The Late Pleistocene avifauna from Artazu VII (Basque Country, northern Iberian Peninsula)

Abstract

ABSTRACTThis study is a contribution to the knowledge of ancient avifauna in the Iberian Peninsula. 1,786 bird bones have been recovered from Artazu VII (Arrasate, northern Iberian Peninsula), with 239 remains identified to Order/Family and 519 to Genus/Species level, belonging to, at least, 12 taxa: Buteo lagopus, Aquila chrysaetos, Perdix perdix, Coturnix coturnix, Alectoris sp., Lyrurus tetrix, Crex crex, Bubo cf. bubo, Corvus monedula, Pica pica, Pyrrhocorax pyrrhocorax and Pyrrhocorax graculus. The best represented taxa are corvids, followed by L. tetrix. The most significant finding is the presence of B. lagopus, which represents the second fossil record in the Iberian Peninsula. The morphometric analyses performed for C. coturnix and L. tetrix contribute to the knowledge of those taxa measurements, due to the Artazu VII assemblage being one of the best samples of these taxa in the Iberian Peninsula for the late Pleistocene. All the measurements of B. lagopus and C. coturnix have been analysed statistically. A brief taphonomic study has been carried out to identify the bird accumulation agent. Finally, a palaeoenvironmental analysis is based on the bird assemblage and ecology, and this new information is compared to palaeoenvironmental data inferred from vertebrates at Artazu VII in previous studies.
