The fossil record of birds from the James Ross Basin,West Antarctica

【摘要】 The fossil record of birds from Antarctica is concentrated in the James Ross Basin,located in north-east of the Antarctic Peninsula.Birds are here represented by an extensive Paleogene record of penguins(Sphenisciformes)and Cretaceous–Paleogene record of Anseriformes,followed by other groups with a minor representation(Procellariiformes,Falconiformes,and Pelagornithidae),and others previously assigned controversially to"Ratites",Threskiornithidae,Charadriiformes,Gruiformes,Phoenicopteriformes,and Gaviiformes.We provide a complete update of these records,commenting on the importance of some of these remains for the evolution of the major clades.更多还原
