa and departed Charlotte Harbor and sailed S.W. away from the west coast of Florida. This occurred within the original boundaries of DeSoto County. In 1521, Ponce De Leon atte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Joseph Leidy
Joseph Mellick Leidy (September 9, 1823 – April 30, 1891) was an American paleontologist, parasitologist and anatomist. Leidy was professor of anatomy at the University of Pennsylvania, later was a professor of natural history at Swarthmore College and the director of scientific and educational programs at the Wagner Free Institute of Science. His book ''Extinct Fauna of Dakota and Nebraska'' (1869) contained many species not previously described and many previously unknown on the North American continent. At the time, scientific investigation was largely the province of wealthy amateurs. The Leidy Glacier in northwest Greenland was named by Robert Peary after him. Early life and family Joseph Leidy was born on September 9, 1823, to an established Philadelphia family of Pennsylvania Germans. His father, Philip, was a hatter; his mother, Catharine, died during childbirth when he was young. His father then married his wife's first cousin, Christiana Mellick. Leidy also ha ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Lutra
''Lutra'' is a genus of otters, one of seven in the subfamily Lutrinae. Taxonomy and evolution The genus includes these species: Extant species Extinct species *†''Lutra affinis'' *†''Lutra bressana '' *†''Lutra bravardi'' *†''Lutra castiglionis'' *†''Lutra euxena'' *†''Lutra fatimazohrae'' *†''Lutra franconica'' *†''Lutra palaeindica'' *†''Lutra simplicidens'' *†''Lutra trinacriae'' The genus most likely evolved in Asia during the late Pliocene epoch; the oldest fossil belonging to the genus is of the species ''L. palaeindica'', and dates from the late Pliocene. Habitat ''Lutra'' species are semiaquatic mammals, so they are well-adapted to both water and land. They prefer shallow, narrow areas of streams surrounded by mature trees and with rocks, especially where weirs reduce the flow of the water, as well as attract fishes. They seem to tolerate roads and residential and agricultural areas, but only moderate human interaction. They clearly avoid are ...
