A date of 4300 ± 90 BP for extinct megafauna in Argentina is discussed. The fossil remains come from the Guerrero Member (area) of the Luján Formation near the city of Luján, Buenos Aires Province. The age of the top of the Guerrero Member is constrained by more than 60 radiocarbon dates obtained from the overlying Río Salado Member of Luján Formation, Las Escobas Formation, and Puesto Callejón Viejo Soil, most of them older than 4300 BP. In view of its low collagen content, the 14C measurement of bone sample from Luján should not be accepted uncritically. Because of the poor bone preservation and the possible introduction of “young” contaminants that were not completely eliminated, the 14C date of 4300 ± 90 BP is not reliable. Both biostratigraphic and 14C dating evidence indicates that the date of 4300 BP for the last representative of extinct megafauna in South America is unsupported.

“Al rico nunca le ofrezcan / y al pobre jamás le falten”. Estos versos del Martín Fierro -obra maestra de la narrativa gauchesca argentina- remiten al Monte de Piedad de Buenos Aires: por un lado, esencializan la función social como institución proveedora de crédito a los sectores desamparados de la sociedad, y por otro permiten identificar a su autor, José Hernández, como miembro del Consejo de Administración de la entidad y tenaz defensor de su continuidad.El presente artículo estudia, a partir de los antecedentes del crédito pignoraticio y del rol desempeñado por los montepíos nativos a mediados del siglo XIX, el origen y la trayectoria del Monte de Piedad de Buenos Aires, destinado a aliviar las penurias de los sectores vulnerados, tanto nativos como inmigrantes, evitando que sean víctimas de la usura. En tal sentido y desde una perspectiva macro que dé cuenta de la situación económico- financiera del país y particularmente de la provincia de Buenos Aires, se privilegia el análisis micro de las distintas etapas de la historia de este entidad y de su función social; desde su fundación en 1877 dependiente del Banco de la Provincia de Buenos Aires, su incorporación una década después al patrimonio municipal y su conversión en 1904 en Banco Municipal de Préstamos. El punto de partida es un estado de la cuestión sobre el tema. Las fuentes primarias (Libros de Actas, Memorias y balances, Cartas orgánicas, Reglamentos de la institución, Diario de Sesiones de la Legislatura bonaerense y del Consejo Deliberante de la ciudad de Buenos Aires) así como algunas publicaciones periódicas de la época, resultan sustantivas para lograr el objetivo propuesto. “Never offer to the rich /and may the poor never lack” These verses by Martín Fierro -a masterpiece of Argentine gaucho narrative- represent the Monte de Piedad in Buenos Aires and its development. In a way, they essentialize the social function of this institution that provides credit to the underprivileged sectors of society. Besides, this affirmation allows to identify its author, José Hernández, as a member of the entity’s Board of Directors and a tenacious defender of its continuity.This article is based on the antecedents of the pledge credit and the role played by the native montepíos in the mid-19th century. Its focused in the study of the origin and trajectory of Monte de Piedad in Buenos Aires, as an institution which alleviated the hardships of the vulnerable sectors, both natives and immigrants, and prevented them from being victims of usury. Both macro and micro perspectives converge in this analysis. Firstly, the argentine economic and financial situation is taken into account to get to Buenos Aires’ province evaluation. Secondly, the history of this entity’s social function is examined since it was founded in 1877 (under the Bank of the Province of Buenos Aires), to its incorporation a decade later into the municipal patrimony and its conversion into the Municipal Bank of Loans, in 1904.The article starts with a bibliographic review of this particular subject. The proposed objective is achieved by analyzing diverse primary sources (Minutes Books, Memories and balances, Organic Letters, Institution Regulations, Journal of Sessions of the Buenos Aires Legislature and the Deliberative Council of the city of Buenos Aires) as well as the main periodical publications of the time.

The glyptodont (Glyptodontidae Burmeister 1879, in Ameghino 1889), a giant cousin of the armadillo, has long been thought to have disappeared in South America at least 10,000 years ago at the end of the Pleistocene. There are indications that the glyptodont had some interaction with ancient hunter-gatherers peoples (Politis et al. 1987; Politis 1995), but the precise time of its extinction has never been well established. Most recently, a brief mention of 14C dates of 7500 to 6500 BP (Geotimes 1996) for glyptodont remains discovered at La Moderna (Azul Department, Buenos Aires province, Argentina), has aroused excitement because the new younger dates have changed the traditional idea about the survival and extinction of this beast.

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.

Mabuya dorsivttata is a lizard with a wide distribution in South America. In Buenos Aires province, Argentina, previous voucher records exist only from its northern sector and from Mar del Plata city. In this work, two new records of M. dorsivittata from Buenos Aires province are presented: (1) Azul city (36°46’50” S, 50°51’10” W) and (2) Mar del Tuyú city (37°20’08” S, 59°07’60” W). These new records are located about 175 km from the nearest previous record.

