I just ran across this really cool Carboniferous Forest Simulation, which lets you explore a small area of a Carboniferous forest, complete with helpful info when you click on things! It especially piqued my interest because my evolution! exploration game is also more or less set in the Carboniferous, if only an alternate-reality version of it. The Carboniferous Forest Sim is only in Alpha right now, so everything isnt implemented yet, but its very promising! Check it out!
