Abstract
The first Paleocene pollen species were described in van der Hammen, 1954. One species was redescribed in van der Hammen, 1956.
The Paleocene’s species associations and climatic changes were described and discussed in van der Hammen, 1957a, and the palynological correlation of sediments of this age in van der Hammen, 1957b.
New species found in the Paleocene are described here, and those found but previously described from the Maastrichtian or Eo-Oligocene are mentioned. This article thus forms a catalog of the main Paleocene pollen species from Colombia.
Almost all holotypes were found in the samples used for the general diagram (van der Hammen, 1957a).
The terms used in the following descriptions almost all correspond to the definitions of Iversen & Troels-Smith, 1950. Therefore, the systematic nomenclature published in van der Hammen, 1956b is used here.
All samples were prepared by Schulze treatment at the Paleobotany Laboratory of the National Geological Survey.
