- Abstract
In the course of life development, just a small number of key evolutionary events were registered that inspired global biosphere changes. The explosive development of terrestrial vegetation and the appearance of forest ecosystems in the Devonian period was one of such events. Land colonization started by bryophytes, and their ancestors required the appearance and development of various root systems. Roots evolved separately and independently in several main directions, rapidly expanding their functionality. Numerous paleosol horizons and their complexes were studied in the middle reaches of Tsilma River on the Middle Timan Ridge in the red-colored mid- and upper Devonian sediments. The palynological data testified to highly diverse terrestrial flora in this area. The ancient soils contained in situ roots of various types. This work was aimed at morphological description of the discovered root systems. At present, the taxonomy of Devonian root systems is at the stage of primary data accumulation. As a result of the studies, three morphological types of root systems belonging mainly to grass-like plants have been identified in paleosols. There are no descriptions of such objects in paleobotanical literature. Morphological types of root systems are correlated with geomorphological features of the studied territory.
