My temporal emphasis is the latest Cretaceous (Maastrichtian 78-65 Ma) and Miocene 23- 5.3 Ma, intervals profoundly different to the modern world. These periods include the latest climate changes. I use macrofossil leaves and pollen fossil to understand past global changes and to evaluate ancient ecosystems, emphasizing in paleoclimatology; the behavior of floras and the evolution and diversification of plants
Principal Field areas include the subterranean coal mine in Guaduas Formation from Boyaca and Cundinamarca states of Colombia; Central Chile outcrops of Navidad Formation.
