There are only a few clues in the rock record about climate in the Proterozoic con.
Much of our information about climate in the more recent periods of geologic history
comes from the fossil record, because we have a reasonably good understanding of
Line the types of environment in which many fossil organisms flourished. The scarce fossils
5) of the Proterozoic, mostly single-celled bacteria, provide little evidence in this regard.
However, the rocks themselves do include the earliest evidence for glaciation, probably
a global ice age.
The inference that some types of sedimentary rocks are the result of glacial activity
is based on the principle of uniformitarianism, which posits that natural processes now
