When mushrooms ruled the world - when was that exactly?
Well about 400 million years ago, when they first appeared and began the work of breaking down rock into soil, thus laying down the basis for life on the planet as we know it.
Also evidence of giant mushrooms is found in the fossil record in the form ofprototaxites, which have been discovered this century in Saudi Arabian locations.
The fantastical giant mushrooms of sci-fi and fantasy movies may not be so fanciful after all.
