A distal part of tibiotarsus from Charneca do Lumiar (Langhian, MN5) is identified as Palaeoperdix media, formerly known as
Miophasianus medius. This species is thus known on a large area of the Palearctic province, from Portugal to Poland, and from the beginning of the Middle Miocene (MN 5) to the beginning of the Upper Miocene (MN9). An indeterminate, Gruid from Quinta das
Pedreiras (Lower Langhian, MN4) and a few marine birds' remnants from Penedo Norte (Burdigalian) have been recognized
