Oribatid mites are known as fossils back to the Middle Devonian period and Early Ordovician. Oribatid mites are known as fossils back to the Middle Devonian period and Early Ordovician. Oribatid can also be found, like beetle fragments, in interglacialand pre-Quaternary sediments and in different types of buried soils.

marine and brackish water littoral sediments, marine and brackish water littoral sediments, saltmarshes, as part of lake ecosystems, bogs and fens, all types of soils, arboreal habitats. Past shifts in oribatid assemblages can hopefully be used to reconstruct environmental variables such as temperature, lake chemistry, ice cover, succession of trees and lake-level fluctuations.

Reconstructions The genus Hydrozetes occurs in most lakes, tarns, bog pools and even in very wet fens where they often are found in great densities. They may be more abundant in eutrophic than in oligotrophic waterbodies (Bennike, 2000). Oribatid mites could help reconstruct the arrival and possible succession of trees, some may even be associated with only a single tree/shrub genus or even a single or a few species. For instance, Dentizetes ledensis is so far known only from leaves of Ledum groenlandicum (Behan-Pelletier, 2000). In tree ecosystems, oribatids are often associated with bark, epiphytic lichens and mosses.
