Popis:	The existence of an impact structure in northern Yucatan has been inferred based primarily on gravity and magnetic studies (Figure 1). This impact structure has been directly related with the massive biota extinction at the transition from the Cretaceous to the Tertiary (K/T) due to the global climatic changes induced by the impact of a major meteorite. At present, the available studies confirm both its existence and its association with extinction of the dinosaurs. Even if the existence of an impact structure in the subsurface in northern Yucatan has achieved near consensus, the subsurface features of this impact structure remain to be established. Independent studies have produced different conclusions about its type.
