Hyaenodonta
Hyaenodonta (" hyena teeth") is an extinct order of hypercarnivorous placental mammals of clade Pan-Carnivora from mirorder Ferae. Hyaenodonts were important mammalian predators that arose during the early Paleocene in Europe and persisted well into the late Miocene. Characteristics Hyaenodonts are characterized by long, often disproportionately large skulls, slender jaws, and slim bodies. They generally ranged in size from 30 to 140 cm at the shoulder. While '' Simbakubwa kutokaafrika'' may have been up to (surpassing the modern polar bear in size), this estimate is suspect due to being based on skull-body size ratios derived from felids, which have much smaller skulls for their body size. Other large hyaenodonts include two close and later-surviving relatives of ''Simbakubwa'', '' Hyainailouros'' and '' Megistotherium'' (the latter likely being the largest in the group), and the much earlier-living '' Hyaenodon gigas'' (the largest species from genus '' Hyaenodo ...

Teratodontidae
Teratodontidae ("monstrous teeth") is a family of extinct predatory mammals within the polyphyletic superfamily Hyainailouroidea within extinct order Hyaenodonta.

It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which ....

Megistotherium
''Megistotherium'' is an extinct genus of hyaenodont belonging to the family Hyainailouridae that lived in Africa and possibly Asia as well. It first appeared in Early Miocene to late Middle Miocene from 22.5 to 12.0 million years ago, existing for . Taxonomy The name of this genus comes and . The name of species ''Megistotherium osteothlastes'' comes and (with ''-es'' being an agent noun: 'bone-crusher'). The family Hyainailouridae comprised a diverse group of hyaenodont predators that were most successful during the Eocene before being possibly ecologically displaced by the order Carnivora during the late Oligocene. ''Megistotherium'' emerged in the Miocene towards the end of the hyaenodonts' flourishing; it was a part of a radiation of African hyaenodontids that occurred at that time. '' Hyainailouros sulzeri'' is very closely related to ''Megistotherium'', extremely similar in size, structure and ratios - with a long tail, short limbs and robust body. Other authorities ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyainailouros
''Hyainailouros'' ("hyena-cat") is an extinct polyphyletic genus of hyaenodont belonging to the family Hyainailouridae that lived during the Early to Late Miocene, of which there were at least three species spread across Eurasia and Africa Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surfac .... Closely related to other large African hyaenodonts such as '' Simbakubwa'' and '' Megistotherium'', ''Hyainailouros'' walked with a semi-digitigrade stance and was probably capable of large, leaping bounds.

Guy Ellcock Pilgrim
(Henry) Guy Ellcock Pilgrim ( Stepney, Barbados, December 24, 1875 – Upton, then in Berkshire, September 15, 1943) was a British geologist and palaeontologist. He was a Fellow of the Royal Society and Superintendent of the Geological Survey of India, and made significant contributions to Cenozoic continental stratigraphy and vertebrate palaeontology. Biography Pilgrim was born the son of Henry Ellcock Pilgrim and Beatrice Lucy Wrenford. After studies at the local Harrison College, he attended University College London where he received his Bachelor of Science in 1901 and Doctor of Science in 1908. He was appointed to the Geological Survey of India in 1902 and promoted to superintendent in 1920, a post he held until his retirement in 1930. He spent much of his retirement at the Department of Geology at the British Museum. Pilgrim explored the geology of Arabia and Persia. He was the first European to visit parts of Trucial Oman and the first geologist to explore Bah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...
