  • A new species of the genus Megapaleolodus (Aves: Phoenicopteridae: Palaelodinae) fromthe Upper Miocene of Northwestern Argentina. A new species of the genus Megapaloelodus is describedin this paper. The new species, named M. peiranoi nov. sp. was found in outcrops of the Upper Miocene AndalhualáFormation, in Catamarca province, NW Argentina. The new species differs to other previously describedMegapaloelodus species and shows several elements that were poorly described by previous authors. Cervicalvertebrae may be distinguished from those present in the remaining phoenicopterids in having wider and shortercentra. Medium dorsals are free. The notarium is shortened and is formed by two laterally compressed vertebrae.These vertebral traits are highly reminiscent of the basal phoenicopterid Juncitarsus and the Charadriiformes,and are probably indicative of the basal position of the genus within Phoenicopteridae.
