Asteroid that wiped out the dinosaurs allowed flowers to thrive in a post-apocalyptic world



The giant asteroid that snuffed out the dinosaurs at the end of the Cretaceous period (145 million to 66 million years ago) left flowers relatively unharmed, and the blooms thrived in the aftermath, a new study has found.

Earth lost three-quarters of its species, including all non-avian dinosaurs, when an asteroid struck Mexico’s Yucatán Peninsula 66 million years ago. Scientists call this cataclysmic period the Cretaceous-Paleogene (K-Pg) mass extinction event.
