Abstract

Pathological features on the conulariids exoskeletons has not been studied on the Bohemian material yet. Some of them can help to reconstruct various events in the life of conulariids. The contribution brings the basic classification of pathological features and their description. The pathologies represent predominantly sublethal damages of the exoskeleton which were healed by living organism. The interpretation of their origin gets closer to some details of the mode of exoskeleton growth and the risk of predator attack.
