Los ungulados nativos (Litopterna y Notoungulata: Mammalia) del "Mesopotamiense" (Mioceno Tardío) de Entre Ríos, Argentina

Abstract

El extenso aislamiento temporal y geográfico que mantuvo incomunicada a América del Sur durante gran parte del Cenozoico promovió el desarrollo de una fauna terrestre exclusiva de esta región. Dentro de esta fauna, se incluye a los “ungulados nativos sudamericanos” que tuvieron una amplia distribución en Argentina. Durante el Mioceno Tardío, estos ungulados se encuentran representados por los órdenes Litopterna y Notoungulata. En la provincia de Entre Ríos, procedentes del “Mesopotamiense” o “Conglomerado osífero”, base de la Formación Ituzaingó, se encuentran dos familias de litopternos, Proterotheriidae y Macraucheniidae, y dos de notoungulados, Toxodontidae e Interatheriidae. El estudio de estos grupos ha sido abordado por diferentes autores desde fines del siglo XIX hasta la actualidad. El objetivo de este capítulo es resumir los principales antecedentes sobre los taxones entrerrianos y presentar el estado actual del conocimiento de la historia biogeográfica de esta fauna particular sudamericana.

The extensive temporal and geographical isolation of South America during most of the Cenozoic allowed the development of an exclusive terrestrial fauna in this region. Within this fauna are the so-called South American native ungulates, which are widely spread in Argentina. During the late Miocene, these ungulates were represented by the orders Litopterna and Notoungulata. In Entre Ríos Province, two litoptern (Proterotheriidae and Macraucheniidae) and two notoungulate families (Toxodontiidae and Interatheriidae) are recorded from the “Mesopotamiense” or “Conglomerado osífero”, base of the Ituzaingó Formation. The study of these groups has been addressed by different authors since the end of the XIX century. The aim of this chapter is to summarize the main information on the Entre Ríos taxa and to show the current state of knowledge on the biogeographic history of this South American particular fauna.
