BBC Online, BBC Education, London: The Essential Guide to Rocks (This animation was a collaborative effort between the BBC, Birkbeck College London, and H & K Netcoms): Britain's Rocky Past. An animation and interactive timeline featuring 4600 million years of dramatic continental drift, fossil life and rocks, including simplified UK geological maps (Click "Rock map"). You'll need the Shockwave Flash plugin. Click " Go to animation".

! International Commission on Stratigraphy (ICS): Timescale. This edition of the International Stratigraphic Chart is intended to give a clear picture of the present state of the art in chronostratigraphic subdivisions of geological time, mentioning only units recommended for international use. Updated to summer 2001, including the current status of formal and proposed chronostratigraphic units. Download a PDF (Adobe Acrobat) version of the International Stratigraphic Chart.

Andrew MacRae: Radiometric Dating and the Geological Time Scale. Circular Reasoning or Reliable Tools? This TalkOrigins site (a Usenet newsgroup devoted to the discussion and debate of biological and physical origins) discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale.

William L. Newman and Kathie Fraser, U.S. Geological Survey (USGS): Geologic Time. Two scales are used to date these episodes and to measure the age of the Earth: a relative time scale, based on the sequence of layering of the rocks and the evolution of life, and the radiometric time scale, based on the natural radioactivity of chemical elements in some of the rocks (a list of group of rocks and materials that have dated by various atomic clock methods).
