Humans have been studying the petrified remains of prehistoric animals for around 350 years and over that time we have often used illustrations to demonstrate our findings. 

This "dinosaur art" has evolved and changed countless times over the centuries as new information becomes available and new ideas emerge. 

In this PBS Eons video, Hank Green takes us back in time to see the evolution of dinosaurs through the eyes of the artists that imagined them. 

It is quite shocking to see how much our ideas have changed over the years and it makes you curious as to how much they will change in the future.
