Fossil clitellate annelid cocoons and their microbiological inclusions from the Eocene of Seymour Island, Antarctica
(Coquina Press, 2016-03)
Clitellate annelids have a meagre body fossil record but they secrete proteinaceous cocoons for the protection of eggs that, after hardening, are readily fossilized and offer a largely untapped resource for assessing the ...
Phylogeny of the Eocene Antarctic Tapetinae Gray, 1851 (Bivalvia, Veneridae) from the la Meseta and Submeseta formations
(Paleontological Society, 2020-06)
Systematic analysis shows that the Southern Hemisphere bivalve genus Retrotapes includes the Antarctic species R. antarcticus, R. newtoni, and R. robustus and recognizes for the first time the presence of Katelysia represented ...
First bird remains from the Eocene of Algarrobo, central Chile Primeros restos de aves del Eoceno de Algarrobo, Chile central
(2012)
Paleogene records of birds in the Eastern margin of the Pacific Ocean have increased in recent years, being almost exclusively restricted to fossil Sphenisciformes (penguins). New avian remains (Ornithurae, Neornithes) ...
Middle Eocene deformation and sedimentation in the Puna–Eastern Cordillera transition (23°–26°S): Control by preexisting heterogeneities on the pattern of initial Andean shortening
(Geological Society of America, 2007-12)
The Quebrada de los Colorados Formation, at the north end of Calchaquí Valley in Salta Province, northwest Argentina, preserves evidence of syndepositional deformation since the middle Eocene (ca. 40 Ma) that includes (1) ...
A new penguin cranium from Antarctica and its implications for body size diversity during the Eocene
(E Schweizerbartsche Verlags, 2017-11)
Although penguins have a very abundant fossil record in Antarctica, very few cranial elements have been found so far, and in all the cases the specimens are incomplete. We describe a new cranium of a medium-sized penguin ...
Conifer fossil woods from the La Meseta Formation (Eocene of Western Antarctica): Evidence of Podocarpaceae-dominated forests
(Elsevier Science, 2013-09-20)
A new collection of 120 fossil wood samples from early Eocene sediments of the La Meseta Formation is studied. Conifers represent 68 % of the total amount of wood samples. The specimens show significant conifer diversity ...
