The Paleobiota of the Latah Formation encompasses both floral and faunal elements preserved in temporary lacustrine environments formed between eruptive phases of the Columbia River Basalts in central to east Eastern Washington and central to north Idaho. The Latah Formation is centered around the greater Spokane area, with a western extent outcropping at Grand Coulee and the eastern margins as far southeast as the area of White Bird, Idaho.[1] Dating of the core Spokane sites is based on the host Grande Ronde Basalts which give a 16.5 to 16.1 million years ago age range The Clarkia fossil beds lagerstätte site are slightly younger, being interbedded in the Wanupum Basalts Priest Rapids Member with an age constraint of 16.1 to 15.9 million years ago,[2] or Early Barstovian in age.[3]
he intermittent lakes were surrounded by a temperate ecosystem that was mesophytic in nature, and hosting a diverse flora with plants that are still native to the region and others now restricted to other areas of the globe. There is a small element of the flora that consists of fully extinct genera that are unique to the time and region.[2] Based on work from sampling around Mica, Washington a diverse assembly of diatoms and algae.[4] The known fauna of the formation is smaller than the flora, with most taxa being insect species[5] though one unnamed Sciuridae fossil was described in 2018,[3] and fish belonging to the salmonid, cyprinid, and centrarchid groups are known.[6] Preservation varies from carbonized comapressions at most sites to exceptional organic preservations in some parts of the Clarkia area localities where original organic material is preserved down to living coloration and possible ancient DNA fragments.[7] Upper layers of the Clarkia deposits have been recorded with modern fungi actively feeding on the ancient organic material of the fossils as a food source.[7]
Plants
The initial taxonomic work on the flora was undertaken by Frank Knowlton with assistance from diatom specialist Albert Mann and bryologist Elizabeth Britton.[8] Their combined work was published as a supplemental chapter to the initial 1926 descriptive work by Joseph Pardee and Kirk Bryan. After Knowltons death in November 1926, his revision of the Latah flora was taken over by Edward W. Berry who also erroneously included strata of the much older Klondike Mountain Formation around Republic, Washington.[9] This error was noted and corrected in later works by Roland W. Brown.[10] Ralph W. Cheney and Daniel I. Axelrod broke the Latah into four major florules, Grand Coulee and Spokane in Washington plus Coeur d'Alene and White Bird in Idaho, while noting several "miscellaneous" sites as well.[1] Modern works have concentrated more on single taxa and certain florules.[2]

Algae
An initial survey of Latah Formation diatoms was conduced by Albert Mann at the behest of Frank Hall Knowlton. Based on sample material recovered from a well 0.25 mi (0.40 km) west of Mica, Washington, itself southeast of Spokane, Mann identified a large number of diatomaceous species, including 10 new species. Mann noted the diatoms appear to have lived under stressed conditions caused by caustic water, with many of the specimens showing malformed shapes or blurred ornamentations. The typical cause of this in diatoms is a high concentration of dissolved mineral salts in the water body.[4]
