In the Stephanian and the Autunian the rate of denudation increased, which is indicated by the unconformity surface at the contact with the Westphalian, poorly sorted deposits and distinctly lower accumulation potential of the area (relatively low thickness and numerous erosional surfaces in the deposits of the Svatonovice Mb.).
Plant remains are of particular abundance in the lacustrine blackshales of the lowermost part of the Autunian Group and vanish progressively upwards because of the low potential of preservation in the red playa/floodplain pelites of the Saxonian Group.
These sediments (formerly named "Grey Autunian") were deposited under a warm and humid climate indicated by laminated lake sediments which yielded a rich and well-known flora dominated by conifers but where callipterids show a remarkable diversity (Grand'Eury, 1877; Zeiller, 1898; Florin, 1938-1945; Doubinger, 1956).
In the Lower Autunian Group of the Lodeve basin western part, Debriette and Gand (1990) described Trachomatichnus Miller, 1880, a morphotype similar to those of the trackways coming from the Salagou Formation.
The materials which contain this flora are considered Autunian. In the Autun basin it is not possible to observe the relationships with the underlying Carboniferous or with the upper levels.

The Iberian Massif did not exist as an entity before Stephanian C (= early Autunian) times *.
