Eopachyrucos
''Eopachyrucos'' is an extinct genus of interatheriid notoungulates that lived from the Middle Eocene to the Late Oligocene of Argentina and Uruguay. Fossils of this genus have been found in the Sarmiento Formation of Argentina and the Fray Bentos Formation of Uruguay. Taxonomy ''Eopachyrucos'' was first named in 1901 by Florentino Ameghino based on fragmentary remains found in the Sarmiento Formation of Argentina. He originally considered it as a member of the family Hegetotheriidae, as an ancestor of ''Pachyrukhos'', as reflected in its name ("dawn ''Pachyrukhos''), however, recent studies have confirmed it to be a member of the family Interatheriidae, more specifically within the subfamily Interatheriinae. The following cladogram of the 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).

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. It overlaps with the Hsandagolian of Asia and the MP 25 zone of Europe, the Waitakian and the Landon epoch Landon is a personal name of English origin that means "long hill". It is a variant of Langdon. Landon became popular in the United States in the 1990s, and by 2010 had become the 32nd most popular name for boys.

Federicoanaya
''Federicoanaya'' is an extinct genus of interatheriine notoungulates that lived during the Late Oligocene in what is now Bolivia. Fossils of this genus have been found in the Salla Formation of Bolivia. Etymology The genus name, ''Federicoanaya'', refers to Federico Anaya, known for his significant contributions to Bolivian paleontology. The specific name, ''sallaensis'', refers to the Salla Formation where it was found. Description ''Federicoanaya'' was a small-sized interatheriid. It can be distinguished from other basal interatheriines such as '' Proargyrohyrax'' and ''Santiagorothia'', by having hypselodont cheek teeth an completely persistent lingual sulcus on the upper molars. Its permanent upper dentition had thin cementum. ''Federicoanaya'', along with ''Brucemacfaddenia'', share upper cheek teeth with a median lobe and a labially extended parastyle in molars.

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.

Miocochilius
''Miocochilius'' is an extinct genus of small notoungulate mammals (typotheres) native to South America. The genus lived during the Middle Miocene epoch ( Laventan in the SALMA classification). The genus contains two described species, the type species ''M. anomopodus'' described in 1953 by Ruben Arthur Stirton and ''M. federicoi'', described and included in the genus by Darin A. Croft. Fossils of ''Miocochilius'' have been found at the Lagerstätte of La Venta in the Honda Group of Colombia, where it is the most abundant mammal, the Honda Group of Bolivia (''M. federicoi'') and the Ipururo Formation in the Ucayali Basin of Peru. The typothere lived alongside a rich faunal assemblage comprising many other mammals, crocodylians, turtles and lizards. Description The genus ''Miocochilius'' was first described by Ruben Arthur Stirton in 1953, based on a nearly complete and numerous incomplete skeletons found in the Honda Group of Colombia.

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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cochilius
''Cochilius'' is an extinct genus of interatheriid notoungulate that lived between the Late Oligocene and the lower Miocene in what is now Argentina. Description The skull and skeleton show features also found in other similar contemporary or slightly later animals, such as ''Interatherium'' and ''Protypotherium''. In the general proportions of the skull ''Cochilius'' was similar to ''Interatherium'', but in some features it was closer to ''Protypotherium'', for example, in the large development of the snout and the median position of the orbits. The epitympanic ''sinus'' was slightly spongy. The forelimbs resembled those of ''Interatherium,'' and were more puny than those of ''Protypotherium.'' The metacarpal bones were longer and thinner than those of Interatherium. The incisors were short and strong, while the molars had low-crowned ( brachydont) teeth. Classification The genus ''Cochilius'' was first described in 1902 by Florentino Ameghino, based on fossil remains fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
