Dinossáurios Eocretácicos de Lagosteiros

According to an ancient folkloric legend, Our Lady, stepping down from the sea, would have rided on a mule to the platform above the cliffs named Pedra da Mua at Lagosteiros'bay, near Espichel cape. Mule's footprints, regarded by fishermen as evidence, would be clearly recognizable on exposed surfaces of the rocks. Indeed there are footprints but from Dinosaurs of latest Jurassic, Portlandian age, this spectacular locality being specially rich in giant Sauropod tracks (that have seldom been found elsewhere in Europe). As we proceeded to its study, another locality with Dinosaur footprints, Lower Cretaceous (Hauterivian) in age, was found on the northern cliffs at Lagosteiros. It is probably the richest one in european Lower Cretaceous and the only of this age known in Portugal, so we decided to give priority to its study. Dinosaur tracks have been printed on calciclastic sands in a lagoonal environment protected by fringing coral reefs. There have been emersion episodes; beaches were frequented by Dinosaurs. Later on, the marine barremian ingression restablished a gulf and such animals could not come here any more. Under a paleogeographical viewpoint, the evidence of a marine regression near the end of Hauterivian is to be remarked. Five types of tracks and footprints have been recognized: - Neosauropus lagosteirensis, new morphogenus and species, tracks from a giant Sauropod, perhaps from Camarasaurus; with its proportions the total length of the author would be about 15,5 m. These are the only Sauropod tracks known till now in Europe's Lower Cretaceous. - tracks from a not so big quadruped, maybe a Sauropod (young individual?); however it is not impossible that they were produced by Stegosaurians or Ankylosaurians. -Megalosauropus (?Eutynichnium) gomesi new morphospecies, four Theropod tracks most probably produced by megalosaurs. - Iguanodon sp., represented by some footprints and specially by a set corresponding to the feet and tail from an individual standing in a rest position. - problematical, quite small-sized biped (maybe an Ornithopod related to Camptosaurus). Evidence points to a richer fauna than that known in barremian "Dinosaur sandstones" from a nearby locality, Boca do Chapim. Lagosteiros' association clearly indicates the predominance of herbivores, which required large amounts of vegetable food in the neighbourhood. This is an indirect evidence of the vegetal wealth, also suggested by associations of plant macrofossils, polen and spores found in early Cretaceous sediments at the same region. The relatively high proportion of Theropoda is related to the wealth of the whole fauna, which comprised a lot of the prey needed by such powerful flesh-eaters. The evidence, as a whole, points out to a warm and moist climate. All the tracks whose direction could be measured are directed to the southern quadrants, this being confirmed by the approximative direction of other footprints. Massive displacements (migration?) could take place during a brief emersion episode. This may result from the ingression of barremian seas, flooding the region and restablishing here a small gulf. Even if the arrival of the waters damaged certain footprints it has not destroyed them completely, thus allowing the preservation of such evidence from a remote past.

Les faunes de coraux (Anthozoaires Scléractiniaires) de la façade atlantique française au Chattien et au Miocène

The study of new abundant coral crops and a systematic revision of the historic collections allow us to extend significantly the data about the Upper Oligocene and Miocene Scleractinia of the French atlantic basins. The SW and W-NW France faunas have been considered, and complete lists of the different defined taxa are presented. The generallines of the evolution of this group are specified, and linked to the paleoclimatic and paleobiogeographic changes.

Analyse paléoécologique des formations récifales du golfe de Skoura (bordure méridionale du sillon Sud rifain; SE de Fés; Maroc). Implications paléogéographiques: communications Atlantique - Méditerranée au Miocène Terminal

The reef levels of the gulf of Skoura belong to the reef formation of the Upper Miocene of the South-Rifan straits. A detailed analysis of the vertical distribution of various forms of colonies has led to the establishment of precise coral morphologies zonation. This palaeoecological approach leads us to distinguish between two environments in the Skoura gulf, probably corresponding to two reef episodes. The palaeogeographical implications (relationships between the Atlantic ocean and the Mediterranean sea) will be pointed out.

A disciplina de canto coral no Estado Novo: contributo para a História da Educação Musical em Portugal

Dissertação de Mestrado em Ciências Musicais (Especialidade de Ciências Musicais Históricas)

A prática interpretativa da música coral portuguesa do século XVII: análise de registos fonográficos da música da Escola da Sé de Évora (1980‐2013)

Os estudos na área da Performance Practice têm conhecido, nos últimos dez anos, uma grande expansão no meio académico. Os trabalhos, neste campo, repartem-se por três grandes temas que reflectem a diversidade de metodologias e perspectivas deste campo de estudos: teoria da interpretação, prática interpretativa e interpretação historicamente informada. O tema desta dissertação recai sobre este último tópico. O projecto incide sobre a interpretação histórica e os pressupostos teóricos que fundamentam as práticas interpretativas da musica coral seiscentista ibérica. Através da recolha e análise de um corpus de registos fonográficos da polifonia dos compositores que se formaram na Escola de Música da Sé de Évora, pretende-se compreender qual o peso da evidência documental nas opções interpretativas. Além da análise das gravações, foi realizado um questionário aos directores corais sobre os critérios na escolha de diversos parâmetros como transposição, tactus, articulação, dimensão do coro, entre outros.
