Integration of regional stratigraphic relationships with data on sediment accumulation,
provenance, paleodrainage, and deformation timing enables a reconstruction of Mesozoic …

We review geological evidence on the origin of the modern transcontinental Amazon River,
and the paleogeographic history of riverine connections among the principal sedimentary …

The end-Cretaceous event was catastrophic for terrestrial communities worldwide, yet its
long-lasting effect on tropical forests remains largely unknown. We quantified plant …

Using the most comprehensive fish occurrence database, we evaluated the importance of
ecological and historical drivers in diversity patterns of subdrainage basins across the …

This review explores the evolution of extant South American tropical biomes, focusing on
when and why they developed. Tropical vegetation experienced a radical transformation …

An alternative hypothesis concerning the paleoecological and paleoenvironmental
depositional conditions of the Crato Konservat-Lagerstätte (CKL), Crato Formation, Aptian …

Abstract In the Miocene (23–5 Ma), a large wetland known as the Pebas System
characterized western Amazonia. During the Middle Miocene Climatic Optimum (c. 17–15 …

The unparalleled biodiversity found in the American tropics (the Neotropics) has attracted
the attention of naturalists for centuries. Despite major advances in recent years in our …

Integration of several geologic lines of evidence reveals the prevalence of a lowland trans-
Andean portal communicating western Amazonia and the westernmost Andes from at least …

Taxonomic resolution is a major challenge in palynology, largely limiting the ecological and
evolutionary interpretations possible with deep-time fossil pollen data. We present an …
