The last dinosaurs of Brazil: The Bauru Group and its implications for the end-Cretaceous mass extinction

ABSTRACT The non-avian dinosaurs died out at the end of the Cretaceous, ~66 million years ago, after an asteroid impact. The prevailing hypothesis is that the effects of the impact suddenly killed the dinosaurs, but the poor fossil record of latest Cretaceous (Campanian-Maastrichtian) dinosaurs from outside Laurasia (and even more particularly, North America) makes it difficult to test specific extinction scenarios. Over the past few decades, a wealth of new discoveries from the Bauru Group of Brazil has revealed a unique window into the evolution of terminal Cretaceous dinosaurs from the southern continents. We review this record and demonstrate that there was a diversity of dinosaurs, of varying body sizes, diets, and ecological roles, that survived to the very end of the Cretaceous (Maastrichtian: 72-66 million years ago) in Brazil, including a core fauna of titanosaurian sauropods and abelisaurid and carcharodontosaurid theropods, along with a variety of small-to-mid-sized theropods. We argue that this pattern best fits the hypothesis that southern dinosaurs, like their northern counterparts, were still diversifying and occupying prominent roles in their ecosystems before the asteroid suddenly caused their extinction. However, this hypothesis remains to be tested with more refined paleontological and geochronological data, and we give suggestions for future work

Os caminhos da fonoaudiologia no Sistema Único de Saúde - SUS The ways of the speech-language therapy in the Unique System of Health - SUS

TEMA: os caminhos da Fonoaudiologia no Sistema Único da Saúde - SUS. OBJETIVO: realizar um breve relato da evolução das questões de saúde no Brasil e da evolução do serviço de Fonoaudiologia no Sistema Público além de realizar uma breve análise sobre a importância de pesquisas nesta área. CONCLUSÃO: o serviço de Fonoaudiologia vem apresentando avanços significativos no Sistema Único de Saúde. Desde sua inserção no SUS, entre as décadas de 70 e 80, muitos conceitos e práticas têm sido reavaliados. No entanto, é preciso que se tenha conhecimento desta caminhada para que seja possível fazê-la avançar cada vez mais. Acredita-se que este serviço merece importante atenção das ações de saúde pública e que são necessárias evidências científicas que comprovem a importância deste trabalho.<br>BACKGROUND: the ways of the speech-language therapy in the Unique System of Health - SUS. PURPOSE: to accomplish a brief report about the health questions evolution in Brazil and speech-language therapy service evolution in the Public System, in addition to carry through a quick analysis on the concern of research in this area. CONCLUSION: speech-language therapy service has been presenting significant advances in the Unique System of Health. Since its insertion in SUS, between the decades of 70 and 80, many conceptions and practices have been reevaluated. However, it is necessary to have acquaintance on this step so that we can make it to advance each time more. We believe that this service deserves important attention from the actions of public health and that scientific evidences are necessary in order to prove the significance of this work
