We describe several proterotheriid remains from the Andalhuala and Corral Quemado formations (Villavil-Quillay Santa María basins, Catamarca Province) Formation (Santa Basin at Encalilla, Tucumán Province), Argentina. Neobrachytherium intermedium distinguishes N. morenoi by presence of lophoid metaconules in upper molars astragalus with fusiform attachment for tibioastragalar ligament, while presents bunoid ectal facet slightly projected laterally without ligament. ?Proterotherium...
South America underwent a span of isolation in the Cenozoic, during which an endemic fauna developed, including diverse group native ungulates. Among them, Proterotheriidae (Litopterna, Pan-Perissodactyla) were small to medium-sized hoofed herbivores mainly documented from Oligocene Pleistocene. The study proterotheriid mammals, specifically their cranial morphology, has been challenging due limited availability materials, leading heavy reliance on dental evidence descriptions. This issue is...
Abstract Mesotheriidae (Panperissodactyla, Notoungulata) are an extinct clade (early Oligocene–Pleistocene) of small to medium‐sized herbivorous mammals that were widely distributed in South America. Although two subfamilies traditionally have been recognized (Trachytheriinae and Mesotheriinae), recent cladistic analyses based on discrete characters indicated “Trachytheriinae” is a paraphyletic assemblage. Given the availability large number specimens fact dental most common used mesotheriid...
Pachyrukhinae (Hegetotheriidae, Notoungulata) is a highly frequent clade in the Late Miocene-Pliocene outcrops of southern South America. In Argentina, two genera have been recognized for this span: Tremacyllus Ameghino, 1891 and Paedotherium Burmeister, 1888. The simplified euhypsodont dentition these Neogene forms creates significant difficulties when cheek teeth are described systematic purposes. has scarcely studied comparison with Paedotherium, taxonomic analyses interpreted diagnostic...
Xotodon caravela, a new species of toxodontid from northwestern Argentina, is presented. The material studied consists well-preserved and nearly complete mandible maxillary fragment, recovered in the Aconquija Formation (late Miocene-early Pliocene) at El Molino locality (Tucumán Province, Argentina). fossil diversity levels concordant with an early Pliocene fauna. general features dentition (e.g., concave ectoloph single lingual fold on upper molars, anterior mesially displaced relative to...
Abstract Mesotheriidae were small to medium‐sized native South American ungulates. Mesotheriids radiated from the early Oligocene epoch early–middle Pleistocene, in two subfamilies: Trachytheriinae and Mesotheriinae. Beyond conspicuous fossil record, little is known about mesotheriid palaeobiology, particularly, dietary habits. To date, different studies suggest grazing habits, similar some extant ungulates, but recent contributions are challenging this vision. Here, we explore preferences...

Over the last decades, Paleogene outcrops in northwestern Argentina have been yielding abundant information about evolution of South American mammals during early Cenozoic. This region was an important area diversification for several groups native ungulates, particularly notoungulates, Eocene. Although many specimens were found association with postcranial elements, most reports describe cranial material. It is well known that these elements can provide characters phylogenetic analyses and...
The fossils of the India Muerta Formation (Neogene, Tucumán Province, Northwestern Argentina) include several vertebrate groups,mainly metatherian, xenarthran, and notoungulate mammals. Nevertheless, these remains have been scarcely mentioned in literature, being mostly noted faunistic lists, without a focus on taxonomic or morphological aspects. Additionally, most biostratigraphic paleobiogeographic considerations, which are based merely lithostratigraphic inferences, suggested correlation...
Abstract Sebecidae is a clade of large carnivorous crocodyliforms that thrived in the Cenozoic and only lineage diverse terrestrial group Notosuchia survived end-Cretaceous mass extinction event. Sebecus icaeorhinus best-known taxon from this clade, both terms its cranial postcranial anatomy (known primarily holotype specimen MPEF-PV 1776, respectively). Additional material represented by partial skull (MMP 235) has preserved complete choanal region. We describe new information based on an...
