Archaeological excavations conducted in Quinta do Almaraz (Almada, Portugal) between 1986 and 2001 have allowed to identify a settlement with an important Iron Age occupation. These interventions provided a large assemblage of faunal remains and its study has enabled a detailed analysis of the diet, lifestyle, and habits of the people who lived in Almaraz during the 1st millennium B.C. The most abundant mammal species are sheep and goat, followed by pig. Cattle and wild species, such as red deer, are also present. We likewise highlight a great variety of bird species, including the first remains of domestic galliformes, up to then an exotic animal in Europe. Regarding malacofauna, we highlight the prevalence of clam, cockle, mussel, winkle, and limpet.
