Stratigraphy
| Stratigraphy comments: Zone VIIb (Berkeley Cotter, 1904); horizon of Pecten scabrellus var. macrotis
Cotter‟s lithostratigraphic zone VIIb [95] includes the youngest Miocene rocks present in the Lower Tagus Basin. At Adiça, the exposed rock seems to date to the middle or late Tortonian (9.5–8.5 Ma) [96, 97]. Together, this indicates a total age range of 11.7–8.5 Ma. (Marx & Fordyce, 2015). The skull was retrieved from the Miocene, lower Tortonian [49], Lisbon Miocene Cotter’s division VIIb (ca. 10 Ma) [50]. According to Vandelli [24], the skull was found in thick dark green limestone, full of invertebrate shells. |
