Le Crétacé terminal de Beira Litoral, Portugal: remarques stratigraphiques et écologiques,étude complémentaire de Rosasia soutoi (Chelonii, Bothremydidae)

The synthetic study of the uppermost Cretaceous of the Beira Litoral (fauna, flora) confirms its upper Campanian-Maastrichtian age. It shows the presence of a tropical to subtropical climate in an area constituted by a low coastal plain only occasionally linked to the sea, saturated with fresh water and possessing accordingly, a predominantely freshwater fauna (Viso, Aveiro); this plain changed towards the interior into a drier more forested zone with a more abundant terrestrial fauna which includes mammals (Taveiro). A thorough study of the chelonian Rosasia, abundant on the coastal plain, was made possible thanks to the discovery of a skull: it demonstrates that the genus belongs to the family Bothremydidae, revalided here. The composition of this family is presented, its phylogenetic and paleobiogeographic relation with the other pleurodires are analyzed, and its diagnosis established. The family is constituted of three groups; Rosasia belongs to one of these, the Bothremys group.

Notas sobre depósitos de Taveiro estratigrafia, paleontologia, idade, paleoecologia

This paper reports some research work that has been done to support Geological Survey's field work for the 1:50.000 Carta Geológica de Portugal, (sheets 19-C Figueira da Foz and 19-D Coimbra-Lousã). Its main purpose was to establish the age of some continental formations. At Cerâmica do Mondego, Ld.ª near Taveiro, two series were observed. The lower one is mainly pelitic, montmorillonite being predominant. It also includes some sandy beds and channel deposits with high energy sediments (conglomerate with limestone pebbles). The upper series lies unconformably upon the former, and there is a neat discontinuity surface between the two. It mainly consists of sands, kaolinite being the most abundant of the clay minerals. This seems to indicate an intensive weathering, an acid, well drained environment and transportation by quite high energy running waters. No fossils were recorded. Preliminary paleontological results are presented, along with some data concerning other localities (Aveiro, etc.). Fossils found in the lower series are: gastropoda (Bulimus gaudryi, TV. 15 bed), several vertebrates (TV. 18), fishes (TV. 19?) and plants (TV. 19-TV. 24). Vertebrata belong to the same fauna as that from Vizo, Aveiro, etc. The presence of mammals is most important as only a single tooth was previously Know in Europe (Southern France) in Late Cretaceous formations. Elsewhere there are some mammalian remains in Peru besides the rich assemblages found in the USA and Mongolia. Plants are representative of the «Debeya flora» well known at several localities in Beira Litoral province, in «Buçaco sandstones», and in Lisbon's «Basaltic Complex». The most important stratigraphical conclusion is that the lower series is Upper Campanian and/or Maastrichtian in age, and not Tertiary as sometimes it has been considered. As at Aveiro, «Bebeya flora» occurs in-beds somewhat higher than those with the Aveiro-Vizo-Taveiro vertebrate fauna. Correlation with other «Debeya flora» localities are now more clear. Data concerning Taveiro lower series, in the whole, point out to a rather warm (and moist?) environment in an occasionally (seasonally?) flooded region.

Éssai de synthèse paléogéographique et paléobiostratigraphique du bassin occidental portugais au cours du crétacé supérieur

The Upper-Cretaceous transgressive serie is described by the authors, on the whole Occidental Portuguese Basin: it begins in the Lisbon region in the Albian and finishes in the Beira litoral province in the lower Turonian, while the sedimentation zones migrate Northward. The lithologic composition is given for each stage and sub-stage, taking into cgnsideration, in particular in the Upper Cenomanian, the lateral variations from one region to another. The paleogeography becomes clear by the study of the sedimentation environments (6 fig.). In conclusion, the authors propose a correlation between the whole serie and the accepted zonation of the Northwestern Europe. Tables show the repartition of the main macrofauna and microfauna.

Gestão Litoral: integração de estudos de percepção da paisagem e imagens digitais na definição da capacidade de carga de praias. O Troço Litoral S. Torpes - Ilha do Pessegueiro

O litoral, espaço geográfico de interface entre o meio marinho e terrestre, reúne múltiplos recursos que têm vindo a ser explorados ao longo dos tempos de uma forma cada vez mais intensa. A crescente ocupação humana das áreas litorais nos últimos 50 anos é disso um claro exemplo, chamando cada vez mais a atenção de entidades e especialistas de vários domínios científicos, para a necessidade de disciplinar e ordenar a exploração dos sistemas litorais. As praias, enquanto parte integrante destes sistemas, não fogem à situação descrita, uma vez que o turismo, entendido como uma das principais indústrias do final do século XX (Nordstrom, 2000), as elege como espaço privilegiado de destino, promovendo o desenvolvimento dos aglomerados adjacentes que suportam todas as actividades complementares ao turismo balnear. As áreas litorais em geral e as praias em particular, são excelentes exemplos de pontos de suporte da actividade turística, muitas vezes, a principal fonte de rendimentos para alguns países, como se pode depreender das palavras de Clark; “Good beaches are worth bilions of tourist dollars. Degraded beaches are worth little” (1995: 17). Assim, a praia pode ser considerada como um factor produtivo limitante do crescimento de um destino turístico, que tem de ser respeitado, para não existir uma degradação de condições que ponha em causa as suas características atractivas, geradoras de toda a riqueza. Mas a degradação das praias é, apenas, um entre vários impactos negativos provocados pela exploração massiva dos sistemas litorais e daí o seu estudo e preservação serem considerados cada vez mais cruciais em processos de desenvolvimento de efectiva sustentabilidade (Pesme, 1997).

Contributions to the Eocene palaeontology and stratigraphy of Beira Alta, Portugal II - New Late Eocene mammalian remnants from Coja (Portugal) and the presence of Palaeotherium magnum Cuvier

The presence of Palaeotherium magnum in the fauna from Coja is recorded. It is well in agreement with the earlier reporting to the Montmartre level from the Ludian stage. Field data as well as compatibility with the remaining taxa and the identical fossilization of all the specimens indicate that all the vertebrate fossils come from the same horizon in the lithostratigraphic unit "Arcoses de Côja".
