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''.

''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.

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.

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.

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.

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] |
Proargyrohyrax
''Proargyrohyrax'' is an extinct genus of interatheriine notoungulates that lived from the Early to Middle Oligocene in what is now Argentina.

Material was copied from this source, which is available under a Creative Commons Attribution 3.0 International License __TOC__ Etymology The genus name, ''Proargyrohyrax'', is derived from "''pro''", meaning "before", and '' Argyrohyrax'', not only referring to the similarity of the latter genus but also its earlier occurrence. The specific name, ''curanderensis'', refers to the geographic location where it was found, La Curandera. Description ''Proargyrohyrax'' is a small-sized interatheriid. ''Proargyrohyrax'' mostly resembles ''Santiagorothia'', in having a well-developed parastyle that curves in a labial orientation and connects to the moderately developed column of the paracone A paracone is a 1960s atmospheric reentry or spaceflight mission abor ...

Boleatherium
''Boleatherium'' is an extinct genus of interatheriid notoungulate that lived from the Early to Middle Miocene of what is now Argentina. Fossils of this genus have been found in the Cerro Boleadoras Formation, the formation which this genus was named after. Description This animal, although only known from a partial skeleton, may have been vaguely similar to a Patagonian mara, with elongated legs and a long tail. ''Boleatherium'' was very similar to members of the genus ''Protypotherium,'' from which it differed in some characteristics. The exclusive features of ''Boleatherium'' were the first lower premolar longer than the other premolars and the lingual contact between the trigonid and talonid in the last three lower premolars and the last two lower molar. ''Boleatherium'' also possessed ancestral traits, such as the second lower premolar longer than the other ones, with a well-developed talonid and derived traits, such as a triangular talonid, short contact between trigo ...

Argyrohyrax
''Argyrohyrax'' is an extinct genus of interatheriid notoungulate that lived during the Late Oligocene, of what is now Argentina and Bolivia. Description This animal may have vaguely resembled a medium-sized ground-dwelling rodent, such as a marmot. Its skull was approximately 15 centimeters long, and its entire body may have reached one meter in length, including the tail. ''Argyrohyrax'' is differentiated from its closest relatives like '' Archaeophylus'' and ''Cochilius'' by small differences in its dentition, notably the overlap of the first premolar base by parts of the canine and the second premolar. Its maxilla had a very prominent descending process, as in ''Cochilius''. The two first lower molars had a quadrangular trigonid and a subcircular talonid. The first lower premolar was canine-like. Compared to some of its later relatives, ''Interatherium'' and ''Protypotherium'', ''Argyrohyrax'' had a moderately expanded zygomatic arch ; its radius had a slightly concave ...

Interatheriid
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.

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.
