3.1.3 Searching by Timescale
The Time Scale Search allows you to specify a specific Age range in Ma and/or the name of a geological timescale for your search.
The Age [Ma] fields are pre-filled with the maximum possible values for contribution ages, from 0 Ma to 4550 Ma. This includes every possible date range. Modify the search values to search for a more specific age range.
The Time Scale field allows you to indicate one or more terms indicating a geological timescale name(s). Multiple search terms narrow your search, and should be separated by spaces or colons. Examples of Time Scale search values are Cenozoic, Serravallian, Tertiary, and Late Cretaceous.
