- Lower Devonian faunas and palynomorphs from the Dornes Syncline, Central Iberiam Zone, Portugal : stratigraphical and paleogeographical implicationsPublication . Gourvennec, Rémy; Piçarra, José Manuel; Plusquellec, Yves; Pereira, Zélia; Oliveira, José Tomás; Robardet, MichelIn the Dornes syncline, southern Central Iberian Zone, Portugal, the uppermost levels of the Serra do Luação Formation up to now have been considered to be of Pridoli-Lochkovian? age because they lie immediately under the Dornes Formation, which is of Pragian age and is well defined stratigraphically. New paleontological elements including benthic faunas and palynomorphs allow us to confirm that the top of the Serra do Luação Formation is securely Lochkovian, for upper Lochkovian strata are present although relatively thin. The transition from the Serra do Luação to the Dornes formations and their lithostratigraphical relationship are now clear: the terrigenous succession belongs in the Serra do Luação Formation and the limestones represent the Dornes Formation. The benthic faunas clearly have North-Gondwanan affinities.
- A reassessment of the Lochkovian, Lower Devonian, benthic faunas and palynomorphs from the Dornes region, southern Central Iberian Zone, PortugalPublication . Gourvennec, Rémy; Plusquellec, Yves; Pereira, Zélia; Piçarra, José Manuel; Le Menn, J.; Oliveira, José Tomás; Romão, José; Robardet, MichelA revision of benthic faunas and palynomorphs previously described from the Dornes syncline, southern Central Iberian Zone, Portugal, complemented with recent research, shows that the Serra de Luação Formation is of Lochkovian age. The systematics of the benthic faunas, with clear Gondwana affinities, are described in detail.
