The Subject Thesaurus is a collection of controlled terms used to index subject concepts
ZR on CD including geographical and paleontological terms.
For geographical terms, there are two hierarchies. Controlled terms representing zoo-
geographical regions, countries, states, oceanic islands or similar political designations
and inland freshwater systems spanning more than one country are included in the
Land and Freshwater Zones hierarchy. The Marine Zones hierarchy includes oceans and
seas and is used to index all marine localities.
Paleontological terms are included in a single hierarchy, representing the following
main geologic time periods: Caenozoic, Mesozoic, Palaeozoic and Precambrian. The
paleontological hierarchy is presented in reverse chronological order (from the most

Common terms representing broad groups of organisms. For example, searching
