Introduction

Topic Overview

Over 200 million years ago, terrestrial and oceanic reptiles known collectively as Dinosaurs appeared and dominated Earth's fauna for approximately 135 million years. Fuelled by lush forests, warm temperatures and a conducive atmosphere, the diversity of clade Dinosauria ranged from rodent size carnivores, building size herbivores, seafaring goliaths and airborne hunters. Contemporaneous for much of their reign with birds and mammals, environmental changes conspired to tilt the balance of power towards these competitors ending their dominance and ultimately leading to their extinction. What do we know about the epoch in which they lived? What is the appeal of their enduring legacy and will we ever see their like again?
