The Arrifes geosite: a fascinating glimpse into an Early Cretaceous ecosystem w...
Pereira, H. J. R.; Lopes, Francisco; Pérez-Cano, J.; Santos, Vanda Faria dos; Malafaia, Elisabete; Mendes, Márcia; Pereira, Zélia; Sweetman, Steven C.ABSTRACT: Over a century after Paul Choffat's initial description of the Arrifes section, a pioneering figure in Portuguese geology who highlighted the vertical arrangement of the strata and the occurrence of a limestone bed containing a copious quantity of orbitolinid tests, this upper Barremian–lower Aptian stratigraphic succession, which is fully exposed along a coastal cliff section located 2.5 km west-sout...
Study of the malacofauna found in the main hall of the Islamic palace of Silves...
Silva, Solange; Callapez, Pedro M.; Gomes, Rosa VarelaDuring an archaeological intervention carried out in the main palace hall of Silves Castle, in 2006, abundant malacological fauna was exhumed, contributing to the reconstitution of diets and cultural practices of the medieval populations that lived here. It was possible to count a minimum number of 5547 individuals, from 20 taxa of bivalve and gastropod molluscs, and cirriped crustaceans. This sample consists m...
Upper Barremian-lower Aptian charophyte biostratigraphy from Arrifes section (A...
Pérez-Cano, J.; Pereira, H. J. R.; Mendes, Márcia; Pereira, Zélia; Callapez, Pedro M.; Fernandes, PauloABSTRACT: The Arrifes section (Algarve Basin, Southern Portugal) has been studied from the viewpoint of char-ophyte biostratigraphy. The previous sedimentological studies in this section showed that it is built of the interbedding of continental and marine facies that contain both marine and continental palynomorphs (pollen, spores, and dinoflagellates), providing an excellent sedimentary context to perform dir...
Late Barremian–early Aptian charophytes from the Arrifes section (Algarve). Bio...
Pérez-Cano, J.; Pereira, H. J. R.; Mendes, Márcia; Pereira, Zélia; Callapez, Pedro M.; Fernandes, PauloSUMÁRIO: A secção estratigráfica dos Arrifes (Albufeira, Algarve) foi estudada, em detalhe, para biostratigrafia de carofitas. Este estudo permitiu-nos reconhecer duas associaçõoes distintas: i) A primeira, composta por Echinochara lazarii, Atopochara trivolvis triquetra, A. trivolvis trivolvis, Clavator grovesii jiuquanensis, Clavator harrisii harrisii e C. harrisii zavialensis, pertenece à biozona de Calvator...
Quistos de dinoflagelados do Cenomaniano médio da Nazaré. Paleoambientes e impl...
Fernandes, L. B.; Bonito, A.; Castro, Ligia; Alves, Maria Isabel C.; Callapez, Pedro M.RESUMO: No registo estratigráfico das séries pós-rifte do Cretácico Superior de Portugal destaca-se a Plataforma Carbonatada Ocidental Portuguesa, extenso corpo marinho do Albiano médio ao Turoniano inferior, contemporâneo de máximos eustáticos e inundação generalizada das margens continentais europeias e norte-africanas do Mar de Tétis. Considerado um dos seus principais afloramentos, o promontório da Nazaré e...

De trás para a frente: um retrato da Universidade de Coimbra na formação de pro...
Soares, Diana R.; Abrantes, Isabel; Callapez, Pedro M.; Lopes, BetinaA Educação em Ciências é fundamental para responder e minimizar desafios globais e locais do presente e do futuro. Por isso, é necessário assegurar uma formação de qualidade dos professores de Biologia/Geologia, em Portugal e no Mundo. Neste capítulo apresentam-se os resultados e as conclusões da análise documental feita a 39 relatórios de estágio pedagógico de (futuros) professores de Biologia/Geologia produzi...
Last Interglacial Iberian Neandertals as fisher-hunter-gatherers
Zilhão, João; Angelucci, Diego E.; Igreja, Marina; Arnold, L. J.; Badal García, Ernestina; Callapez, Pedro M.; Cardoso, João Luis; d’Errico, F.The origins of marine resource consumption by humans have been much debated. Zilhão et al. present evidence that, in Atlantic Iberia's coastal settings, Middle Paleolithic Neanderthals exploited marine resources at a scale on par with the modern human–associated Middle Stone Age of southern Africa (see the Perspective by Will). Excavations at the Figueira Brava site on Portugal's Atlantic coast reveal shell mid...
Last interglacial Iberian Neandertals as fisher-hunter-gatherers
Zilhão, J.; Angelucci, Diego E.; Igreja, Marina Araújo; Arnold, L. J.; Badal, E.; Callapez, Pedro M.; Cardoso, João Luís; d’Errico, F.; Daura, J.Marine food–reliant subsistence systems such as those in the African Middle Stone Age (MSA) were not thought to exist in Europe until the much later Mesolithic. Whether this apparent lag reflects taphonomic biases or behavioral distinctions between archaic and modern humans remains much debated. Figueira Brava cave, in the Arrábida range (Portugal), provides an exceptionally well preserved record of Neandertal ...
Composition of lower cretaceous mudstones of the Algarve basin and implications...
Dinis, Pedro A.; Carvalho, Joel; Callapez, Pedro M.; Mendes, Mario Miguel; Santos, Vanda F.; Manuel Carvalho Fernandes, PauloSeveral compositional features of mudstones are controlled by climate-driven weathering and have been used to approximate palaeoclimatic conditions. Mudstone composition, however, is also influenced by the geology of the source areas and diverse depositional and post-depositional processes. The present geochemical and mineralogical study of the Lower Cretaceous (upper Hauterivian to Aptian) of the Algarve Basin...
