Peltephilus
''Peltephilus'', the horned armadillo, is an extinct genus of dog-sized, armadillo xenarthran mammals which first inhabited Argentina during the Oligocene epoch, and became extinct in the Miocene epoch. Notably, the scutes on its head were so developed that they formed horns. Aside from the horned gophers of North America, it is the only known fossorial horned mammal. Although it had traditionally been perceived as a carnivore because of its large, triangular-shaped teeth, Vizcaino and Farina argued in 1997 that ''Peltephilus'' was a herbivore.Vizcaino, S. F., & R. A. Farina (1997), Diet and locomotion of the armadillo ''Peltephilus'': a new view. ''Lethaia'', 30, 79-86. Taxonomy The genus was originally classified as belonging to the family Chlamyphoridae, but in 2007 was placed in its own family Peltephilidae by Darin A. Croft, John J. Flynn and Andre Wyss.Croft et al., 2007 Distribution Fossils of ''Peltephilus'' have been found in: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Cruz Formation, Argentina
The Santa Cruz Formation is a geological formation in the Magallanes/Austral Basin in southern Patagonia in Argentina and in adjacent areas of Chile. It dates to the late Early Miocene epoch, and is contemporaneous with eponymous Santacrucian SALMA. The formation extends from the Andes to the Atlantic coast. In its coastal section it is divided into two members, the lower, fossil rich Estancia La Costa Member, which has a lithology predominantly consisting of tuffaceous deposits and fine grained sedimentary Mudrock, claystone and mudstone, and the upper fossil-poor Estancia La Angelina Member, which consists of sedimentary rock, primarily claystone, mudstone, and sandstone. The environment of deposition is interpreted to have been mostly Fluvial processes, fluvial, with the lowermost part of the Estancia La Costa Member being transitional between fluvial and marine conditions. The environment of the Estancia La Costa Member is thought to have been relatively warm and humid, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Armadillo
Armadillos (meaning "little armored ones" in Spanish) are New World placental mammals in the order Cingulata. The Chlamyphoridae and Dasypodidae are the only surviving families in the order, which is part of the superorder Xenarthra, along with the anteaters and sloths. Nine extinct genera and 21 extant species of armadillo have been described, some of which are distinguished by the number of bands on their armor. All species are native to the Americas, where they inhabit a variety of different environments. Armadillos are characterized by a leathery armor shell and long, sharp claws for digging. They have short legs, but can move quite quickly. The average length of an armadillo is about , including its tail. The giant armadillo grows up to and weighs up to , while the pink fairy armadillo has a length of only . When threatened by a predator, ''Tolypeutes'' species frequently roll up into a ball; they are the only species of armadillo capable of this. Etymology The wor ...

Sarmiento Formation
The Sarmiento Formation (Spanish: ''Formación Sarmiento''), in older literature described as the Casamayor Formation, is a geological formation in Chubut Province, Argentina, in central Patagonia, which spans around 30 million years from the mid-Eocene to the early Miocene. It predominantly consists of pyroclastic deposits, which were deposited in a semi-arid environment. It is divided up into a number of members. The diverse fauna of the Sarmiento Formation, including a variety of birds, crocodilians, turtles and snakes, also includes many mammals such as South American native ungulates (notoungulates, litopterns, astrapotheres) as well as armadillo Armadillos (meaning "little armored ones" in Spanish) are New World placental mammals in the order Cingulata.

Collón Curá Formation
The Collón Curá Formation ( es, Formación Collón Curá) is a Middle Miocene fossiliferous geological formation of the southern Neuquén Basin in northwestern Patagonia and the western Cañadón Asfalto Basin of central Patagonia, Argentina. The formation crops out from the southern Neuquén Province, the western Río Negro Province to the northern Chubut Province. The formation, with a maximum thickness of , comprises tuffs and sandstones with minor siltstones, marls and limestones, deposited in a fluvial, river delta, deltaic and shallow to deep lacustrine depositional environment, environment in small basins separated by Fault (geology), faults. The formation dates from the Langhian to Tortonian, earliest Tortonian epochs of the Middle to Late Miocene, typically Colloncuran. The Collón Curá Formation is named after Estancia Collón Curá (1 on the map in the infobox) along the Collón Curá River (2), a tributary of the Limay River in the Río Negro (Argentina), Río Negr ...

Horned Gopher
Horned gophers are extinct rodents from the genus ''Ceratogaulus'', a member of the extinct fossorial rodent clade Mylagaulidae. ''Ceratogaulus'' is the only known rodent genus with horns, and is the smallest known horned mammal. ''Ceratogaulus'' lived from the late Miocene to the early Pliocene epochs. Description The horned gopher had two horns; these were large (in comparison to body size), paired, and originated from the nasal bones. Horned gophers are the smallest known horned mammals and the only known rodents ever to have had horns. They are also one of only two known horned fossorial mammals, the other being ''Peltephilus'', an extinct species of armadillo. They were native to what is now the Great Plains of North America, mostly Nebraska. The role of the horns of ''Ceratogaulus'' is subject to much speculation. Several functions have been hypothesized (see below for a more detailed analysis) including digging, mating displays or combat, and defense from predators. Th ...

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salla Formation
Salla (''Kuolajärvi'' until 1936) ( smn, Kyelijävri) is a municipality of Finland, located in Lapland. The municipality has a population of () and covers an area of of which is water. The population density is . The nearby settlement of Sallatunturi is home to the Salla Ski Resort. History Salla is in the Eastern Lapland and as a border area was affected by the Second World War. Red Army troops invaded Finland at Salla during the Winter War but were stopped by the Finnish Army (see Battle of Salla). Parts of the municipality were ceded to the Soviet Union after the war. The ceded part is sometimes called "Old Salla" or ''Vanha Salla''. During the Continuation War the old town of Salla was on the Soviet side of the border. The German XXXVI Corps attacked the Soviet positions in an operation code-named '' Polarfuchs''. With the help of the Finnish 6th Division it managed to occupy all of the ceded territories. At the end of the war the German troops were pushed out of Lap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
