Richness of lichens growing on Eocene fossil penguin remains from Antarctica
Polar Biology, 2020 Antarctica presents one of the most severe environmental conditions for life. Under these circumstances, cryptogams are the dominant photosynthetic organisms, among which we find a great richness of lichens. In Antarctic environments, lichens can grow on rocks or in this case on fossil remains, among the few available substrates.

Early penguin fossils, plus mitochondrial genomes, calibrate avian evolution. [PDF]
Molecular Biology and Evolution, 2006 Testing models of macroevolution, and especially the sufficiency of microevolutionary processes, requires good collaboration between molecular biologists and paleontologists. We report such a test for events around the Late Cretaceous by describing the earliest penguin fossils, analyzing complete mitochondrial genomes from an albatross, a petrel, and a

A giant Oligocene fossil penguin from the North Island of New Zealand
Journal of Vertebrate Paleontology, 2021Penguins (Sphenisciformes) have arguably the most complete and continuous fossil record of any avian clade, offering an ever-improving understanding of penguin phylogeny, biogeography, and the evol...

Fossil Counterparts of Giant Penguins from the North Pacific
Science, 1979New fossils of giant, flightless penguinlike birds have been found in late Oligocene and early Miocene rocks in Japan and in the state of Washington. These birds belong to the order Pelecaniformes, in the extinct family Plotopteridae, previously known by a single fragment of bone from California.

Fossil Penguin from the Late Cenozoic of South Africa
Science, 1971Spheniscus predemersus , new species, from the late Pliocene of Langebaanweg, Cape Province, is the first fossil penguin to be described from Africa. It is closely related and possibly ancestral to the living species, Spheniscus demersus , of southern and southwestern Africa.

First penguin fossil (Aves, Spheniscidae) from Uruguay
Journal of South American Earth Sciences, 2019Abstract A fossil humerus coming from the Rocha Department coasts (Uruguay) is assigned here to Spheniscus cf. S. magellanicus (Aves, Sphenisciformes). This finding, located within the current migratory route of the species, potentially constitutes the northernmost fossil record of S.

The first record of fossil penguins from East Antarctica
Antarctic Science, 2012AbstractThis paper presents the first fossil penguin from East Antarctica, and the only one known south of the Antarctic Circle. It is represented by two well-preserved elements of the wing skeleton, humerus and radius, obviously assignable to the extant genus Spheniscus.

Journal of Vertebrate Paleontology, 2012
ABSTRACT Three skeletons collected from the late Oligocene Kokoamu Greensand of New Zealand are among the most complete Paleogene penguins known. These specimens, described here as Kairuku waitaki, gen. et sp. nov., and Kairuku grebneffi, sp. nov., reveal new details of key elements of the stem penguin skeleton associated with underwater flight ...
