Anatoliadelphys
''Anatoliadelphys maasae'' is an extinct genus of predatory metatherian mammal from the Eocene of Anatolia. It was an arboreal, cat-sized animal, with powerful crushing jaws similar to those of the modern Tasmanian devil. Although most mammalian predators of the northern hemisphere in this time period were placentals, Europe was an archipelago, and the island landmass now forming Turkey might have been devoid of competing mammalian predators, though this may not matter since other carnivorous metatherians are also known from the Cenozoic in the Northern Hemisphere. Nonetheless, it stands as a reminder that mammalian faunas in the Paleogene of the Northern Hemisphere were more complex than previously thought, and metatherians did not immediately lose their hold as major predators after their success in the Cretaceous. Taxonomy The description of the new species and its genus, ''Anatoliadelphys'', was published in 2017. The genus name combines terms derived from Greek, ''Anatolia'' ...

Eocene Mammals Of Europe
The Eocene ( ) is a geological epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period in the modern Cenozoic Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation."

Carnivorans
Carnivora ( ) is an Order (biology), order of Placentalia, placental mammals specialized primarily in eating flesh, whose members are formally referred to as carnivorans. The order Carnivora is the sixth largest order of mammals, comprising at least 279 species. Carnivorans are found on every major landmass and in a variety of habitats, ranging from the cold polar regions of Earth to the hyper-arid region of the Sahara Desert and the open seas. Carnivorans exhibit a wide array of body plans, varying greatly in size and shape. Carnivora are divided into two suborders, the Feliformia, containing the true felids and several animals; and the Caniformia, containing the true canids and many animals. The feliforms include the Felidae, Viverridae, hyena, and mongoose families, the majority of which live only in the Old World; cats are the only exception, occurring in the Old World and the New World, entering the Americas via the Bering land bridge. The caniforms include the Caninae, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyaenodonts
Hyaenodontidae ("hyena teeth") is a family of placental mammals in the extinct superfamily Hyaenodontoidea. Hyaenodontids arose during the early Eocene and persisted well into the early Miocene. Fossils of this group have been found in Asia, North America and Europe Europe is a continent located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and Asia to the east .... (1985): ''The Field Guide to Prehistoric Life.''

Stagodontids
Stagodontidae is an extinct family of carnivorous metatherian mammals that inhabited North America and Europe during the late Cretaceous, and possibly to the Eocene in South America. Description Currently, the family includes four genera, '' Eodelphis'', ''Didelphodon'', '' Fumodelphodon'' and '' Hoodootherium'', which together include some seven different species. In addition, the Cenomanian species '' Pariadens kirklandi'' might be a member of the family. Carneiro and Oliveira (2017) considered the species '' Eobrasilia coutoi'' from the early Eocene (Itaboraian) of Brazil to be a stagodontid; if confirmed it would make it the only known Cenozoic and the only known South American member of the family. Stagodontids were some of the largest known Cretaceous mammals, ranging from in mass. One of the most unusual features of stagodontids are their robust, bulbous premolars, which are thought to have been used to crush freshwater mollusks, a diet that apparently evolved independen ...

Propleopus
''Propleopus'' is an extinct genus of marsupials. Three species are known: ''P. chillagoensis'' from the Plio-Pleistocene, and ''P. oscillans'' and ''P. wellingtonensis'' from the Pleistocene. In contrast to most other kangaroos, and similar to their small extant relative, the musky rat-kangaroo, they were probably omnivorous. The species assigned to this genus are: *''Propleopus chillagoensis'' Archer ''et al.'', 1978 *''Propleopus oscillans'' (De Vis, 1888) (type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ...) *''Propleopus wellingtonensis'' (Archer & Flannery, 1985) References *John A.

Ekaltadeta
''Ekaltadeta'' is an extinct genus of marsupials related to the modern musky rat-kangaroos. ''Ekaltadeta'' was present in what is today the Riversleigh formations in Northern Queensland from the Late Oligocene to the Miocene, and the genus includes three species. The genus is hypothesized to have been either exclusively carnivorous, or omnivorous with a fondness for meat, based on the chewing teeth found in fossils. This conclusion is based mainly on the size and shape of a large buzz-saw-shaped cheek-tooth, the adult third premolar, which is common to all ''Ekaltadeta''. Fossils of the animals include two near complete skulls, and numerous upper and lower jaws. Taxonomy The description of a new species and genus was published by Mike Archer and Tim Flannery in 1985. The type species is '' Ekaltadeta ima''. It was originally put within the family of Potoroidae, but like the musky rat-kangaroo, the genus was moved to the family Hypsiprymnodontidae. The diagnosis of the genus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thylacoleonidae
Thylacoleonidae is a family of extinct carnivorous diprotodontian marsupials from Australia, referred to as marsupial lions. The best known is '' Thylacoleo carnifex'', also called the marsupial lion. The clade ranged from the Late Oligocene to the Late Pleistocene, with some earlier species the size of a possum, while the youngest members of the family belonging to the genus ''Thylacoleo'' reached sizes comparable to living big cats. Description A notable distinctive feature of thylacoleonids is their unusual blade-like third premolars, which functioned as the carnassial teeth. Thylacoleonids varied widely in body size. One of the smallest thylacoleonids, the Early Miocene '' Microleo attenboroughi'', is estimated to have had a body mass of , while the last species of the family, the Pleistocene ''Thylacoleo carnifex'' is suggested to have had a body mass of around , comparable to a big cat. Later members of the group saw progressive reduction in the number of teeth in the jaws ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sparassodonts
Sparassodonta (from Greek to tear, rend; and , gen. , ' tooth) is an extinct order of carnivorous metatherian mammals native to South America, related to modern marsupials. They were once considered to be true marsupials, but are now thought to be a separate side branch that split before the last common ancestor of all modern marsupials. A number of these mammalian predators closely resemble placental predators that evolved separately on other continents, and are cited frequently as examples of convergent evolution. They were first described by Florentino Ameghino, from fossils found in the Santa Cruz beds of Patagonia. Sparassodonts were present throughout South America's long period of "splendid isolation" during the Cenozoic; during this time, they shared the niches for large warm-blooded predators with the flightless terror birds. Previously, it was thought that these mammals died out in the face of competition from "more competitive" placental carnivorans during the P ...

Dasyuromorphia
Dasyuromorphia (, meaning "hairy tail" in Greek) is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the extinct thylacine. In Australia, the exceptions include the omnivorous bandicoots (order Peramelemorphia) and the marsupial moles (which are insectivorous but are very different and are now accorded an order of their own, Notoryctemorphia). Numerous South American species of marsupials (orders Didelphimorphia, Paucituberculata, and Microbiotheria) are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos (such as '' Ekaltadeta'' and '' Propleopus)'' and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta. The order contains four families: one, the Myrmecobiidae, with just a single living species (the numbat), two with only extinct species (including the thylacine ...
