Forty-seven rock samples from the stratotypes of three upper Paleogene formations–
Prussian, Palvé, and Kurshskaya formations–were collected from the biggest amber deposit …

Abstract The Silurian–Devonian transition played a crucial role in the development of early
terrestrial ecosystems due to the rapid diversification of early vascular plants. However …

The Hirnantian “glacial horizon” has been recognized across the Central Andean Basin
(Puna, Cordillera Oriental, Sierras Subandinas and Sistema de Santa Bárbara) in …

Assemblages of cryptospores were reported and detailed for the first time from the Upper
Ordovician from Brazil. These assemblages were recovered from diamictites and shales with …

This is an exhaustive analysis of the palynomorph assemblages, organic-walled marine
phytoplankton and miospores from the Tucunuco Group. This group includes the La Chilca …

The palynological information of the Paso Aguiar Formation (Paraná Basin, Uruguay) is
scarce, and the overlying Yaguarí Formation has been hitherto considered as barren. In this …

The palynological assemblages of the Talacasto and Punta Negra formations, from the
Argentinean Precordillera, were analysed. Marine phytoplankton is dominant in both …

Devonian deposits in northwestern Argentina were historically studied with stratigraphical
purposes, since these layers conform the source rocks of the producing basins of the region …

This study is concentrated on Ludlow (to Pridoli?) miospores from the Los Espejos
Formation at the Quebrada Ancha locality, Central Precordillera, San Juan Province …

The distribution and diversity of marine palynomorphs, such as acritarchs and chlorophytes,
and terrestrial palynomorphs, such as miospores, are controlled mainly by …
