It always staggers me when I remember that for roughly sixty million years during the Carboniferous Period, there were trees but no microorganisms capable of decomposing them.
Just sixty million years of branches falling off and trees falling down and… just sitting there on the ground, not rotting at all.
Note that although species can be described as tree-like, they didn’t quite look like modern trees do. Also, much of the world was swamp, and much of the dead plant material sank into these bogs and decayed into peat.
The amount of CO2 trapped during this period caused the atmosphere to be around 35% oxygen. This allowed life with inefficient respiratory systems to grow much bigger in size without suffocating, mainly insects. Think woodlice 6 feet long, spiders the size of dogs, millipedes as big as cars, and dragonflies as big as eagles.
I LOVE the thought of a world-covering swamp with pseudo-trees and giant fucking bugs. Such a stimulating thought. I’d love to explore and see it.
but imagine you’ve just gotten use to living on a moss planet over the past 40 million years, and now all of a sudden you walk outside and all the moss is gone
The ocean was purple once, and another time the only thing taller than little bushes were twenty foot tall mushrooms shaped like asparagus
Seriously?! 80ft horsetails? I knew they were a prehistoric plant that can grow through asphalt but had no idea they got that big
Fortunately, there was no thinking until a very long time after that.
Well, not by life indigenous to Earth, anyway.
