FIGURE 58. Distribution of species in localities outside of the study area. The thickness of bars corresponds to the number of localities where the species was found. Black bars correspond to species that occurred before and after the base of the Valanginian, light blue bars to species that occurred only in the Jurassic and Berriasian, and light green bars to species that are only known from the Valanginian on. The vertical dark green bar marks the age of the investigated coral fauna.

FIGURE 60. Correlation of the palaeo-provinces where species of the studied fauna occur. Only provinces with more than two species were included, and only the time period Oxfordian to Aptian was considered. The Correlation Ratio coefficient was applied, the graph is logarithmic. Abbreviations: Ju, Jurassic; Ox, Oxfordian; Ki, Kimmeridgian; Ti, Tithonian; C, Cretaceous; Be, Berriasian; Va, Valanginian; Ha, Hauterivian; Ba, Barremian; Ap, Aptian; Al, Albian. The number one indicate lower, the number two upper, in the Ju2-3 indicates Middle to Upper Jurassic. The numbers in brackets are the numbers of joint species. The study area is marked in bold letters.

FIGURE 61. Critical stratigraphic ranges of the coral genera in the study area. Ranges after Löser (2016), but improved by newer data. Black lines indicate genera that occurred before and after the Early Valanginian, light blue lines genera that have their last occurrence in the outcrop area, light green lines genera that have the first occurrence in the outcrop area. The vertical green area shows the age of the studied fauna.

FIGURE 62. Critical stratigraphic ranges of coral families with a distribution in the time period Oxfordian to Aptian. Ranges after Löser (2016), but improved by newer data. The thickness of bars corresponds to the number of genera of the families. When a range is given for a superfamily, it collects only one family. The vertical green area shows the age of the studied fauna.
