- Аннотация: The Middle Longcraig Limestone (late Visean) at Catcraig, Scotland, is densely covered with large (about 1 m in diameter) hollows, whichare surrounded by numerous fossilized roots. The latter represent the positions of tree-sized plants belonging to a fossil forest. This paper aims toreconstruct its ecology based on paleosol properties, size and spatial distribution of root-casts, rooting system morphology and characteristics ofcoalified plant remnants. The obtained data are consistent with the supposition that the Visean peat wetland forest of Catcraig represents a Cordaitaleandominated community composed of mono-sized, most probably, even-aged giant trees. The peaty paleosol (Histosol) contains pyriteand siderite, indicating reducing and acidic conditions, whilst the abundant presence of gypsum testifies periods of elevated salinity. The adaptationof trees to such conditions is supported by morphologically evident large root mass (typically more than 1000 individual roots per cast).Good preservation of plant tissues in peat, in addition to other paleosol and rooting system characteristics allow us to conclude that the treesoccupied seacoast settings or lagoons, which were not permanently flooded.
