<< At the times in question the Sahara was a temperate climate, possibly
much like the American Midwest. My major objection is that dung beetles
rule Africa, and all piles likely to grow mushrooms will not remain
intact long enough to do so. An elephant dump turns into a sheet about 2
inches thick within 48 hours, and vanishes in about a week. Shroom
mycelium incubation to fruiting takes 2 weeks minimum.
Thats interesting, the only thing that can be said is maybe dung beetles
werent around 100,000 years ago. The theory is that mushrooms grew in
shorter and shorter supply until there was none left, maybe this is due to
the dung beetle.
