Also known as Coal beds 100
Where: Guajira, Colombia (11.2° N, 73.0° W: paleocoordinates 8.6° N, 59.8° W)
• coordinate stated in text
When: Cerrejon Formation, Middle Paleocene to Middle Paleocene (61.7 - 55.8 Ma)
• This age estimate is based on biostratigraphic correlations and has been described elsewhere (Jaramillo et al., 2007).
Environment/lithology: delta plain; sandstone and gray siltstone
•depositional sequence suggests paleoenvironments that range from coastal
•plains characterized by deltaic systems at the base of the sequence, to continental environments dominated by fl oodplains, swamps, and lagoons near the top of the formation ( Jaramillo et al., 2007 )
