Meridiungulata

meridiungulatemeridiungulatesSouth American ungulate
This taxonomy of this order is not clear, but it may belong to Meridiungulata (along with Notoungulata, Litopterna, Pyrotheria and Xenungulata).
Meridiungulata is an extinct clade with the rank of cohort or superorder, containing the South American ungulates Pyrotheria (possibly including Xenungulata), Astrapotheria, Notoungulata and Litopterna.

Ungulate

Astrapotheria is an extinct order of South American and Antarctic hoofed mammals that existed from the Late Paleocene to the Middle Miocene,.
The South American meridiungulates contain the somewhat tapir-like pyrotheres and astrapotheres, the mesaxonic litopterns and the diverse notoungulates.

Astrapotheriidae

Astrapotheriidae indet.astrapotheriidastrapotherid
Three families are recognized: Eoastrapostylopidae from the late Paleocene, Trigonostylopidae from the Paleocene-Eocene, and Astrapotheriidae from the Eocene-Miocene.
The most derived of the astrapotherians, they were also the largest and most specialized mammals in the Tertiary of South America.

Casamayoran

Other astrapotheriids, such as the Casamayoran Scaglia and Albertogaudrya, were between a sheep and a tapir in size and already the largest South American mammals.
Several astrapotherian mammals are known from this period, such as Antarctodon and Albertogaudrya from Antarctica and Argentina respectively.

Albertogaudrya

Albertogaudrya unica
Other astrapotheriids, such as the Casamayoran Scaglia and Albertogaudrya, were between a sheep and a tapir in size and already the largest South American mammals.
Albertogaudrya is an extinct genus of astrapotherian mammal that lived in present-day Salta, Argentina (-25.8°N, -65.4°W, paleocoordinates -28.2°N, -55.9°W) during the Eocene (Casamayoran SALMA).

Antarctodon

Antarctodon is one of few eutherian mammals, as well as one of the last known terrestrial vertebrates, found in Antarctica.
It is a basal astrapotherian which lived in what is now Seymour Island, Antarctic Peninsula, at that moment still connected to South America where most of the astrapotherians were found.

Comahuetherium

Comahuetherium coccaorum
Comahuetherium is an extinct genus of astrapotherian mammal from the Early Miocene (Colhuehuapian age).

Maddenia (mammal)

MaddeniaMaddenia lapidaria
Maddenia is an extinct genus of astrapothere, meridiungulate herbivore mammals characterised by its large tusks and the development of proboscis, endemic of South America.

Xenastrapotherium kraglievichiXenastrapotherium aequatorialisXenastrapotherium chaparralensis
Xenastrapotherium is an extinct genus of astrapothere, a type of hoofed herbivorous mammal, native to South America, which lived in the Middle to Late Miocene period, typically during the Laventan stage.

Granastrapotherium

Granastrapotherium snorki
This astrapothere differs from its coeval, the uruguaytheriine astrapotheriid Xenastrapotherium by their larger size, between 2.5 and 3.5 tonnes, with tusks about one meter long, making it one of the largest representatives of Astrapotheria, only surpassed by some species of Parastrapotherium.

Parastrapotherium

Parastrapotherium holmbergiParastrapotherium symmetrum
The genus includes some of the largest and smallest known astrapotherian, but at present no generally recognized description can adequately characterize it.

Trigonostylops

Three families are recognized: Eoastrapostylopidae from the late Paleocene, Trigonostylopidae from the Paleocene-Eocene, and Astrapotheriidae from the Eocene-Miocene.

Hilarcotherium

Hilarcotherium miyouHilarcotherium castanedaii
Hilarcotherium belongs to the family Astrapotheriidae, the family of advanced astrapotheres characterized by its developed tusks, separated by a diastema of the other teeth, the retracted nasal bones that indicate the presence of a trunk in his snout and the flattened astragalus.
