The Late Cretaceous deposits in the Lesser Caucasus and in the adjacent regions are characterized by rich diversity of organic world nearly everywhere. In the composition of the organic world a special place is occupied by representatives of a class of Echinoids. On the base of their geographical spread there were constructed maps-schemes for Turonian, Coniacian and Santonian ages. There were also constructed maps-schemes of geographical areals and ways of migration of some species. Most of species of some genera of Echinoids class existing in Turonian, Coniacian and Santonian basins of the Middle-European paleozoogeographical region, widened their geographical areal from the west to the east (Crimea-Caucasus-Kopet-Dag basin).
