元古宙（Proterozoic，符号PR），又称元古代、原生代。Proterozoic属希腊字源，意为早期原始生命。元古宙同位素年龄从25亿年—5.7亿年左右，共经历19亿 ...

It is unclear why atmospheric O2 remained at low levels for >1.5 billion years following the Great Oxidation Event. Here, the authors show that tectonic recycling of previously accumulated ...

Archean and Proterozoic History Reading: Chapter 8 This is a hard chapter to read. There's a lot of names and regional detail that we are not going to deal with. Try to filter out as much as you can ...

Life Story - the Proterozoic era A look at life in the pre-Cambrian era, more than half a billion years ago.

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago ...

A study suggests that around 1 billion years ago, photosynthetic primary producers were likely too small to support the development of animal ecosystems.

During the Proterozoic era, oxygen produced by photosynthesizing bacteria collects in the oceans and then in the atmosphere. Iron present in exposed rocks reacts with this oxygen, and rust colors ...

The Proterozoic Eon is also called the Cryptozoic ("age of hidden life"). About 2.5 billion years ago, enough shield rock had formed to start recognizable geologic processes such as plate tectonics.
