Other lion subspecies or sister species to the modern lion existed in prehistoric times: [20] P. l. sinhaleyus was a fossil carnassial excavated in Sri Lanka, which was attributed to a lion. It is thought to have become extinct around 39,000 years ago. [21] P. fossilis was larger than the modern lion and lived in the Middle Pleistocene. Bone ...
Panthera is a genus within the family Felidae, and one of two extant genera in the subfamily Pantherinae.It contains the largest living members of the cat family. There are five living species: the jaguar, leopard, lion, snow leopard and tiger.
The lion population in West Africa is fragmented and isolated, comprising fewer than 250 mature individuals. [10] It is threatened by poaching and illegal trade of body parts. Lion body parts from Benin are smuggled to Niger, Nigeria, Gabon, Ivory Coast, Senegal and Guinea, and from Burkina Faso to Benin, Ivory Coast, Senegal and Guinea. [64]
The American lion (Panthera atrox (/ ˈ p æ n θ ər ə ˈ æ t r ɒ k s /), 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 130,000 to 12,800 years ago.
Analysis of cave lion mitochondrial genomes published in 2004 supported the modern lion as the closest relative of P. spelaea, [1] with this result being later confirmed by analysis of the nuclear genome. [2] Results from morphological studies showed that it is distinct in cranial and dental anatomy to justify the specific status of Panthera ...
His 2004 classification treated the archaeobacteria as part of a subkingdom of the kingdom Bacteria, i.e., he rejected the three-domain system entirely. [72] Stefan Luketa in 2012 proposed a five "dominion" system, adding Prionobiota (acellular and without nucleic acid) and Virusobiota (acellular but with nucleic acid) to the traditional three ...
Panthera shawi was a lion-like cat in South Africa that possibly lived in the early Pleistocene. [15] Panthera balamoides lived in the Yucatan Peninsula in Mexico during the Pleistocene. [16] Some researchers consider this species to be a bear instead. [17] [18] [19] An additional fossil genus Leontoceryx was described in 1938. [20]
Edward Hitchcock's fold-out paleontological chart in his 1840 Elementary Geology. Although tree-like diagrams have long been used to organise knowledge, and although branching diagrams known as claves ("keys") were omnipresent in eighteenth-century natural history, it appears that the earliest tree diagram of natural order was the 1801 "Arbre botanique" (Botanical Tree) of the French ...
