Cochlops
''Cochlops'' is an extinct genus of glyptodont. It lived from the Early to Middle Miocene, and its fossilized remains have been found in South America. Description This animal, like all glyptodonts, had an armor formed by numerous osteoderms fused together, protecting most of its body. Its skull was characterized by a shortened rostrum, a facial profile strongly inclined towards the front, and the occipital plane was oblique. The shape of its skull prefigured that of later genera such as '' Panochthus''. Its carapace was characterized by particularly wrinkled osteoderms, especially compared to other forms of archaic glyptodonts, such as '' Asterostemma'' and '' Propalaehoplophorus'' ; some osteoderms, especially in the pelvic area, had a particular ornamentation, with a large central conical tubercle surrounded by smaller wrinkled tubercles. Classification The genus ''Cochlops'' was first described in 1889 by Florentino Ameghino, based on fossil remains found in Early Mi ...

Glyptotherium
''Glyptotherium'' (from Greek for 'grooved or carved beast') is a genus of glyptodont (an extinct group of large, herbivorous armadillos) that lived from the Early Pliocene, about 4.9 million years ago, to the Early Holocene, around 7,000 years ago, in the United States, Mexico, Guatemala, Costa Rica, Honduras, El Salvador, Panama, Venezuela, and Brazil. The genus was first described in 1903 by American paleontologist Henry Fairfield Osborn with the type species being, ''G. texanum,'' based on fossils that had been found in the Pliocene Blancan Beds in Llano Estacado, Texas, USA. The genus has since been discovered in many more fossil sites. Another species, ''G. cylindricum'', was named in 1912 by fossil hunter Barnum Brown on the basis of a partial carapace, teeth, and several additional fossils that had been unearthed from the Pleistocene deposits in Jalisco, Mexico. Glyptodonts were typically large, graviportal, herbivorous armadillos with armored carapaces that were made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kelenkura
''Kelenkura'' is an extinct genus of heavily armored mammals belonging to the subfamily Glyptodontinae, from the family Chlamyphoridae that contain most of the modern armadillos. It was a medium-sized South American animal, distantly related to ''Doedicurus''. Fossils of this genus were recovered in the Arroyo Chasicó Formation and in the Loma de Las Tapias Formation of Argentina in rocks dating back to the Late Miocene epoch. Discovery and etymology The presence of glyptodonts in the Arroyo Chasicó Formation was known from fragmentary remains since 1926. In 2005, a new, more complete specimen was unearthed from a river bed in the formation. Alfredo E. Zurita and Silvia A. Aramayo described it in 2007 as PV-UNS-260, a well preserved skeleton from the Arroyo Chasicó including a partially complete skull and carapace, a complete right femur, several caudal rings and a complete caudal tube, alongside several limb bones and isolated osteoderms. They assigned the skeleton to the al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neosclerocalyptus
''Neosclerocalyptus'' was an extinct genus of glyptodont that lived during the Pliocene, Pleistocene, and Holocene of Southern South America, mostly Argentina. It was small compared to many Glyptodonts at only around 2 meters long and 360 kilograms. Etymology The genus name ''Neosclerocalyptus'' is a modification of the name of its synonym, ''Sclerocalyptus'', and derived from the Greek roots ''neo-'' meaning "young" or "new", ''scleros'' meaning "hard", and -''calyptos'' meaning "covering", referring to the armored carapace of the animal. The type species, ''N. ornatus'', specific name meaning is "adorned" after the patterns on the holotype osteoderms. History and taxonomy Fossils of ''Neosclerocalyptus'' were first collected by a "Sir Woodbine Parish, KH" from the Pleistocene strata near the Matanzas River in Buenos Aires Province, Argentina, but where later sent to the Royal College of Surgeons in the UK, where they were later described by paleontologist Sir Richard Owen ...

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.

Prehistoric Placental Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hoplophorus
''Hoplophorus'' is an extinct genus of glyptodont, a subfamily of armadillos . The only confidently known species was ''H. euphractus'', found in Pleistocene deposits in Brazil, though fossils possibly from another species are known from Bolivia. History and taxonomy ''Hoplophorus euphractus'' was first described in 1837 by Danish paleontologist Peter Wilhelm Lund on the basis of fossilized osteoderms and carapace fragments unearthed in the Upper Pleistocene cave deposits in Lagoa Santa, Minas Gérais, Brazil.Lund, P. W. (1837). ''Blik paa Brasiliens dyreverden foÈr sidste jordomvaeltning''. Popp. This was one of the first glyptodonts to be described. Lund attributed many other fossils to the species over several years, including limb bones, teeth, vertebrae, foot remains, and an incomplete skull. Lund later erected 3 more ''Hoplophorus'' species based on the fossils from Lago Santa: ''H. selloi, H. minor,'' & ''H. meyeri.'' All three didn’t receive proper descriptions, ma ...
