The predominantly shale and siltstone formation, with sandstone beds intercalated, dates to the Paleogene period; Upper Paleocene to Lower Eocene epochs, with an age range of 61.66 to 52.5 Ma, spanning the Paleocene–Eocene Thermal Maximum.

[2] The Bogotá Formation consists mainly of grayish-red, locally purplish, commonly greenish-gray, generally poorly stratified mudstone and silty claystone.

[6] Additionally, macroflora of Palaeophytocrene hammenii, named after Dutch botanist Thomas van der Hammen,[7] and pollen of Foveotriletes margaritae, Proxapertites operculatus and Foveotricolpites perforatus have been found, used for dating the formation.

[12] The finds of iguanians, including the fossil record of hoplocercines, and boine, caenophidian, and ungaliophiine snakes, indicate a tropical forest environment, present just before the Early Eocene Climatic Optimum (EECO).

[13] The faunal distribution has been correlated to the Carodnia-, Amphidolops-, and Wainka-bearing Peñas Coloradas Formation of the Golfo San Jorge Basin in Patagonia, Argentina.
