None of the four numerical dates presented were obtained from the Oura section. Instead, they derive from different outcrops and different sections, with no direct correlations. In addition, no reference to isotopic dates from the Oura section published in Pais et al. (2000) was made despite the paper was cited by Cachão et al. (2009). Also, some paleontological and biostratigraphic data (Antunes et al. 1981) concerning the Oura section are not discussed.The Oura Neogene section coordinates (Google) are 37°05′02″/8°13′50″. In fact, the numerical dates of 8.15 Ma (±0.29) and 7.15 Ma (±0.27) presented in the lower part of bed 3 (Fig. 2; Cachão et al. 2009) were obtained by Boski et al. (1995) in glauconi

Both the palynoflora and mesofossil flora are poor in species diversity and in number of specimens. The palynological assemblage is dominated by pteridophytes and gymnosperms. The mesofossil flora is dominated by conifer
