Dinosaurs Giants of the Past

Dinosaurs were reptiles that dominated Earth for 165 million years, first appearing around 230 million years ago. They varied in size and diet, with herbivores, carnivores, and omnivores adapting to diverse environments. Most went extinct 65 million years ago due to a catastrophic asteroid impact, but birds are their modern descendants. Studying dinosaurs and their fossils helps us understand Earth's biological history and the evolution of life.
