High-precision U-Pb zircon age from the Anfiteatro de Ticó Formation: Implications for the timing of the early angiospermdiversification in Patagonia
(Elsevier, 2013-08)
The Baqueró Group is one of the most relevant units regarding the study of the early diversification of angiosperms in South America. Whereas the age of the upper part of the Group, namely the Punta del Barco Formation, ...
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 ...
New Species of Conifer Wood from the Baqueró Group (Early Cretaceous) of Patagonia
(Asociación Paleontológica Argentina, 2015-08)
The Baqueró Group is a continental sequence deposited during the late Aptian in Patagonia (Césari et al., 2011; Limarino et al., 2012; Perez Loinaze et al., 2013). During more than fifty years the Baqueró deposits have ...

- 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 ...
Resolving Australian analogs for an Eocene Patagonian paleorainforest using leaf size and floristics
(Botanical Society of America, 2015-07)
• Premise of the study: The diverse early Eocene flora from Laguna del Hunco (LH) in Patagonia, Argentina has many nearest living relatives (NLRs) in Australasia but few in South America, indicating the differential survival ...

The Huitrera Formation is a sequence of volcanic deposits that outcrops in the northwestern region of Patagonia. Several paleofloras have been recognized in this (or in coeval) units, in classical localities named Pichileufu, ...
Fossil woods from the Eocene of Corcovado, Argentinean Patagonia: geological setting and conifer diversity
(International Association of Wood Anatomists, 2021-05)
Eocene paleofloras of Patagonia are diverse and increasingly known. A new assemblage of fossil wood has been recovered from Eocene sediments in Corcovado, western Argentinean Patagonia. The lithological succession (formerly ...
A new paleofloristic assemblage from the Cuyana Basin (Agua de los Pajaritos depocenter), Argentina and its paleobiogeographic and paleoenvironmental implications
(Pergamon-Elsevier Science Ltd, 2020-12)
In this study, we examined the first paleofloristic record for the Monina Formation, Middle Triassic, Agua de los Pajaritos depocenter, Cuyana Basin, San Juan Province, Argentina. The paleoflora includes representatives ...
