Corals of the genera Lytvophyllum and Thysanophyllum from the Lower and Middle Carboniferous of the Urals
Abstract
The genus Lytvophytlum Dobr. belongs to the group of rare, very few and therefore poorly studied corals. So far, only two of its species have been described in the literature - the type genus L. tschernowi (Soshk.)from the Upper Carboniferous and Lower Permian of the Urals [Soshkina et al., 1941] and L. dobrolyubovae Vass.from the boundary layers of the Lower and Middle Carboniferous of Donbass [Vasilyuk, 1960]. In addition, coral finds at the base of the Middle Carboniferous of the Urals, identified by I. I. Gorsky in 1938 as L. tschernowi Var. antiqua Gоr. msc.. were also known. mention of which is contained in the works of I. I. Gorsky [1948] and V. D. Fomichev [1953]. Unfortunately, this form by I. I. Gorsky was not published.
