Ensaio de síntese crítica acerca do Cretácico terminal e do Paleogénico de Portugal

A synthetic essay about portuguese Late Cretaceous (Upper Campanian-Maastrichtian) and Paleogene is presented. This does include most of the so far known data, a critical approach to the problems of such formations, and to previous works on them. Our viewpoints (party original) are exposed in a shorter text in French where most of the discussion was suppressed (see reference in Resumo).

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.

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.

Sélaciens du Miocène terminal du bassin d'Alvalade (Portugal). Essai de synthèse

A rich uppermost Miocene selachian fauna from the Alvalade Basin (represented by more than 10.000 teeth) is accounted for. It is the most modern miocene fauna of neritic habit under warm-temperate to subtropical conditions, known in the european Miocene.
