Dinosaurs: understandably you may have questions. Questions like ‘just how formidable was the Tyrannosaurus Rex?’, ‘what was the largest dinosaur of them all?’, and ‘why does the pot-bellied Nothronychus look that weird?'.

Fortunately, palaeontologists have these answers ­­­– they’ve uncovered much about this intriguing group of reptiles that roamed the Earth 230 - 66 million years ago

 

Dinosaurs are a diverse group of reptiles[note 1] of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is a subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya and their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic.
