Enigmatic morphological disparity in tarsometatarsi of giant penguins from the Eocene of Antarctica

The only record of the Paleogene Antarctic Sphenisciformes comes from the Eocene La Meseta Formation (Seymour Island, Antarctic Peninsula). The analysis of tarso− metatarsi attributed to the genus Anthropornis (“giant” penguins) from the Argentine, Pol− ish and Swedish collections revealed an intrig...
