First record of Todea (Osmundaceae) in South America, from the early Eocene paleorainforests of Laguna del Hunco (Patagonia, Argentina)
(Botanical Society of America, 2013-09)
Premise of the Study: The early Eocene Laguna del Hunco caldera-lake paleoflora (ca. 52 Ma) from Chubut Province, Argentina, is notably diverse and includes many conifer and angiosperm lineages that are extinct in South ...
Palaeoenvironmental and palaeoecological implications from body fossils and ovipositions of Odonata from the Eocene of Patagonia, Argentina
(Brill Academic Publishers, 2013-06)
Odonata are beginning to be well recorded in the Eocene of Patagonia, Argentina. They are represented by body fossils and traces in three localities. Oviposition scars are recorded in Río Pichileufú (Lutetian: 47.7 Ma; Río ...
A new burmagomphid dragonfly from the Eocene of Patagonia, Argentina
(Polish Academy of Sciences. Institute of Paleobiology, 2017-11)
A new burmagomphid anisopteran, Satelitala soberana gen. et sp. nov. is described from the lower Eocene of Laguna del Hunco, Patagonia, Argentina. The new genus is characterised by hindwing characters such as the subdiscoidal ...
Eocene Fagaceae from Patagonia and Gondwanan legacy in Asian rainforests
(American Association for the Advancement of Science, 2019-06)
The beech-oak family Fagaceae dominates forests from the northern temperate zone to tropical Asia and Malesia, where it reaches its southern limit. We report early Eocene infructescences of Castanopsis, a diverse and ...
A new Frenguelliidae (Insecta: Odonata) from the early Eocene of Laguna del Hunco, Patagonia, Argentina
(Magnolia Press, 2013-02)
The discovery of a new specimen of Frenguelliidae, attributed to the new species Frenguellia iglesiasi, in Patagonia, Argentina, is noteworthy for the knowledge of the diversity within this little-known family.
A silicified Todea trunk (Osmundaceae) from the Eocene of Patagonia
(Springer Heidelberg, 2019-08-01)
The Osmundaceae family is the sister group to all other extant leptosporangiate ferns. Its rich fossil record has enabled detailed reconstructions of the evolutionary history of the group. Fossil evidence for today’s ...
Conifer wood assemblage dominated by Podocarpaceae, early Eocene of Laguna del Hunco, central Argentinean Patagonia
(Pensoft Publishers, 2020-08)
During the early Eocene, Patagonia had highly diverse floras that are primarily known from compression and pollen fossils. Fossil wood studies from this epoch are scarce in the region and largely absent from the Laguna del ...
Early eocene spore and pollen assemblages from the laguna del hunco fossil lake beds, patagonia, argentina
(University of Chicago Press, 2020-07)
Premise of research. The early Eocene Laguna del Hunco (LH) fossil site, northwestern Chubut Province, Argentina, holds one of the best-preserved and most diverse paleofloras worldwide. The paleoflora comprises ferns, ...

- Premise of the study: Agathis is an iconic genus of large, ecologically important, and economically valuable conifers that range over lowland to upper montane rainforests from New Zealand to Sumatra. Exploitation of its ...
The last patagonian cycad, austrozamia stockeyi gen. et sp. nov., early eocene of laguna del hunco, Chubut, Argentina
(National Research Council Canada-NRC Research Press, 2016-09)
The cycads pose classic problems in evolutionary biogeography, owing to their far-flung extant distributions and the sparse fossil records of living genera. A noteworthy example is Tribe Encephalarteae of Family Zamiaceae, ...
