  2. Template:Timeline geological timescale - Wikipedia

    en.wikipedia.org/wiki/Template:Timeline...

    The following five timelines show the geologic time scale to scale. The first shows the entire time from the formation of the Earth to the present, but this gives little space for the most recent eon. The second timeline shows an expanded view of the most recent eon.

  3. Template:Geological timeline - Wikipedia

    en.wikipedia.org/wiki/Template:Geological_timeline

    |labels= optional - Sets geological time labels to be displayed (era, period, epoch, age) Period options: cenozoic not functional - displays entire Cenozoic timescale; quaternary not functional - displays Quaternary timescale; neogene not functional - displays Neogene timescale; paleogene not functional - displays Paleogene timescale

  4. Geologic time scale - Wikipedia

    en.wikipedia.org/wiki/Geologic_time_scale

    The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).

  5. Timeline of natural history - Wikipedia

    en.wikipedia.org/wiki/Timeline_of_natural_history

    Geologic time is the timescale used to calculate dates in the planet's geologic history from its origin (currently estimated to have been some 4,600 million years ago) to the present day. Radiometric dating measures the steady decay of radioactive elements in an object to determine its age. It is used to calculate dates for the older part of ...

    It is recommended not to use this parameter unless there is ongoing dispute involving the time span's boundaries. See Template:Geological range for more information. top_bar_ref Inserts a reference into the text above the timeline bar. time_start The time when the geologic time span starts, in millions of years. time_start_prefix

    en.wikipedia.org/wiki/Category:Geological_range...

    If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Geological range graphical timeline templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Geological range graphical timeline templates]]</noinclude>

    Before I made this template sortable the start of the Eoarchean is exactly 4 billion years ago. Start dates for eras in the Hadean is taken from Geological history template. So Cryptic starts 4567mya, Basin Groups 4.5bya, Nectarian 4.3bya, and Early Imbrian 4.1bya. Now to make this template become sortable efficiently The rowspan and major ...

    To change this template's initial visibility, the |state= parameter may be used: {{Geological history of Earth | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Geological history of Earth | state = expanded}} will show the template expanded, i.e. fully visible.
