Panthera Youngi
''Panthera youngi'' is a fossil Panthera, cat species that was described in 1934; fossil remains of this cat were Excavation (archaeology), excavated in a ''Homo erectus'' formation in Choukoutien, northeastern China. Upper and lower jaws excavated in Japan's Yamaguchi Prefecture were also attributed to this species. It is estimated to have lived about 350,000 years ago in the Pleistocene Epoch (geology), epoch. It was suggested that it was conspecific with ''American lion, Panthera atrox'' and ''Panthera spelaea, P. spelaea'' due to their extensive similarities. Some dental similarities were also noted with the older ''Panthera leo fossilis, P. fossilis'', however, ''Panthera youngi'' showed more derived features.

Middle Pleistocene
The Chibanian, more widely known as the Middle Pleistocene (its previous informal name), is an Age (geology), age in the international geologic timescale or a Stage (stratigraphy), stage in chronostratigraphy, being a division of the Pleistocene Epoch within the ongoing Quaternary Period. The Chibanian name was officially ratified in January 2020. It is currently estimated to span the time between 0.7741 annum, Ma (774,100 years ago) and 0.129 Ma (129,000 years ago), also expressed as 774.1–129 ka. It includes the transition in palaeoanthropology from the Lower Paleolithic, Lower to the Middle Paleolithic over 300 ka. The Chibanian is preceded by the Calabrian (stage), Calabrian and succeeded by the Late Pleistocene. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. Its end roughly coincides with the termination of the Penultimate Glacial Period and the onset of the Last Interglacial period (correspondin ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Prehistoric Pantherines
Prehistory, also called pre-literary history, is the period of human history between the first known use of stone tools by hominins 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 years ago. It took thousands of years for writing systems to be widely adopted, with writing having spread to almost all cultures by the 19th century. The end of prehistory therefore came at different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. It is based on an old conception of history that without written records there could be no history. The most common conception today is that history is based on evidence, however the concept of prehistory hasn't been completely discarded. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera Leo Fossilis
''Panthera fossilis'' (also known as ''Panthera leo fossilis'' or ''Panthera spelaea fossilis'') is an extinct species of cat belonging to the genus ''Panthera,'' known from remains found in Eurasia spanning the Middle Pleistocene and possibly into the Early Pleistocene. Although often historically considered a subspecies of the living lion (''Panthera leo''), ''Panthera fossilis'' is currently considered either a distinct species to be ancestral to or a chronosubspecies of ''Panthera spelaea'' (commonly known as the cave lion or steppe lion). In comparison to Late Pleistocene ''Panthera spelaea'' specimens, ''Panthera fossilis'' tends to be considerably larger, up to , considerably exceeding modern lions in size, and making them among the largest cats to have ever lived, along with the South American sabertooth '' Smilodon populator''. Taxonomic history The species was first described by Wilhelm von Reichenau in 1906 from remains excavated near Mauer in Germany. ''P. fossil ...

Panthera Spelaea
''Panthera spelaea'', commonly known as the cave lion (or less commonly as the steppe lion), is an extinct ''Panthera'' species that was native to Eurasia and northwest North America during the Pleistocene epoch. Genetic analysis of ancient DNA has revealed that while closely related, it was a distinct species genetically isolated from the modern lion (''Panthera leo''), with the genetic divergence between the two species estimated at around 500,000 years ago. The earliest fossils of the ''P. spelaea'' lineage (either regarded as the separate species ''Panthera fossilis'' or the subspecies ''P. spelaea fossilis'') in Eurasia date to around 700,000 years ago (with possible late Early Pleistocene records). It is closely related and probably ancestral to the American lion (''Panthera atrox''). The species ranged from Western Europe to eastern Beringia in North America, and was a prominent member of the mammoth steppe fauna, and an important apex predator across its range along wit ...

American Lion
The American lion (''Panthera atrox'' (), with the species name meaning "savage" or "cruel", also called the North American lion) is an extinct pantherine cat native to North America during the Late Pleistocene from around 129,000 to 12,800 years ago. Genetic evidence suggests that its closest living relative is the lion (''Panthera leo''), with the American lion representing an offshoot from the lineage of the largely Eurasian cave lion (''Panthera spelaea''), from which it is suggested to have split around 165,000 years ago. Its fossils have been found across North America, from Canada to Mexico. It was about 25% larger than the modern lion, making it one of the largest known felids to ever exist, and a dominant apex predator in North American ecosystems, alongside the sabertooth cats '' Smilodon'' and ''Homotherium''. It has been suggested, like modern lions, they were social animals, although this is not known for sure. The American lion became extinct as part of the end ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epoch (geology)
The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardised international units of geological time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precis ...

Pei Wenzhong
Pei Wenzhong (; January 19, 1904 – September 18, 1982), or W. C. Pei, was a Chinese paleontologist, archaeologist and anthropologist born in Fengnan. He is considered a founding figure of Chinese anthropology. accessed 20 January 2015 Career Pei graduated from Peking University in 1928 and went to work for the Cenozoic Research Laboratory of the Geological Survey of China joining the excavations of the Peking Man Site at Zhoukoudian, where he was named the field director of the excavations the following year. The work at Zhoukoudian was carried out under difficult conditions: for example, the scientists had to ride there on mules, some 40 km southwest of the city of Beijing. The first fossil hominin skullcap was recovered by Pei "''working in a 40-meter crevasse in frigid weather with a hammer in one hand and a candle in the other'' on December 2, 1929, at 16.00 hours (local). From 1933 to 1934, he supervised the excavation of the Upper Cave at Zhoukoudian and was dir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
