relictual

I also believe that the distribution of "Aegean-type words", that is parallel to the spread of Aegean languages, is a result of a secondary expansion: Once the Cretan and Cypriot civilizations have reached the point of urban revolution (thanks to Egyptian cultural influence), a spreading of the (previously isolated and relictual) Aegean languages happened, all across the Aegean Sea, onto the Greek and Anatolian coast.

This ancient mesic forest type was formerly widespread in the Northern Hemisphere and is now represented by relictual ecosystems in eastern North America and eastern China.

In Malawi, this deforestation is particularly pronounced, as all that remains of the once extensive mid-altitude montane forests are small relictual groves used as graveyards by local people.

For example, populations of relictual Gondwanan conifer genera, now known only from Tasmania, i.e. Athrotaxis, Diselma, Microcachrys, are present and best represented in alpine moorland and rain forest communities.

Fun facts about the osage orange: it's key dispersal agents were probably north american megafauna horses, mastodons, ground sloth etc. and it's relictual distribution when Europeans arrived may have been due to the extinction of the megafauna some millenia before.

The Toomba and Undara flows of the Nulla and McBride sub-provinces harbor cave-adapted biota, similar to the cave systems of Chillagoe and Clarke River, providing refuge for specialized cave faunas and relictual rainforest faunas.

Land snails and spiders are well-represented and contain a number of relictual and ancient taxa, many with disjunct relatives in the forests of eastern Asia.

Many of the relictual species that survive in these forests are extinct on the nearby continents.

Although there is evidence that the grasslands found among forest patches today were present during the Holocene, the relictual nature of forests within grassland has been attributed to the destructive activities of man in the relatively recent past (100 to 300 years).

Van Wyk suggests that reduced competition on unfertile substrata allowed this relictual flora to persist.
