With such huge diversity in both form and habits, what is it that makes a dinosaur distinct from a crocodile or a lizard?

Ben explores the stores in London’s Natural History Museum to meet the earliest known dinosaur and learns of the cataclysmic events that came about at the dawn of this incredible group of animals.

After millions of years as the underdog amongst much bigger, meaner animals, the end-Triassic mass extinction event gave the dinosaurs their chance to flourish... and boy did they grow big!

Ben meets some of the biggest animals to ever walk the earth, finds out how we know how big they got, and how and why they reached such huge sizes.

A discovery in China in the mid-nineties changed how we picture dinosaurs forever. It was the first fossil of a feathered dinosaur ever found and it finally proved unequivocally that birds are the direct decedents of dinosaurs.

Ben hears about an amazing discovery that sheds light on when, and why, feathers first evolved and what fossilised feathers can tell us about the colour of dinosaurs.

The fossilised tracks and traces made by living dinosaurs can give incredible insight into their behaviour. Ben discovers how some dinosaurs walked, what they ate, how they chose their mates, and how they cared for their eggs and young using their footprints, scrape marks, coprolites (also known as fossilised poo!) and nests.

Ben meets the Ichthyosaurs, Plesiosaurians, and the Pterosaurs (the skin-winged flying reptiles).

All highly specialised carnivores these rulers of the waves and air are often mistaken for dinosaurs - but were definitely not dinosaurs.

It’s only in the last decade that palaeontologists have finally agreed on the events that led to the demise of (most of) the dinosaurs - a huge asteroid strike in what we now know as the Yucatan Peninsular in Mexico.

Ben presents the evidence built up over the last 40 years. He also learns why birds might have been spared and what the fall of the dinosaurs meant for today’s most dominant group - the mammals.
