Palynology, Paleofloras and Paleoenvironments
Micropaleontology, 1961Changes in diversity offossil polospore assemblages, traced through sedimentary series, are interpreted as having evolutionary and environmental significance in terms of the floras that produced them. Congruent corresponding changes in the frequency of first and last appearances lend support to these hypotheses.

Paleoenvironment, Tectonics, and Paleobiogeography
2018The Earth experienced dramatic transformations during the Cenozoic, with changing sea levels, climate, and tectonic events having major influences on the global biota. In South America, loss of the connection between Patagonia and Antarctica, Andean orogeny, and formation of the Isthmus of Panama defined the continent, as we know it today. These events

Interpreting Paleoenvironments with Microfossils
The Paleontological Society Papers, 1996One of the basic tenets of geology is the present is the key to the past. In the present context, this simply means that if we document the distribution of organisms today and have some degree of understanding of what combination of environmental variables controls those distributions, then we can use this information to reconstruct past environments ...

Miocene Marine Transgressions: Paleoenvironments and Paleobiodiversity
2017Two major marine transgressions covered part of Patagonia during the Miocene and both are recorded in the Peninsula Valdes region. The older (early Miocene) is represented by the volumetrically scarce outcrops of the Gaiman Formation, composed by shelf mudstones and fine sandstones.

Paleoenvironment and Human Settlement in Japan and Korea
Science, 1977The climate of Japan changed from cooler than present (12,000 to 11,000 years ago) to warmer than present (8000 to 4000 years ago) to cooler than present (4000 to 1500 years ago). The height of the warm period coincides with the Jomon marine transgression, which flooded coastal lands and invaded river valleys.
