Summary
| Description |
English: The geologic time scale proportionally represented as a log-spiral. Some key events in Earth's history are marked on the diagram, including major extinction events, global scale glaciations, the initiation of permanent atmospheric oxygen, the formation of the moon, and the formation of Earth's magnetic field. The outer spiral arcs show components of the evolution of life on Earth.
Ma=Megaannus (unit of 1 million years) This version uses the official International Commission on Stratigraphy colour scheme for the time scale and the scientific colours batlow colour scheme for life evolution. It has black text in transparent regions for use on light backgrounds. All text is converted to paths to preserve appearance. |
