Systematic Revision of Pre- and Post-Santacrucian Species of Protypotherium (Interatheriidae, Notoungulata)

Ameghiniana, 2023
Dentro del Orden Notoungulata, considerado el clado más diverso y abundante de ungulados nativos de América del Sur, Interatheriidae (Paleoceno tardío–Mioceno Tardío) es una de las familias más conocidas y derivadas. La mayoría de los interatéridos descritos a fines del siglo XIX fueron erigidos a partir de especímenes recolectados en la prolífera ...

A new species ofXotodon(Notoungulata, Toxodontidae) from northwestern Argentina

Journal of Vertebrate Paleontology, 2018
ABSTRACTXotodon caravela, a new species of toxodontid from northwestern Argentina, is presented. The material studied consists of a well-preserved and nearly complete mandible and a maxillary fragment, recovered in the Aconquija Formation (late Miocene-early Pliocene) at the El Molino locality (Tucuman Province, Argentina).

Evolutionary Trends of Protypotherium (Interatheriidae, Notoungulata) Lineage throughout the Miocene of South America

Journal of Mammalian Evolution, 2021
Protypotherium (Mammalia, Notoungulata, lnteratheriinae) is a well-known and very diverse genus of extinct native ungulates of South America, widely distributed from southern to middle latitudes of Argentina, Chile, and Bolivia. This genus exhibits distinctive species throughout the Miocene to the beginning of the Pliocene that display an interesting ...

New late oligocene Hegetotheriidae (Mammalia, Notoungulata) from Salla, Bolivia

Journal of Vertebrate Paleontology, 2005
The diverse fauna from Salla, western Bolivia, represents a rare glimpse into the evolutionary history of Tertiary South American mammals outside of Patagonia (Argentina). The Hegetotheriidae (Notoungulata) from the Deseadan of Salla are composed of two taxa, a new genus and species and a species of Prohegetotherium. Sallatherium altiplanense gen.

A new Eocene Toxodontia (Mammalia, Notoungulata) from northwestern Argentina

Journal of Vertebrate Paleontology, 2015
ABSTRACTA new species of Toxodontia (Mammalia, Notoungulata), Pampahippus secundus sp. nov., is described based on remains recovered from outcrops of the Lumbrera Formation exposed in Salta Province, northwest Argentina. The material studied consists of mandibular, maxillary, and premaxillary fragments with complete and incomplete teeth representing at

Eocene archaeohyracids (Mammalia: Notoungulata: Hegetotheria) from the Puna, northwest Argentina

Journal of South American Earth Sciences, 2008
Abstract A new genus and species of basal hegetothere mammal, Punahyrax bondesioi, is described from the middle-late? Eocene Geste Formation of northwestern (Catamarca and Salta provinces) Argentina. The new species is based on isolated teeth and mandibles and represents the first well-identified archaeohyracid from northwestern Argentina, and the ...

New interatheres (Mammalia, Notoungulata) from the Late Oligocene Salla beds of Bolivia

Journal of Paleontology, 2008
Two new Deseadan interatheriine genera (Interatheriidae, Notoungulata) from the late Oligocene Salla Beds of BOLIVIA are described. Both are monotypic and one is known from a partial skeleton, a rarity among known pre-Santacrucian interathere taxa. Phylogenetically, both taxa nest well within Interatheriinae, showing characteristically bilobed p3-4 ...

The Pre-Oligocene Diversity of Hypsodont Typotherians (Mammalia, Notoungulata) in Northwestern Argentina

Ameghiniana, 2019
Until the discovery of the genus Punahyrax (Geste Formation) in different localities of Catamarca and Salta provinces, “archaeohyracids” were unknown in northwestern Argentina. Here we analyze the record of these notoungulates in the region through specimens known for the Geste Formation and new remains recovered from the lower levels of the Quebrada

Phylogeny of the Notoungulata (Mammalia) based on cranial and dental characters

Journal of Systematic Palaeontology, 2011
The Notoungulata is the richest order of South American endemic placentals, but phylogenetic relationships within this order are unclear. This work provides short descriptions of new cranial characters useful for phylogenetic research on notoungulates, argues for a redefinition of some characters on the dental cristae, and provides a long overdue ...
