Correlation of the palaeo-provinces where genera of the studied fauna occur. Only provinces with more than two genera were included, and only the time period Hauterivian to Santonian was considered. The Correlation Ratio coefficient was applied. Abbreviations: Va, Valanginian; Ha, Hauterivian; Ap, Aptian; Al, Albian; Ce, Cenomanian, Tu, Turonian, Co, Coniacian; Sa, Santonian. Number 1. indicates lower, number 2. indicates middle and number 3. indicates upper. The numbers in brackets are the numbers of joint genera. The stratigraphy of the area Pelagonium S margin is uncertain. The study area is marked in bold letters. The dotted line separates Hauterivian to Cenomanian and Turonian to Santonian palaeo-provinces (with one exception).
