Paleoecological features and stratigraphic significance of the Genus Conoclypus, Echinoidea

Abstract

Five species and a subspecies of the genus Conoclypus from Eocene formations of Croatia and Herzegovina are presented in this paper. Morphology of the genus is analysed. The given paleoecological conclusions are based on morphological data, character of sedimentary rocks containing Conoclypus, associated fauna and mechanical and biotic damages. Stratigraphic significance of this genus is emphasized, because it appeared, flourished, and disappeared in the Eocene period.
