Prehistoric dinosaurs are a diverse group of reptiles that lived millions of years ago during the Mesozoic Era. They appeared roughly 230 million years ago and thrived until about 65 million years ago. Dinosaurs include both herbivores, like Triceratops, and carnivores, like Tyrannosaurus rex. They evolved unique features for their environments, such as powerful legs for running or armor for protection. Their extinction marked a major event in Earth's history, allowing for the rise of mammals. Our understanding comes from fossils, which give clues about their biology, behavior, and the ecosystems they inhabited.
