| Resumo: | A quantitative taphonomic analysis were performed in the fossil assemblages of the late Tortonian of the lower-mid part of the Cacela Formation (Cacela, Algarve, S Portugal). Taphonomic results, together with sedimentological analysis and the faunal assemblages, allow to inferring palaeoenvironmental changes. The upper Tortonian sedimentation started with fan-delta conglomerates that quickly changed to outerplatform silty marls deposited in a setting with a relatively low sedimentation rate as indicated by the concentration of glauconite. Higher up into the section, a progressive shallowing trend is inferred, and sediments of inner platform settings were formed |
