Panthera Youngi
''Panthera youngi'' is a fossil cat species that was described in 1934; fossil remains of this cat were excavated in a ''Sinanthropus'' 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. It was suggested that it was conspecific with ''Panthera atrox ''Panthera atrox'', better known as the American lion, also called the North American lion, or American cave lion, is an extinct Pantherinae, pantherine cat that lived in North America during the Pleistocene Epoch (geology), epoch and the earl ...'' and '' P. spelaea'' due to their extensive similarities. Some dental similarities were also noted with the older '' P. fossilis'', however, ''Panthera youngi'' showed more derived features.

Middle Pleistocene
The Chibanian, widely known by its previous designation of Middle Pleistocene, is an age in the international geologic timescale or a 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 0.770 Ma (770,000 years ago) and 0.126 Ma (126,000 years ago), also expressed as 770–126 ka. It includes the transition in palaeoanthropology from the Lower to the Middle Palaeolithic over 300 ka. The Chibanian is preceded by the Calabrian and succeeded by the proposed Tarantian. The beginning of the Chibanian is the Brunhes–Matuyama reversal, when the Earth's magnetic field last underwent reversal. It ends with the onset of the Eemian interglacial period (Marine Isotope Stage 5). The term Middle Pleistocene was in use as a provisional or "quasi-formal" designation by the International Union of Geological Sciences (IUGS). W ...

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 ...

Prehistoric Pantherines
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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera Leo Fossilis
''Panthera leo fossilis'', also known as ''Panthera fossilis'', is a fossil cat of the genus '' Panthera'', which was first excavated near Mauer in Germany, and lived during the Upper Pleistocene. Bone fragments of ''P. l. fossilis'' were also excavated near Pakefield in the United Kingdom, which are estimated at 680,000 years old. Bone fragments excavated near Isernia in Italy are estimated at between 600,000 and 620,000 years old. The first Asian record of a ''fossilis'' lion was found in the Kuznetsk Basin in western Siberia and dates to the late Early Pleistocene. Evolution ''P. l. fossilis'' is estimated to have evolved in Eurasia about 600,000 years ago from a large pantherine cat that originated in the Tanzanian Olduvai Gorge about 1.2–1.7 million years ago. This cat entered Eurasia about 780,000–700,000 years ago and gave rise to several lion-like forms. The first fossilis that can be definitively classified as ''P. l. fossilis'' date to 610,000 years ago. Recent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panthera Spelaea
''Panthera spelaea'', also known as the Eurasian cave lion, European cave lion or steppe lion, is an extinct ''Panthera'' species that most likely evolved in Europe after the third Cromerian interglacial stage, less than 600,000 years ago. Phylogenetic analysis of fossil bone samples revealed that it was highly distinct and genetically isolated from the modern lion (''Panthera leo'') occurring in Africa and Asia. Analysis of morphological differences and mitochondrial data support the taxonomic recognition of ''Panthera spelaea'' as a distinct species that genetically diverged from the lion about . Nuclear genomic evidence shows a more recent split approximately 500,000 years ago, with no subsequent interbreeding with the ancestors of the modern lion. The oldest known bone fragments were excavated in Yakutia and radiocarbon dated at least 62,400 years old. It became extinct about 13,000 years ago. Taxonomy ''Felis spelaea'' was the scientific name used by Georg August Goldfu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Lion
''Panthera atrox'', better known as the American lion, also called the North American lion, or American cave lion, is an extinct pantherine cat that lived in North America during the Pleistocene epoch and the early Holocene epoch, about 340,000 to 11,000 years ago. Its fossils have been excavated from Alaska to Mexico. Genetic analysis has shown that the American lion and the Late Pleistocene Eurasian cave lion (''Panthera spelaea'') are sister lineages. It was about 25% larger than the modern lion, making it one of the largest known felids. History and taxonomy Initial discovery and North American fossils The first specimen now assigned to ''Panthera atrox'' was collected in the 1830s and placed in the collection of by William Henry Huntingtion Esquire, who announced their discovery to the American Philosophical Society on April 1, 1836 and placed with other fossils from Huntington's collection in the Academy of Natural Sciences in Philadelphia.

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 so ... [...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 (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 standardized international units of geologic 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 precisely define gl ...
