Brackish to freshwater dinoflagellate cyst assemblages from the La Colonia Formation (Paleocene?), Northeastern Patagonia, Argentina.Asociaciones de quistes de dinoflagelados de agua salobre a dulce de la formacion la colonia (Paleoceno?), noreste de Patagonia, Argentina
(Asociacion Paleontologica Argentina, 2014-04)
The palynological analysis of the La Colonia Formation at the San Miguel section yielded conspicuous organic-walled dinoflagellate cyst (dinocyst) and green algae assemblages. The presence of a monotypic palaeoperidinioid ...
Malvinia escutiana, a new biostratigraphically important Oligocene dinoflagellate cyst from the Southern Ocean
(Elsevier Science, 2011-06)
The Eocene-Oligocene Transition (EOT, ~. 34. Ma) represents the culmination of Eocene cooling by the initiation of large-scale Antarctic glaciation. Recognition and correlation of the EOT in Southern Ocean sedimentary ...
A Danian subtropical lacustrine palynobiota from South America (Bororó Formation, San Jorge Basin, Patagonia - Argentina)
(Universidad de Barcelona, 2009-06)
New results on a lacustrine Danian palynological association in extra-andean northern Patagonia (lower member of the Cerro Bororó Formation, San Jorge Basin, Chubut province, Argentina) are presented. This is a contribution ...
Environmental variables database from a Miocene marine stratigraphic section: a multivariate statistical analysis
(Elsevier, 2021-06)
The data presented here are related to the research article “Miocene Atlantic transgressive-regressive events in northeastern and offshore Patagonia: A palynological perspective” (Guler et al. 2021; https://doi.org/10.10 ...
Bioestratigrafía basada en quistes de dinoflagelados del Eoceno tardío - Mioceno del pozo Ombucta x-1, Cuenca del Colorado, ArgentinaBiostratigraphy based on Eocene-Miocene Dinoflagellate cysts from (YPF) ombucta X-1 borehole. Colorado Basin, Argentina
(Asociacion Paleontologica Argentina, 2000-12)
Dinoflagellate cysts are present in varying amounts allowing age interpretation for the section. Selected dinoflagellate cysts events, mainly last occurrences, suggest five age intervals: late Miocene to early Pliocene, ...
Bioestratigrafía basada en quistes de dinoflagelados de la Formación Cabo Peña (Eoceno terminal- Oligoceno temprano), Tierra del Fuego, Argentina
(Instituto Geológico y Minero de España, 2002-12)
In this paper we describe the lithostratigraphy and biostratigraphy of the Cabo Peña Formation in its type area of northern Tierra del Fuego. The Cabo Peña Formation consists mainly of siltstones passing upwards into silty ...
Middle Eocene Dinoflagellate cysts from Santa Cruz Providence, Argentina: Biostratigraphy and Paleoenvironment
(Elsevier, 2014-09)
The upper member of the Río Turbio Formation is a well-exposed marine Eocene unit at high latitudes in Patagonia, Argentina. It holds important information helpful to reconstruct regional climate and oceanographic patterns ...

Palaeoenvironmental Reconstruction of the Puerto Madryn Formation (Middle to Late Miocene), Northeast of Patagonia: Palynology, Nannofossils and StratigraphyReconstrucción paleoambiental de la formación Puerto Madryn (mioceno medio-tardío), Noreste de Patagonia: Palinología, Nanofósiles y Estratigrafía
(Asociación Paleontológica Argentina, 2019-05)
A 20 m-thick interval of the Puerto Madryn Formation was the subject of a multiproxy study, including sedimentological and stratigraphical observations as well as marine-derived amorphous organic matter, phytoclast, ...
New contributions to the palaeoenvironmental framework of the Los Molles Formation (Early-to-Middle Jurassic), Neuquén Basin, based on palynological data
(Springer, 2020-10-12)
Being the main oil-bearing basin of Argentina, the Neuquén Basin contains a well-documented stratigraphic record of continental and marine sedimentation during the Jurassic and Cretaceous in the western margin of Gondwana. ...
