I know nothing about taxonomy. But here is my take on it.
Biomass is rughly (very rughly) represented by thickness.
Biomass should be determinable from the fossil record, but I just don't have the time
for it.
Time is rughly represented by polar distance from lower center.
Several sharp mass extingtions, such as 65 million years ago, are not shown.
