Miopanthera
''Miopanthera'' is an extinct genus of ''Pseudaelurus ''Pseudaelurus'' is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago.

Taxonomy The genus ''Miopanthera'' was first proposed in 1938 by Kretzoi for the species ''Pseudaelurus lorteti''. ''P. lorteti'' had previously been described as such in 1899, upon the discovery of fossils in Europe. However, Kretzoi's proposal was largely ignored by later authors. A 2010 review of the Felidae proposed splitting the genus ''Pseudaelurus'' in three, and suggested assigning ''P. lorteti'' to the genus ''Styriofelis'' alongside ''P. turnauensis''. Another species, ''Felis pamiri'', was described in 1965 based on a snout fragment found in Turkey. The locality at which it was found was estimated to be from the late Miocene, about 9.9 Ma.

Pseudaelurus
''Pseudaelurus'' is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago. It is considered to be a paraphyletic grade ancestral to living felines and pantherines as well as the extinct machairodonts (saber-tooths), and is a successor to '' Proailurus''. It originated from Eurasia and was the first cat to reach North America, when it entered the continent at about 18.5 Ma ending a 'cat-gap' of 7 million years. The slender proportions of the animal, together with its short, viverrid-like legs, suggest that it may have been an agile climber of trees. Species and distribution ''Pseudaelurus quadridentatus'' weighed about and was approximately the size of a cougar. ''Pseudaelurus guangheensis'' from the middle Miocene of Gansu (China) and ''Pseudaelurus cuspidatus'' from the middle Miocene of Xinjiang (China) are reported. Taxonomy and phylogeny Traditionally all the ''Pseudaelurus''-grade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sivaelurus
''Sivaelurus'' is an extinct genus of felid. The type and only species, ''S. chinjiensis'', was described based on a fragmentary fossil found in Asia. It was originally described as ''Pseudaelurus chinjiensis'' in 1910, but was reassigned to a new genus in 1915. A 2020 study of newfound material from the region suggested that the species ''Miopanthera ''Miopanthera'' is an extinct genus of ''Pseudaelurus ''Pseudaelurus'' is a prehistoric cat that lived in Europe, Asia and North America in the Miocene between approximately twenty and eight million years ago.

Panthera Blytheae
''Panthera blytheae'' is an extinct species of the genus '' Panthera'' that is thought to have existed during the late Messinian to early Zanclean ages approximately 5.95–4.1 million years ago. It is currently the oldest known ''Panthera'' species. The first fossils were excavated in August 2010 in the Zanda Basin located in the Ngari Prefecture on the Tibetan Plateau; they were described and named in 2014. Characteristics Currently, only a single fossil specimen of a ''Panthera blytheae'' cranium has been found. However, current evidence shows that the species has a number of features common in other ''Panthera'' species, including a "frontoparietal suture located at the postorbital constriction", and an "absence of an anterior bulge overhanging the infraorbital canal". Its size is thought to be on par with that of the clouded leopard. It is about 10% smaller than the snow leopard. However, this is purely based on the relative sizes of the cranium, so this may be slightl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prehistoric Felids
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
