From slow, plant-eating giants to fierce scavengers and hunters, dinosaurs dominated the land for over 160 million years.
Prof Paul Barrett, Natural History Museum dinosaur researcher, has examined the evidence for how five of the most popular dinosaurs lived.
This slow-moving plant-eater used spikes on its tail to fend off would-be predators. The jury is still out on what the spiny plates on its back were used for.
An infamous meat-eating predator. Look at the evidence as to whether Tyrannosaurus hunted in packs or alone.
A cast of a Diplodocus skeleton takes pride of place in the Museum's Hintze Hall. What did this giant look like and how did it hold its enormous neck?
This small meat-eater was one of the earliest dinosaurs. It was fast and agile and would have fed on animals like small reptiles and insects.
