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.
Dinosaurs walked the Earth for an incredible 165 million years. They first appeared in the late Triassic Period, before diversifying to dominate the planet, and become the largest land animals to have ever lived. However, 65 million years ago, the reign of the dinosaurs was to come to an abrupt end. An event so monumental occurred that it changed the shape of our planet forever. Evidence points to a giant asteroid which smashed into the Earth, leaving a crater nearly 200km wide.
