Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
The Jurassic (/ dʒ ʊ ˈ r æ s ɪ k / juurr-ASS-ik [2]) is a geologic period and stratigraphic system that spanned from the end of the Triassic Period 201.4 million years ago (Mya) to the beginning of the Cretaceous Period, approximately 143.1 Mya.
The Indian fossil record of dinosaurs is good, with fossils coming from the entire Mesozoic era – starting with the Triassic period (a geological period that started 251.9 million years ago and continued till 201.3 million years ago), to the Jurassic period (201 million years ago to 145 million years ago) and Cretaceous period (from 145 ...
The dinosaur lived 150 million years ago in the late Jurassic period, making it millions of years older than the terrifying Tyrannosaurus rex that roamed the Earth some 66 million to 68 million ...
Buckland, like others at the time, did not grasp how long ago dinosaurs lived, believing Earth to be only a few thousand years old. Scientists now know Earth is about 4.5 billion years old ...
Dinosaurs evolved partway through the Triassic period of the Mesozoic era, around 230 Ma (million years ago). At that time, the earth had one supercontinental landmass, called Pangaea , of which Europe was a part.
The dinosaur lived 150 million years ago in the late Jurassic Era, making it older than Tyrannosaurus rex — which lived 66 million to 68 million years ago. Researchers discovered the bones in ...
