Whenever someone mentions dinosaurs and you imagine them, what colors are they in your head? 

The answer will most likely depend on when you were born and attended school. 

Throughout most of the 20th century we imagined dinosaurs as drab shades of green and brown, much like the modern lizards that we are used to.

Watch the video below to learn more about these discoveries and what they mean.
