A marine bird (sulidae, Aves) from the Langhian (middle Miocene) of Penedo beach (Setúbal Peninsula—SW Portugal) and its paleoenvironmental context

Abstract

The fossil remains of birds from the Miocene of Portugal are scarce, encompassing a total of twelve specimens, from nine paleontological outcrops located in Leiria (central Portugal), southern sector of Setúbal Peninsula and along the lower Tagus Basin. This study focuses on a new specimen found in the Praia do Penedo Norte (Sesimbra) coastal cliff corresponding to a coracoid bone, attributed to Morus sp., a sulid bird, biostratigraphically framed by calcareous nannofossils within the middle Miocene (Langhian).
