Fig. 2 in A new coral with simplified morphology from the oldest known Hettangian (Early Jurassic) reef in southern France
Fig. 2. Stratigraphic distribution of pachythecal corals and related genera inspired from Stolarski and Russo (2001) and modified. As an approximation, a vertical bar indicates a full stage when such corals were identified in the stage. When a single stage lacks such corals between two stages with such corals, the black bar was elongated. By approximation, Štramberk limestone was considered Tithonian. This figure shows only the Triassic– Jurassic range of Pachythecaliines but most of Jurassic genera occur also in the Cretaceous.
