The Full Story
Grasses are believed to have originated around 66 million years ago, close to the end of the age of dinosaurs. Early grass fossils are rare, but molecular evidence and fossil grains suggest a late Cretaceous origin. Grasses later transformed Earth’s ecosystems, especially after the extinction of non-avian dinosaurs. Their spread eventually led to grasslands, which became important habitats for grazing animals.
