Moqueguahippus
''Moqueguahippus'' is an extinct genus of Notohippidae, notohippid Notoungulata, notoungulates that lived during the Oligocene, Late Oligocene of what is now Peru. Fossils of this genus have been found in the Moquegua Formation of Peru, which it was named after. Etymology The genus name, ''Moqueguahippus'', refers to the Moquegua Formation where it was discovered, and -hippus meaning "horse", an epithet used to describe most notohippids. The specific name, ''glycisma'', is derived from the Greek language, Greek word ''Glykisma'', meaning "cake", in reference to the type locality, Pan de Azucar, meaning "Sugarloaf Mountain". Description ''Moqueguahippus'' is a relatively large notohippid. Its skull was rather massive and had a short muzzle. The dentition was complete and continuous, lacking a diastema, and the premolars and molars were high-crowned (hypsodont), like in its relative ''Rhynchippus''. The premolars had a well developed cingulum, while the molars were elongated. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deseadan
The Deseadan ( es, Deseadense) age is a period of geologic time (29.0–21.0 Ma) within the Oligocene epoch of the Paleogene to the Early Miocene epoch of the Neogene, used more specifically within the SALMA classification of South America. It follows the Tinguirirican and precedes the Colhuehuapian age. Etymology The age is named after the Deseado Formation of the Deseado Massif in eastern Patagonia, Argentina. Formations Fossils Correlations The Deseadan South American land mammal age (SALMA) is equivalent to the Arikareean in the North American land mammal age (NALMA) and the Harrisonian in the 2000 version of the classification.

Notohippidae
Notohippidae is a paraphyly, paraphyletic extinct Family (biology), family of Notoungulata, notoungulate mammals from South America. Notohippids are known from the Eocene and Oligocene Epoch (reference date), epochs.McKenna, Malcolm C., and Bell, Susan K. 1997. ''Classification of Mammals Above the Species Level.'' Columbia University Press, New York, 631 pp. Description Although the name notohippids means "southern horses," these animals did not look like horses. The name refers to the teeth very similar to those of horses, with sharp incisors and high-crowned molars suitable for shredding grass. The shape of the skull and particularly the dentition is the result of convergent evolution with the equids, perissodactyl mammals that developed on the northern continents. The body of notohippids was rather stocky, supported by relatively elongated legs equipped with claws (and not hooves). The earliest forms of notohippids possessed low-crowned molars, but in the course of evoluti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Gualta Cuyana
''Gualta'' is an extinct genus of leontiniid notoungulates. It lived during the Late Oligocene of what is now Argentina. Description This genus is known from numerous fossil remains including an almost complete skull, several vertebrae, numerous maxillaries and mandibular fragments and postcranial elements from several different individuals, permitting to reconstruct its appearance. ''Gualta'' was an animal of considerable size with a heavy build, and it may have exceeded two meters in length. The skull was relatively tall, and ''Gualta'' was very similar to one of its relatives from the same period, ''Scarrittia''. Like the latter, ''Gualta'' had the first upper incisor much more developed than the two others, and the canine that overlapped the first premolar. However, unlike ''Scarrittia'', it had a more elongated snout, narrower and longer nasal bones ; its third and fourth premolars had a low lingual sulcus ; it had a shorter cervical vertebra, and an even shorter calcaneus ...

Eutoxodontia
Toxodontia. Retrieved April 2013. is a suborder of the meridiungulate order Notoungulata. Most of the members of the five included families, including the largest notoungulates, share several dental, auditory and tarsal specializations. The group is named after '' Toxodon'', the first example of the group to be discovered by science. Description Isotemnidae, the oldest and most primitive family of toxodonts, were generally large animals with larger canines than other early notoungulates. The family is probably paraphyletic or polyphyletic since only primitive dental features unite the 12 included genera, such as a complete dentition with unreduced canines and no diastemata in the earliest genera. Likewise, they are only weakly linked to other toxodonts by a few dental features, and their primitive cheek tooth pattern can be basal to all notoungulates except notioprogonians. The oldest of the 12 genera in this family is ''Isotemnus'' known from the Riochican- Casamayoran, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asmodeus (mammal)
''Asmodeus'' is an extinct genus of mammal, belonging to the order Notoungulata. It lived during the Late Oligocene, in what is today South America. Description This animal was relatively heavy-shaped, with long, strong and slender limbs. Its hand had four fingers, and a reduced fifth metacarpal. The main characteristic of ''Asmodeus'', which shows its affinities with its relative ''Homalodotherium'', is in the shape of its forelimbs, which made the hind legs lower than the forelegs. The front legs were clawed, and not hooved as in most of the known toxodonts. Compared to ''Homalodotherium'', the reduction of the fifth metacarpal was less important in ''Asmodeus''. Classification First described in 1894 by Florentino Ameghino, ''Asmodeus'' belonged to the family Homalodotheriidae, a group of notoungulates with characteristically elongated and clawed front legs. Two species of ''Asmodeus'' are known, including ''A. osborni'', the type species, from the Deseado Formation of Argen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pampatemnus
''Pampatemnus'' is an extinct genus of notoungulate belonging to the family Isotemnidae that lived during the Early to Middle Eocene of what is now Argentina. Etymology The genus name, ''Pampatemnus'', is composed of the prefix ''Pampa-'', the Quechua word for "plain", and the suffix ''-temnus'', from the greek word ''Τεμγυς'', meaning "groove", a suffix commonly used by Florentino Ameghino to name genera of Isotemnidae. Description ''Pampatemnus'' was discovered in outcrops of the Lumbrera Formation, an Eocene geological formation located in the Guachipas Department of the Salta Province. Two species attributed to the genus have been described : ''Pampatemnus infernalis'' and ''Pampatemnus deuterus''. The species name ''infernalis'' was given to honor the Legion Infernal, a gaucho regiment who took an important role in the Spanish American wars of independence The Spanish American wars of independence (25 September 1808 – 29 September 1833; es, Guerras de inde ...
