New research suggests that grapes might not have thrived if dinosaurs hadn’t gone extinct 66 million years ago. The asteroid impact that wiped out dinosaurs allowed other species to flourish. Fossilized grape seeds, found in Colombia, Panama, and Peru, dating from 19 to 60 million years old, reveal how grapes spread globally post-dinosaurs. One seed is the oldest grape family plant found in the Western Hemisphere. This discovery helps scientists understand plant evolution and the spread of grapes after the dinosaur extinction.
