A large body of scientific evidence
now exists that support the hypothesis that a major
asteroid or comet impact occurred in the Caribbean
region at the boundary of the Cretaceous and Tertiary
periods in Earth's geologic history. Such an impact
is suspected to be responsible for the mass extinction
of many floral and faunal species, including the
large dinosaurs, that marked the end of the Cretaceous
period. Until now, the remains of such an impact
crater have escaped detection. The geohydrological
feature (Cenote Ring) of Northwestern Yucatan, was
discovered through NASA Ames Remote Sensing technology,
and represents a prime candidate for the impact
site of a global catastrophic event.
