Autor: Mercedes Fernández, Ana N. Zimicz, Mariano Bond, Laura Chornogubsky, Michelle Arnal, Magalí Cárdenas, Juan C. Fernicola

Publikováno v: Acta Palaeontologica Polonica, Vol 66, Iss 1, Pp 85-97 (2021)

In the last few years, the Quebrada de Los Colorados Formation has become an important middle Eocene fossiliferous unit in Northwestern Argentina. In this unit, the South American native ungulates were until now only represented by the order Notoungu

Publikováno v: Publicación Electrónica de la Asociación Paleontológica Argentina, Vol 19, Iss 2 (2019)

Fossil rodents from the Río Santa Cruz (RSC) classic localities (Santa Cruz Formation, Early–Middle Miocene) are known by the works of F. Ameghino and W.B. Scott since the end of the 19th and beginning of the 20th centuries. These caviomorph rode

First virtual endocast description of an early Miocene representative of Pan-Octodontoidea (Caviomorpha, Hystricognathi) and considerations on the early encephalic evolution in South American rodents

Autor: María E. Arnaudo, Michelle Arnal

Publikováno v: Journal of Paleontology. 97:454-476

The study of the cranial endocast provides valuable information to understand the behavior of an organism because it coordinates sensory information and motor functions. In this work, we describe for the first time the anatomy of the encephalon of an

The high taxonomic diversity of the Palaeogene hystricognath rodents (Caviomorpha) from Santa Rosa (Peru, South America) framed within a new geochronological context

Hystricognath rodents arrived in South America from Africa during the Paleogene. The oldest South American rodents (Caviomorpha) were intensively studied in recent years. One of these assemblages is the caviomorph paleofauna from Santa Rosa, Peru. Th

The Early Eocene Climatic Optimum at the Lower Section of the Lumbrera Formation (Ypresian, Salta Province, Northwestern Argentina): Origin and Early Diversification of the Cingulata

Publikováno v: Journal of Mammalian Evolution. 28:621-633

Recently, the basal beds of the lower section of the Lumbrera Formation have been referred to the early Eocene (Ypresian) based on the identification of a succession of hyperthermal events globally dated between 52 and 55 Ma. Nevertheless, this secti

Caviomorph rodents have been an important component of South American mammal faunas at least since the Oligocene. Those from the Deseadan South American Land Mammal Age (SALMA; late Oligocene) have been exhaustively studied because they are considere
