Late Paleocene fossils from the Cerrejón Formation, Colombia, are the earliest record of Neotropical rainforest. Proceedings of the National Academy of Sciences, USA 106 : 18627 – 18632.
• The Cerrejón endocarp fossils (CJ85-ING-1412 to CJ85-ING-1414) were found along with angiosperm leaf remains in an extensive gray siltstone bed around 60–90 cm thick that was deposited in a swampy-lacustrine environment. The local flora was dominated by Araceae, Arecaceae, Fabaceae, Lauraceae, Malvaceae, Zingiberales, and several unidentified ferns.
