Résumé
The Cabrela Basin (western Ossa-Morena Zone) has been the subject of a detailed geologic study in the past few years. This work is part of that study, focusing on the conodont and dacryoconarid biostratigraphy of the carbonate rocks of the basin, namely, the sequence of the Pedreira da Engenharia Formation, which is exposed in an ancient quarry. This sequence has allowed the recognition of two conodont zones (costatus and australis), corresponding to an early to middle Eifelian age. Due to the poor preservation of the dacryoconarids, no identification was possible until now.
