Like many of you, I follow the page "I fucking love science" on facebook. This caught my eye, had a quick read through the link and sounded pretty cool. Obviously it reminded me of Zangarmarsh instantly. What the article says isn't set in stone exactly (well, excluding the fossil was for millions of years...) and there's no confirmation they were giant shrooms but there appears to be some thought about it. Seems pretty cool to me, thought you guys might like it
