Abstract A palynological study of the Cerrejon Formation was conducted in order to date the formation and understand the floristic composition and diversity of a Paleocene tropical site. The Cerrejon Formation outcrops in the Cerrejon Coal Mine, the largest open cast coal mine in the world. Two cores (725 m) were provided by Carbones del Cerrejon LLC for study. Two hundred samples were prepared for palynology, and at least 150 palynomorphs were counted per sample where possible. Several… 

Palynological Evidence for the Paleoenvironmental History of the Miocene Llanos Basin, Eastern Colombia

The distal Llanos foreland basin was influenced by subsidence events since the Cretaceous until the Pliocene. Although this area has been extensively explored and is considered a potential oil

The Pliocene–Pleistocene Palynology of the Negro River, Brazil

ABSTRACT Palynological studies in central Amazonia are scarce, especially those concerned with resolving the age of sedimentary deposits. A recent opportunity allowed the stratigraphical and

Menispermaceae from the Cerrejon Formation, middle to late Paleocene, Colombia.

One of the most common leaf morphotypes of the Cerrejón flora (middle-late Paleocene, ca. 60-58 Ma), Guajira, Colombia, that contains one of the oldest records of neotropical rain forest floras is studied, suggesting a possible affinity with the pantropical angiosperm family Menispermaceae.

Palynology of the Middle Miocene—Pliocene Novo Remanso Formation, Central Amazonia, Brazil

Abstract. In order to reassess and amend previously published palynological data drawn from the Novo Remanso Formation, central Amazonia, we revisited the organic-rich samples from their work using

Late Paleocene fossils from the Cerrejón Formation, Colombia, are the earliest record of Neotropical rainforest

Cerrejón megafossils provide strong evidence that the same Neotropical rainforest families have characterized the biome since the Paleocene, maintaining their importance through climatic phases warmer and cooler than present.

Palms (Arecaceae) from a Paleocene rainforest of northern Colombia.

The fossil fruits and inflorescences of the Cerrejón Formation are among the oldest megafossil records of these groups and demonstrate that the divergence of the Cocoseae was more than 60 Ma, earlier than has previously been thought.
