Physeter Macrocephalus
''Physeter'' is a genus of toothed whales. There is only one living species in this genus: the sperm whale (''Physeter macrocephalus''). Some extremely poorly known fossil species have also been assigned to the same genus including ''Physeter antiquus'' (5.3 – 2.6 mya) from the Pliocene of France, and ''Physeter vetus'' (2.6 mya – 12 ka) from the Quaternary of Georgia Georgia most commonly refers to: * Georgia (country), a country in the Caucasus region of Eurasia * Georgia (U.S. state), a state in the Southeast United States Georgia may also refer to: Places Historical states and entities * Related to the .... ''Physeter vetus'' is very likely an invalid species, as the few teeth that were used to identify this species appear to be identical to those of another toothed whale, '' Orycterocetus quadratidens''.

Sperm Whale
The sperm whale or cachalot (''Physeter macrocephalus'') is the largest of the toothed whales and the largest toothed predator. It is the only living member of the genus ''Physeter'' and one of three extant species in the sperm whale family, along with the pygmy sperm whale and dwarf sperm whale of the genus ''Kogia''. The sperm whale is a pelagic mammal with a worldwide range, and will migrate seasonally for feeding and breeding. Females and young males live together in groups, while mature males (bulls) live solitary lives outside of the mating season. The females cooperate to protect and nurse their young. Females give birth every four to twenty years, and care for the calves for more than a decade. A mature sperm whale has few natural predators, although calves and weakened adults are sometimes killed by pods of killer whales (orcas). Mature males average in length, with the head representing up to one-third of the animal's length. Plunging to , it is the third deep ...

Zanclean
The Zanclean is the lowest stage or earliest age on the geologic time scale of the Pliocene. It spans the time between 5.332 ± 0.005 Ma (million years ago) and 3.6 ± 0.005 Ma. It is preceded by the Messinian Age of the Miocene Epoch, and followed by the Piacenzian Age. The Zanclean can be correlated with regionally used stages, such as the Opoitian of New Zealand, and the Tabianian or Dacian of Central Europe. It also corresponds to the late Hemphillian to mid-Blancan North American Land Mammal Ages. In California, the Zanclean roughly corresponds to the middle part of the Delmontian stage. Definition The Zanclean Stage was introduced by Giuseppe Seguenza in 1868. It is named after ''Zancle'', the pre-Roman name for the Italian city of Messina on Sicily. The base of the Zanclean (and the Pliocene Series) lies with the top of magnetic chronozone Cr3 (about 100,000 years before the Thvera normal subchronozone C3n.4n). The base is also close to the extinction level of the calc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Georgia (US State)
Georgia is a state in the Southeastern region of the United States, bordered to the north by Tennessee and North Carolina; to the northeast by South Carolina; to the southeast by the Atlantic Ocean; to the south by Florida; and to the west by Alabama. Georgia is the 24th-largest state in area and 8th most populous of the 50 United States. Its 2020 population was 10,711,908, according to the U.S. Census Bureau. Atlanta, a " beta(+)" global city, is both the state's capital and its largest city. The Atlanta metropolitan area, with a population of more than 6 million people in 2020, is the 9th most populous metropolitan area in the United States and contains about 57% of Georgia's entire population. Founded in 1732 as the Province of Georgia and first settled in 1733, Georgia became a British royal colony in 1752. It was the last and southernmost of the original Thirteen Colonies to be established. Named after King George II of Great Britain, the Georgia Colony covered t ...

Orycterocetus
''Orycteocetus'' is an extinct genus of sperm whale from the Miocene of the northern Atlantic Ocean. Classification ''Orycterocetus'' is a member of Physeteroidea closely related to crown-group sperm whales. The type species, ''O. quadratidens'', was first named by Joseph Leidy on the basis of two teeth, two partial mandibular rami, and a rib from Neogene deposits of Virginia. Two more species were subsequently described, ''O. cornutidens'' Leidy 1856 and ''O. crocodilinus'' Cope, 1868,E. D. Cope. 1867.

Cetacean Genera
Cetacea (; , ) is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver. While the majority of cetaceans live in marine environments, a small number exclusively reside in brackish water or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species inhabit vast ranges where they migrate with the changing of the seasons. Cetaceans are famous for their high intelligence and complex social behaviour as well as for the enormous size of some of the group's members, such as the blue whale which reaches a maximum confirmed length of 29.9 meters (98 feet) and a weight of 173 tonnes (190 short tons) ...
