Opis:
We describe a Cretaceous ?cimolodontan multituberculate p4 from South America, for which we erect the new genus and species Argentodites coloniensis. This new taxon is represented by an isolated ?left p4 from the Upper Cretaceous (?Campanian or Maastrichtian) La Colonia Formation of Patagonia (Fig. 1). It has a strongly convex anterior margin and prismatic enamel, which attest to its cimolodontan nature, while the previously known p4 (MACN−RN 975) from the Late Cretaceous Los Alamitos Formation is roughly rectangular, suggesting “plagiaulacidan” affinity. The presence of normal prismatic enamel in Argentodites suggests similarities to Ptilodontoidea. However, it differs from the Late Cretaceous and Paleocene Laurasian cimolodontans (including Ptilodontoidea) in having a long, straight posterior margin, a nearly straight dorsal margin, characteristic of some “Plagiaulacida”, and in having the lingual side close to the mirror image of the labial side, the character that poses difficulties in establishing whether it is a right or left tooth. Because of these differences we assign Argentodites to ?Cimolodonta, tentatively only, superfamily and family incertae sedis.

Opis:
The first localities of Juncus bulbosus (Juncaceae) for South America (Chile) and for the whole south-western part of the world (S latitude and E longitude) are described, including precise geographical location and climatic conditions. General remarks on the invasiveness of the species and on the possibility of finding it in other parts of the world are given. The distribution of the species world-wide requires further studies, since the bulbous rush has become an invasive plant in areas where it did not occur before.

The Australasian muricid gastropod Lepsiella as Pleistocene visitor to southernmost South America

Opis:
Six shells belonging to a muricid gastropod species were recovered from a Pleistocene marine raised beach located on Navarino Island, in southern South America. None of the living species in the Beagle Channel or in the area is close, and none of the fossil species in the vicinity regions shows the diagnostic characters of the Navarino Pleistocene fossils. Our material resembles Lepsiella baileyana from southern Australia, although some differences in the suture and in the spire outline are recognized. Haustrinae were previously confined geographically to New Zealand and to the temperate coast of Australia, now extending its range of distribution to southern South America. This finding of Lepsiella ukika sp. nov. is best explained on the basis of transoceanic migration from Australasia by means of the Antarctic Circumpolar Current perhaps during a Quaternary glacial period. The presence of this Pleistocene visitor in southern South America is important because it clearly demonstrates that transcontinental traverse of taxa with direct (non−planktonic) development might have happened by rafting on kelp that served as transport platforms.

Opis:
The Uruguay River basin in South America has held a social, cultural, environmental, and economic relevance for many centuries. The river flows for about 2,000 km, linked to an important remnant of native forest, the Selva Misionera in Argentina, and to a Brazilian conservation unit for biodiversity, the Turvo State Park. The Uruguay River is fed by several other important rivers, forming a basin region in which thousands of people live and work. The history of the Uruguay River is intensively linked to the permeable borders between Brazil, Argentina, and Uruguay where different social groups circulated in diverse historical time periods. Forests along the river played a very important role with emphasis on the extraction and trade of yerba mate (Ilex paraguariensis, Saint-Hilaire), a forest product widely consumed in southern America, and also the timber extraction from native forests, during the nineteenth and twentieth centuries. As a result, a profound socio-environmental transformation took place with the reconstruction of regional landscapes shaped by the Uruguay River basin.

Opis:
The subfamily Glyptodontinae (Xenarthra, Cingulata) comprises one of the most frequently recorded glyptodontids in South America. Recently, the North American genus Glyptotherium was recorded in South America, in addition to the genus Glyptodon. It has been shown that both genera shared the same geographic distribution in central-north and eastern areas of South America (Venezuela and Brazil, respectively). Although some characters allow differentiation between adult specimens of both genera, the morphological distinction between these two genera is rather difficult in juvenile specimens. In this contribution, a detailed morphological, morphometric and histological survey of a juvenile specimen of Glyptodontinae recovered from the Late Pleistocene of northern Brazil is performed. The relative lower osteoderms thickness, the particular morphology of the annular and radial sulci and the distal osseous projections of the caudal osteoderms suggest that the specimen belongs to the genus Glyptotherium. In addition, the validity of some statistical tools to distinguish between different ontogenetic stages and in some cases between genera is verified. The osteoderm microstructure of this juvenile individual is characterized by being composed of a cancellous internal core surrounded by a compact bone cortex. Primary bone tissue mostly consists of highly vascularized, woven-fibered bone tissue. Unlike that observed in adult Glyptodontinae, both the Sharpey fibers and the fibrous and laminar parallel bone tissue as secondary bone are absent. This study enhances our knowledge about those morphological and histological changes that occur through the ontogeny in glyptodonts.

Opis:
We describe a new large species of marabou stork, Leptoptilus patagonicus(Ciconiiformes, Ciconiidae, Leptoptilini), from the late Miocene Puerto Madryn Formation, Chubut Province, Argentina. The specimen consists mainly of wing and leg bones, pelvis, sternum, cervical vertebrae, and a few fragments of the skull. We provisionally adopt the traditional systematic scheme of ciconiid tribes. The specimen is referred to the Leptoptilini on the basis of similarities in morphology and intramembral proportions with the extant genera Ephippiorhynchus, Jabiru, and Leptoptilos. The fossil specimen resembles in overall morphology and size the species of Leptoptilos, but also exhibits several exclusive characters of the sternum, humerus, carpometacarpus, tibiotarsus, and pelvis. Additionally, its wing proportions differ from those of any living taxon, providing support to erect a new species. This is the first record of the tribe Leptoptilini in the Tertiary of South America.

Opis:
Official dollarization is a strategy for monetary and exchange rate policy, which means resignation from national currencies. It is a solution which can be used for different purposes, both offensive and defensive, as evidenced by the examples of Ecuador, El Salvador and Panama. The description of the meaning and effects of dollarization may be important both in the context of developing countries as well as in terms of the issue of global monetary order, an element of which is among others monetary integration in the form of the euro area. The official dollarization literature includes Berg and Borensztein’s work [2000] about the pros and cons of official dollarization, Chang and Velasco’s [2002] on the consequences of dollarization for prosperity, Barro’s [1999] which is the official dollarization recommendation for South America countries, Edwards’ [2002] and Edwards and Magendzo’s [2003] containing empirical testing of the effects of official dollarization for the economic growth. The description and assessment of the effects of monetary policy is an important issue which fits into a much larger current issues of global monetary order determining the significance of currencies of particular countries and currency areas and thus their economies in the international division of labor. Official dollarization and the entry to the euro zone despite their differences contain common elements, such as the abandonment of the exchange rate policy and the reduction of the importance of monetary policy, which confirms the usefulness of this study.
