Geoconservation in the Cabeço da Ladeira Paleontological Site (Serras de Aire e...

The Cabeço da Ladeira paleontological site in central Portugal became known as the “Jurassic Beach”. Formerly an active quarry, the site was protected in order to preserve the large exposures of a Middle Jurassic (early? Bajocian) carbonate tidal flat with an outstanding fossil record. This multidisciplinary paleontological work involving experts from several national and international research and geoconservat...

Running crabs, walking crinoids, grazing gastropods: behavioral diversity and e...

Ichnology is a powerful tool for understanding the evolutionary paths of animal clades, through the paleobiology of behavior preserved in Lagerstätten such as the Cabeço da Ladeira (Portugal) site. Here, the peritidal carbonates of the Chão das Pias Formation (Middle Jurassic, upper Bajocian) record the development of microbial mats in a tidal flat. Episodically, the flat was expanded during periods of equinoct...

Equinodermes do Cabeço da Ladeira : um caso de preservação do património geológico

O presente trabalho pretende descrever o processo de intervenção no geossítio Equinodermes do Cabeço da Ladeira, concelho de Porto de Mós. Este local foi assim classificado por conter fósseis de equinodermes detentores de importância científica significativa, merecendo especial atenção e medidas de preservação. Expõem-se os passos tomados desde a sua identificação ate às ações mais recentes, que envolveram a in...

Typological classification of clayey raw materials for ceramics manufacture, in...

Mapping of clay resources in the Cenozoic deposits of the Ta´bua region (central Portugal) has been carried out, together with the chemical, mineralogical and technological characterization of seventeen clay samples. The study was undertaken to relate the lithostratigraphic units and the typology of raw materials with regard to the manufacture of ceramics. The sedimentary succession comprises two units with dif...
