Something to work on soon...

I want to do some dinosaur paintings. I've been looking at some, and they all seem to have the dinosaurs walking in the dust. Yes, flowering plants, which only developed in the Cretaceous, could tolerate more dryness than other kinds of plants, but it still seems like if it isn't actual desert, there should be at least some signs of life. I mean, what is the point of painting a lone dinosaur (of a type they think were herd animals) next to conifers he can't reach the foliage of on an otherwise dusty, barren landscape?
