Chicxulub, Yucatan Peninsula, Mexico. Sunlight breaking through clouds with birds flying over a beach with fishing boats on the Gulf of Mexico at the village (puerto) of Chicxulub on the Yucatan Peninsula in Mexico. This village gave its name to the Chicxulub Crater, a 180-kilometre-wide asteroid impact crater that formed 66 million years ago. The impact occurred close to this location. It triggered a mass extinction event that was responsible for the extinction of the dinosaurs and 75 percent of life on Earth. Photographed in May 2016.
