What´s next? • Re-sampling of locations from Maync (1949) and Petters (1954) • Sampling of more Barremian outcrops in Eastern Cordilleran (e.g. Santander) • Sampling of lower Cretaceous outcrops in Central Cordilleran (Quebradagrande Complex) • Sampling of lower Cretaceous outcrops in northern Guajira (Yuruma Group) • High resolution biostratigraphy? (e.g. isotopes)
