This is the latest version of the time scale, as revised and published in 2012.The Silurian was a period of increasing gastropod diversity in most gastropod clades, as part of the recovery from the end-Ordovician mass extinction. Species with high spires became more common, as did taxa with slits at their apertures (Fryda et al 2008: p. 261).

The Archean represents the time period from 4,000 to 2,500 Ma (millions of years ago).Falling atmospheric CO 2 levels led to cooling through the Eocene and the expansion of Antarctic ice sheets close to their modern size near the beginning of the Oligocene, a period of poorly documented climate. Here, we present a record of climate evolution across the entire Oligocene (33.9 to 23.0 Ma) based on TEX 86 sea surface …Pacific Ocean circulation, temperature, primary productivity, and chemistry have changed radically over the course of the Cenozoic. During that same period of time the Earth cooled from the extreme warmth of the early Cenozoic to the glacial conditions of the modern world.
