The Cretaceous is the youngest part of the Mesozoic Era. The Triassic period had started 227 million years ago and ended 22 million years later. When the Triassic period ended the Jurassic period started. The Jurassic period started 205 million years ago and ended 61 million years later. After the Jurassic period came the Cretaceous period. The Cretaceous period started 144 million years ago and ended 79 million years later. The dinosaurs have been alive ever since the beginning of the Triassic period and are still alive today. But the dinosaurs that are alive to this day are the evolve creatures of those in the past.
