This showed life beginning with the Silurian system, which it described as "a marine deposit of vast extent containing abundance of marine organic remains. Together, these extinctions may have removed about 85 percent of species of marine animals.They said "the epithet carboniferous is of obvious application to this series".Henry Shaler Williams (1891) proposed Pennine System as the name for the Carboniferous.It is suggested that analysis of sedimentary pyrite from the Belingwe sedimentary basin in Zimbabwe may provide evidence for bacterial reduction at this date.2,500,000,000 to 542,000,000 years ago The Proterozoic Eon: the most recent part of the Precambrian Supereon.
