Paleoendemic
Paleoendemic
an endemic species or genus of plants or animals that is characteristic of a single country or region. A paleoendemic is often native to the region and has existed for a long time. Such a plant or animal often is unrelated to other representatives of the surrounding flora or fauna. Examples of paleoendemics are the gymnosperm gingko (preserved only in eastern Asia) and the desman. The gingko is the only extant representative of a formerly extensive group of plants. The desman, which inhabits the Volga and Don basins, was widely distributed in the Tertiary. (SeeNEO-ENDEMICS.)
