A sandbox game I'm running is now underway and I want to stress a lot of the natural world, so before pulling out nature books and making up stats for lots of offbeat animals and prehistoric mammals, I was hoping someone already did that in the OGL community.

Are there any monster manual like books that greatly expand on the natural world?
