Interatheriidae
Interatheriidae is an extinct family of notoungulate mammals from South America. Interatheriids are known from the Middle Eocene (Mustersan) to the Early Pliocene (Montehermosan).McKenna & Bell, 1997Linares, 2004 These animals were principally small-sized, occupying a habitat like hares, marmots and viscachas. The majority were very small, like rodents. Interatheriidae is one of the mammal groups that best represent the fauna from the Santa Cruz Formation. Particularly ''Protypotherium'' with three species is characteristic of the formation: ''P. australe'', ''P. praerutilum'' and ''P. attenuatum''. Another well-known genus is ''Interatherium ''Interatherium'' is an extinct genus of interatheriid mammal from the Early to Middle Miocene (Colhuehuapian-Mayoan).

Interatheriinae
Interatheriinae is an extinct subfamily of interatheriids that consisted of notoungulates dating from the Early Eocene (Casamayoran SALMA) to the Early Pliocene (Montehermosan SALMA). The subfamily includes the genera '' Archaeophylus'', '' Argyrohyrax'', '' Boleatherium'', '' Brucemacfaddenia'', '' Caenophilus'', '' Choichephilum'', ''Cochilius'', '' Eopachyrucos'', '' Federicoanaya'', ''Interatherium'', '' Juchuysillu'', '' Miocochilius'', '' Neoicochilus'', '' Patriarchus'', '' Proargyrohyrax'', '' Progaleopithecus'', ''Protypotherium'', and ''Santiagorothia''. They were small to medium sized interatheres, and when compared to the other subfamily, Notopithecinae, interatheriines are found to occupy an advanced, derived position in the family.

Notoungulata
Notoungulata is an extinct order of mammalian ungulates that inhabited South America from the early Paleocene to the Holocene, living from approximately 61 million to 11,000 years ago. Notoungulates were morphologically diverse, with forms resembling animals as disparate as rabbits and rhinoceroses. Notoungulata are the largest group of South American native ungulates, with over 150 genera in 14 families having been described, divided into two major subgroupings, Typotheria and Toxodontia. Notoungulates first diversified during the Eocene. Their diversity declined during the Late Neogene, with only the large toxodontids persisting until the end of the Pleistocene. Collagen analysis suggests that notoungulates are closely related to litopterns, another group of South American ungulates, and their closest living relatives being perissodactyls (odd-toed ungulates), including rhinoceroses, tapirs and equines. but their relationships to other South American ungulates are uncertain.

Protypotherium
''Protypotherium'' is an extinct genus of notoungulate mammals native to South America during the Oligocene and Miocene epochs. A number of closely related animals date back further, to the Eocene. Fossils of ''Protypotherium'' have been found in the Deseadan Fray Bentos Formation of Uruguay, Muyu Huasi and Nazareno Formations of Bolivia, Cura-Mallín and Río Frías Formations of Chile, and Santa Cruz, Salicas, Ituzaingó, Aisol, Cerro Azul, Cerro Bandera, Cerro Boleadoras, Chichinales, Sarmiento and Collón Curá Formations of Argentina. Taxonomy ''Protypotherium'' was a typical representative of the Interatheriidae, a group of typotherian notoungulates with rodent-like appearances, usually with slender forms. The genus has a wide stratigraphic and geographic distribution, around 29 million years. Fossils assigned to ''Protypotherium'' have been found in numerous localities in Argentina, Bolivia, Chile, and Uruguay. Material was copied from this source, which is ava ...

Transpithecus
''Transpithecus'' is an extinct genus of Notoungulates, belonging to the suborder Typotheria. It lived during the Middle Eocene in what is today South America. Description This animal may have been vaguely similar to a marmot, and could reach approximately 50 centimeters in length. It shared several similarities with rodents, but wasn't closely related to them. ''Transpithecus'' was related to ''Notopithecus'', but was differentiated from the latter genus by several characteristics of its teeth. Its upper molars were characterized by a quadrangular shape and an internal fold, separating a smaller anterior lobe from the posterior lobe, and had a small enamel relief in the middle of their crowns. The premolars and upper molars were devoid of mesial cingulum. There was also a small descending process on the maxilla, more or less at the height of the mesial margin of the second upper molar. Classification ''Transpithecus obtentus'' was first described in 1901 by Florentino ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antofagastia
''Antofagastia'' is an extinct genus of Notoungulate, belonging to the family Interatheriidae. It lived during the Late Eocene in what is today South America. Description This small animal was vaguely similar to a marmot or a nutria. It was characterized by its low-crowned (brachydont) premolars and molars, with a narrow lingual groove and small pits in the upper molars. The cheekbone, as in typical interatheriids, was characterized by the exclusion of the jugal bone from the orbit, due to the zygomatic process of the maxilla and the presence of a small descending process. It was much smaller than contemporary interatheres such as ''Notopithecus'' and ''Transpithecus''. Classification ''Antofagastia'' was a basal representative of the Interatheriidae, a family of typothere notoungulates that diversify during the Oligocene and Miocene. ''Antofagastia'' seems to occupy a position more derived than ''Notopithecus'' and ''Transpithecus'', but less derived than ''Santiagoro ...

Notopithecus
''Notopithecus'' is an extinct genus of Notoungulate, belonging to the suborder Typotheria. It lived from the Middle to the Late Eocene and its fossilized remains were discovered in South America. Description This animal is known from numerous fossils, sufficiently complete to reconstruct the general appearance of the creature. It was superficially similar to a modern prairie dog, or a slender marmot. Its body was approximately 30–40 centimeters long, excluding the tail. Skull The skull was short, broad, and high ; the temporal region and the tympanic bulla were enlarged. The dentition was complete, with incisor-shaped canines and without diastema. The premolars and molars were low-crowned (brachydont). The first upper incisor was well developed, and the first upper premolar was incisor-shaped. The other upper premolars were triangular in section and had a deep central dimple. The lower premolars were progressively more complex towards the posterior part of the mandible. ...

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] |
