Late Cretaceous through Cenozoic Paleoenvironmental History of the Bagua Basin, Peru: Paleoelevation Comparisons with the Central Andean Plateau
Published 2022-06-01“…We present new δ<sup>18</sup>O and δ<sup>13</sup>C signatures of pedogenic carbonate nodules from paleosols in the Campanian–Maastrichtian Fundo El Triunfo Formation and in the upper Eocene–middle Miocene Sambimera Formation to reconstruct the isotopic composition of paleo-meteoric water and the floristic biome. We compare these results to modern isotopic values from a newly obtained modern water transect to interpret the environmental evolution of this area and its relationship with the neighboring Eastern Cordillera. …”

Published 2012-12-01“…Early stages were dominated by typical pioneer species but species of mature forests were present throughout the chronosequence, and therefore the species plant distribution between stages may be explained by the initial floristic composition model. Because sites from all stages had similar number of species, our study does not support the intermediate levels of disturbance hypothesis. …”
