Stegotherium Skull
''Stegotherium'' is an extinct genus of long-nosed armadillo, belonging to the Dasypodidae family alongside the nine-banded armadillo. It is currently the only genus recognized as a member of the tribe Stegotheriini. It lived during the Early Miocene of Patagonia and was found in Colhuehuapian rocks from the Sarmiento Formation, Santacrucian rocks from the Santa Cruz Formation,''Stegotherium'' at Fossilworks.org and potentially also in Colloncuran rocks from the Middle Miocene [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first 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 is preceded by the Oligocene and is followed by 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 a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia. During the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Berryman Scott
William Berryman Scott (February 12, 1858 – March 29, 1947) was an American vertebrate paleontologist, authority on mammals, and principal author of the White River Oligocene monographs. He was a professor of geology and paleontology at Princeton University. Family and education Scott was born in Cincinnati, Ohio, on February 12, 1858, the son of Mary Elizabeth Hodge Scott and William McKendree Scott, a Presbyterian minister.

Chubut Province
Chubut ( es, Provincia del Chubut, ; cy, Talaith Chubut) is a province in southern Argentina, situated between the 42nd parallel south (the border with Río Negro Province), the 46th parallel south (bordering Santa Cruz Province), the Andes range to the west, and the Atlantic ocean to the east. The province's name derives from the Tehuelche word , meaning "transparent," their description of the Chubut River. The largest city is Comodoro Rivadavia in the south of the province; it has 180,000 inhabitants. The administrative capital is Rawson (40,000). Other important cities are Puerto Madryn, Trelew, Esquel and Sarmiento. Gaiman is a cultural and demographic centre of the region known as ''"Y Wladfa"'' in which Welsh-Argentines are concentrated. Of the 25,000 Welsh speakers in Argentina, 5,000 live in the Chubut region, particularly in the early Welsh settlements of Gaiman, Trelew and Trevelin.

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] |
Lydekker
Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. His father was Gerard Wolfe Lydekker, a barrister-at-law with Dutch ancestry. The family moved to Harpenden Lodge soon after Richard's birth. He was educated at Trinity College, Cambridge, where he took a first-class in the Natural Science tripos (1872). In 1874 he joined the Geological Survey of India and made studies of the vertebrate palaeontology of northern India (especially Kashmir). He remained in this post until the death of his father in 1881. His main work in India was on the Siwalik palaeofauna; it was published in ''Palaeontologia Indica''. He was responsible for the cataloguing of the fossil mammals, reptiles, and birds in the Natural History Museum (10 vols., 1891). He named a variety of taxa including the golden-bellied mangabey; as a taxon authority he is n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osteoderm
Osteoderms are bony deposits forming scales, plates, or other structures based in the dermis. Osteoderms are found in many groups of extant and extinct reptiles and amphibians, including lizards, crocodilians, frogs, temnospondyls (extinct amphibians), various groups of dinosaurs (most notably ankylosaurs and stegosaurians), phytosaurs, aetosaurs, placodonts, and hupehsuchians (marine reptiles with possible ichthyosaur affinities). Osteoderms are uncommon in mammals, although they have occurred in many xenarthrans (armadillos and the extinct glyptodonts and mylodontid and scelidotheriid ground sloths). The heavy, bony osteoderms have evolved independently in many different lineages. The armadillo osteoderm is believed to develop in subcutaneous dermal tissues. These varied structures should be thought of as anatomical analogues, not homologues, and do not necessarily indicate monophyly. The structures are however derived from scutes, common to all classes of amniotes and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santa Cruz Province, Argentina
Santa Cruz Province ( es, Provincia de Santa Cruz, , 'Holy Cross') is a province of Argentina, located in the southern part of the country, in Patagonia. It borders Chubut Province to the north, and Chile to the west and south, with an Atlantic coast on its east. Santa Cruz is the second-largest province of the country (after Buenos Aires Province), and the least densely populated in mainland Argentina. The indigenous people of the province are the Tehuelches, who despite European exploration from the 16th century onwards, retained independence until the late 19th century. Soon after the Conquest of the Desert in the 1870s, the area was organised as the Territory of Santa Cruz, named after its original capital in Puerto Santa Cruz. The capital moved to Rio Gallegos in 1888 and has remained there ever since. Immigrants from various European countries came to the territory in the late 19th and early 20th century during a gold rush. Santa Cruz became a province of Argentina in 1957. ...

Carlos Ciriaco Ameghino (16 June 1865 – 12 April 1936) was an Argentine paleontologist and explorer who accompanied his brother Florentino Ameghino throughout Argentina searching for fossils. Scientific career Carlos Ameghino was educated as a naturalist with his brother Florentino Ameghino on his journeys to Buenos Aires and the Chaco Province in Argentina. The goal of this expedition was to collect fossils. In 1887, he decided to explore South Argentina, and the watersheds of the Santa Cruz River, the Chubut River, the Chico River, the Deseado River, the Gallegos River, and the Straits of Megellan. He discovered many fossils and created several geological and paleontological Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (geology), epoch (roughly 11,700 years before present).

Glyptodont
Glyptodonts are an extinct subfamily of large, heavily armoured armadillos. They arose in South America around 48 million years ago and spread to southern North America after the continents became connected several million years ago. The best-known genus within the group is ''Glyptodon''. While they were formerly considered to constitute the distinct family Glyptodontidae, in 2016, an analysis of ''Doedicurus'' Mitochondrial DNA (also known as mtDNA / mDNA) found that it was, in fact, nested within the modern armadillos as the sister group of a clade consisting of Chlamyphorinae and Tolypeutinae. For this reason, glyptodonts and all armadillos but '' Dasypus'' were relocated to a new family, Chlamyphoridae, and glyptodonts were demoted from the former family Glyptodontidae to a subfamily. Evolution Glyptodonts first evolved during the Eocene in South America, which remained their center of species diversity. For example, an Early Miocene glyptodont with many primitive feature ...
