The analysis of tarso− metatarsi attributed to the genus Anthropornis (“giant” penguins) from the Argentine, Polish and Swedish collections revealed an intriguing heterogeneity within these taxonomically important elements of the skeleton. The unique hypotarsal morphology challenges the current systematics of large−bodied penguins and sheds new light on their evolution.}, type={Artykuły / Articles}, title={Enigmatic morphological disparity in tarsometatarsi of giant penguins from the Eocene of Antarctica}, URL={http://www.journals.pan.pl/Content/99496/PDF/10183_Volume32_Issue2_07_article.pdf}, doi={10.2478/v10183−011−0013−9}, keywords={Antarctic Peninsula, Eocene La Meseta Formation, penguins, Anthropornis, tarsometatarsi}, }