This paper reflects on the precautions to be taken into account when addressing the study, from the point of view of the social sciences, of cultures and communities. This is done through ethnographic research in a neighbourhood (barrio) of migrants from an indigenous community in the province of Chaco, in northern Argentina, who have migrated to the city of La Plata (in Buenos Aires province) and have settled on its periphery. The article starts from the idea that ethnicity comes into play, situationally, as a resource rather than as a distinct and immutable feature. Even when it is necessary to describe how notions like culture and ethnicity act in practice and what meaning they have for the actors, social researchers should not  historicize them in the specific contexts in which they are brought into play.Keywords: culture, ethnicity, indigenous community, ethnography, ArgentinaRésumé: Cet article met en évidence les précautions et les enjeux à prendre en considération en sciences sociales lorsque l’on aborde les questions culturelles dans les communautés. Cet article met en évidence un travail de terrain de type ethnographique dans un quartier (barrio) de La Plata (province de Buenor Aires) où se trouve une forte concentration de population migrante d’autochtones en provenance de la province de Chaco, dans le nord de l’Argentine. Plutôt que d’approcher l’ethnicité dans une perspective essentialiste et d’en faire une caractéristique immuable de l’identité, cet article s’inspire d’une approche relationnelle. Plutôt que de tenter de figer le sens de notions telles « ethnicité » ou «culture », cet article met en evidence l’importance de reconstruire le sens de ces notions à partir des données contextuelles et du sens qu’elles revêtent pour les acteurs.Mots clé: culture, ethnicité, communauté indigene, ethnographie, Argentine

Argentina, the second largest country in South America is a federation of 23 provinces and its capital, the autonomous city of Buenos Aires. Its population is a little over 40 million, 50% of whom reside in its five largest metropolitan areas. The rural areas are extensively under-populated. The city of Buenos Aires and its suburb contain 15.5 million inhabitants, making it one of the largest urban areas in the world.

A comparative study was made with the known record of equids species in South America, identifying the remains as Equus neogeus, Hippidion devillei, and Hippidion principale. These data increase the record of Equidae in South America and provide new evidence about the chronological and geographical distribution. The sedimentary deposits of the Lujan Formation outcropping at Tapalqué creek (4 to 120 ky) were accumulated through fluvial processes. This Formation comprises a rich vertebrate fauna corresponding to the Lujanian South American Land Mammal Age, which includes numerous and diverse vertebrate remains. The taphonomic analysis indicates that the faunistic assemblage was formed and was subject to diagenetic processes without distinction of its action in the fossiliferous levels, that can be recognized as fluvial deposits.

Former workers developed in South America a chronostratigraphic system not essentially different to that of European stage/age system. However, the authors of this paper believe that accurate biostratigraphic studies have to be done in southern South America for establishing the precise boundary stratotypes of most stage/ages. A new South American Upper Cenozoic continental stage/age is recognized. The stratotype is located in the fossiliferous southeastern Buenos Aires Province marine cliffs between Mar del Plata and Miramar. The outcrops in the area are the best continental representation of Plio-Pleistocene times in South America. It is younger than Chapadmalalan and older than Ensenadan and replaces the “Uquian”. We consider that the “Uquian” actually emcopasses Chapadmalalan and Ensenadan times. The Uquía outcrops are here considered inadequate as stratotype especially by the dearth of micromanmals, the relatively poor fossil record and the comparatively inadequate geographic location. The new stage would be correlated with the Gauss Chron and possibly with the lower Matuyama Chron. The lower boundary is tentatively stated. For so doing, a biostratigraphic scheme is proposed. This lower boundary approximately corresponds to the base of the Barranca de los Lobos “Formation” of Kraglievich (1952) and a new (unpublished) unconformity bounded unit (Zárate, 1989). Some taxa that apparently ranges from the base are candidates to define it after a detailed biostratigraphic study.Additionally, a different timing for the arrival of North American mammals to southern South America is given.

Abstract This recent case is a leading case relating to local trusts and forced heirship. Forced heirship is a restriction to the liberty to write a will and determine the destiny of his/her future estate by the testator. It can be found in all South America (not in Latin America from Panama to México) and in most Civil Law countries in Europe, besides similar restrictions under sharia law. The way to avoid these restrictions has been the creation of a foreign trust over foreign assets. Although authors have long analyzed whether a local trust allows the avoidance of local forced heirship rules over local assets, there has been no case law in this respect (at least since the inclusion of the trust in Argentine law in 1995). In short, this is the first time a local trust over local assets has been under the scrutiny of the courts to determine if there is a violation of forced heirship.
