Geological timescale. Triassic period: 250â200 million years ago. Jurassic period: 200â145 million years ago. Cretaceous period: 145â65 million years ago. Dinosaurs roamed the planet for about 165 million years, during a time in the Earthâs history called the Mesozoic Era. It is difficult to imagine how long this was, until we compare it with ourselves: humans have lived on Earth for less than two million years. During the Mesozoic Era, the Earthâs landmasses changed dramatically, new seas were formed, and plants and animals evolved.
How Long Ago Did Dinosaurs Live: The Triassic Period. The Eoraptor, shown above, was one of the earliest dinosaurs. As weâve seen, the earliest estimate as to when dinosaurs appeared was around 243 million (243,000,000) years ago. Of course, dinosaurs didnât just appear out of thin air.
