Abstract: 

Most of the specimens of Corynepteris collected from the Dobrudzha Coalfield sequence are small parts of pinnae. Two species – C. angustissima and C. coralloides predominate. The habitat of Corynepteris had been studied for a long time. The genus occurs in several units of clastic sediments deposited under fluviatile conditions across the prospected part of the depression, but is absent above the coal seam m9 (middle Bolsovian). When the swamp conditions were restored briefly (coal seams n1–n4) or for a longer time (Gurkovo Formation) the genus did not resettle in the depression. The nearest basin with the genus Corynepteris presented at that time is in the Czech Republic, more than 800 km away, which was too far for an effective reintroduction of the genus to the Dobrudzha Coalfield. Spores of the genus range up into the Westphalian D coal seam n3.
