The Upper Cretaceous stratigraphic record of the Eastern Bogota Plateau and Llanos Thrustbelt of Colombia was studied in several outcrop sections and oil wells, leading to an alternative scheme of stratigraphic nomenclature and sequence stratigraphic interpretation. The Chipaque Formation (Cenomanian-Campanian) is overlain by the Guadalupe Group in the Bogota Plateau and by the Palmichal Group in the Llanos Thrustbelt. From oldest to youngest, the correlation between the subdivisions of these two groups is as follows: The Arenisca Dura Formation (Campanian) of the Guadalupe Group, corresponds to the Arenitas de San Antonio Formation of the Palmichal Group; the Plaeners Formation (Campanian-Maastrichtian) to the Lodolitas de Aguacaliente Formation; the Arenisca de Labor, the so-called Lutitas y areniscas finas and the Arenisca Tlerna Formations of the Guadalupe Group correspond to the Arenitas de San Luis de Gaceno Formation of the Palmichal Group. In turn, a lower part of the Guaduas Formation of the Bogota Plateau is equivalent to the Guaduas Formation of the Palmichal Group. The Palmichal Group is redefined by excluding the overlying Socha Inferior Formation from it, mainly because the Socha Inferior's lower limit is represented in some places by an unconformity. Additionally, the above mentioned formations are included now in the Palmichal Group. Major depositional environments shift according to sea level fluctuations of second and third order. The Chipaque Formation of the Bogota area is a second order (super)cycie where at least four third order sequences are circumscribed. Likewise, the Guadalupe Group and the Guaduas Formation aresupersequences that bear higher frequency sequences. A major erosion period, documented here in the Medina-1 well, cannibalized part of the Maastrichtian of the Palmichal Group. The youngest sequence studied is represented in its lower portion by the lowstand deposits of the Socha Inferior Formation.The Upper Cretaceous stratigraphic record of the Eastern Bogota Plateau and Llanos Thrustbelt of Colombia was studied in several outcrop sections and oil wells, leading to an alternative scheme of stratigraphic nomenclature and sequence stratigraphic interpretation.
