Age and floristic relationships of the Late Pennsylvanian vegetation of SW Croatia

Upper Pennsylvanian deposits in the Velebit Mts and Lika region of Croatia are mainly marine, but also include relative thin terrestrial intercalations. The latter yield diverse fossil floras dominated by medullosaleans (especially Alethopteris ) and sphenophytes, and represent the remains of the lowland vegetation that gr ew on the southern side of the Variscan Mountains. Biostratigraphical ly they belong to the S. angustifolium Zone of the Stephanian B Substage (late Kasimovian or earliest Gzhelian) age. They compare most closely with similar aged floras found in northern Spain and the Carnic Alps. In contrast, similar aged floras from intra-montane sequences further north and west in Europe often tend to be dominated by marattialean ferns and cordaitaleans. These differences are probably the result of the higher elevation and better drainage of the intra-montane basins.
