The Newtonsaurus was a dinosaur which is believed to have lived in the late Triassic period. It is not yet described by any scientist and hence its existence is considered dubious. Its remains were discovered in the year 1899 and were classified under a different existing genus.
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.
