Lithology and environment
| Primary lithology: | tabular,gray lithified muddy,silty siltstone |
| Includes fossils? | Y |
| Lithology description: 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. | |
| Environment: | fluvial-lacustrine indet. |
