What was the environment like in the Jurassic period?

I am not positive, but when you look in pictures and illustrations you usually see grassy plains, mostly rainforests, and sometimes dry cracked deserts. . And you have to think about man-made damage, there weren't any people to destroy land for uses, so the plants and living things, even nonliving organisms were untouched and very overgrown. So if this is for a school report or something, it would probably be the safest thing to go with rainforests.
