Taxonomic revision of Eocene Antarctic penguins based on tarsometatarsal morphology
A Myrcha,Piotr Jadwiszczak,C.P. Tambussi,J.I. Noriega,A. Gazdzicki,Andrzej Tatur,R.A. Del Valle +6 more
TL;DR: Gradual cooling of climate, changes of environment and trophic relationships, that lasted several millions years, were most probably responsible for the intense speciation and taxonomic diversification of the Middle-Late Eocene La Meseta penguins.
Journal Article
Eocene penguins of Seymour Island, Antarctica: Taxonomy
Andrzej Myrcha,Piotr Jadwiszczak +1 more
TL;DR: It is suggested that ten species grouped in six genera are a minimal reliable estimate of the Eocene Antarctic penguin diver− sity, which may have co−existed in the Antarctic Peninsula region during the Late Eocene epoch.
Journal Article
Penguin past: The current state of knowledge
TL;DR: What the authors currently know about extinct penguins is summarized and indirectly suggests the most promising areas for further research.

Aspects of diversity in early Antarctic penguins
Piotr Jadwiszczak,Thomas Mörs +1 more
TL;DR: It is suggested that Antarctic species of Anthropornis and Palaeeudyptes, so-called giant penguins, may in fact comprise only one species each instead of two, based on evidence of well-marked sexual dimorphism.
Journal Article
Eocene penguins of Seymour Island, Antarctica: The earliest record, taxonomic problems and some evolutionary considerations
TL;DR: Penguin bones from the La Meseta Formation (Seymour Island, Antarctic Penin− sula) are the only record of Eocene Antarctic Sphenisciformes as mentioned in this paper.
