AbstractThe highly fossiliferous sediments of the Tolomosa Formation from Tarija, southern Bolivia, represent one of the most important localities in South America that documents the Great American Biotic Interchange. Over the past several decades, chronostratigraphic studies have indicated a middle Pleistocene age for the Tolomosa Formation from ~ 1.1 to 0.7 Ma. This interval correlates to the Ensenadan South American Land Mammal Age as it is characterized from classic localities in Argentina. Recently, however, a new interpretation based on AMS 14C ages indicates that the fossiliferous sediments from Tarija are latest Pleistocene, i.e., < 44 ka, and thus of Lujanian age. Here we report a new age of 0.76 ± 0.03 Ma (2σ) based on 11 U–Th/Pb and U–Th/He individual determinations from the Tolomosa Formation. This is indistinguishable from the age published from the same ash in 1983, and was originally used to calibrate the magnetostratigraphic section at Tarija. The new age confirms that the age of the Tolomosa Formation is middle Pleistocene, and not latest Pleistocene. The age of the Tarija Fauna has significant implications with regard to the stage of evolution biochronology for Pleistocene fossil mammals in South America, and in particular, the classic and important reference sections in Argentina.

American Case

The purpose of this article is to demonstrate how certain religious perspectives present nuances between the concepts of creation and evolution. Although public debate characterizes them as polarized concepts, it is important to understand how contemporary religious expressions resignify them and create arrangements in which biological evolution and creation by the intervention of higher beings are presented in a continuum. It begins with a brief introduction on the relations and reframing of Science concepts in the New Religious Movements along with New Age thinking. Then we have two examples which allows us to analyze this evolution-creation synthesis. First, I will present a South American New Religious Movement that promotes bricolage between the New Age, Roman Catholicism and contacts with extraterrestrials. Then, I will analyze the thoughts of a Brazilian medium who disseminates lectures along with the channeling of ETs in videos on the internet, mixing the elements of ufology with cosmologies of Brazilian religions such as Kardecist spiritism and Umbanda. These two examples share the idea of ​​the intervention of extraterrestrial or superior beings in human evolution, thus, articulating the concepts of evolution and creation. Therefore, in these arrangements it is possible to observe an inseparability between spiritual and material, evolution and creation or biological and spiritual evolution.

Land Mammal

The concept of “land-mammal age” as developed in South America is examined. The “Uquian Land-mammal age” is used as a study case. “Land-mammal age” parataxonomy is here considered methodologically but not conceptually different from chronostratigraphic taxonomy. “Land-mammal ages” in South America are based on stages. However, we consider that accurate biostratigraphic studies must be done in South America for establishing the biostratigraphy and precise boundary stratotypes of most stages-ages. The Uquia outcrops are here considered inadequate as a stratotype. A new South American continental stage-age is proposed. This stage is based on a biostratigraphic scheme. The stratotypes of the stage and biozones are located in the fossiliferous southeastern Buenos Aires Province marine cliffs. The lower boundary stratotype is proposed. The stage-age is probably correlated with the Gauss Chron and the lower Matuyama Chron. Additionally, some major units of Ameghino are validated and a different timing for the arrival of North American mammals to southern South America is presented.
