After disappearance of the Foliomena Fauna, the glacioeustatic sea level drop brought the shallower fauna basinwards. The bryozoan-brachiopod-pelmatozoan fauna appeared in the highly fossiliferous calcareous claystone (?pern\u00EDk? bed). The ?Pernik? bed yields transported bioclasts and many subautochthonnous deep-water elements, namely small strophomenoids and some trilobites. This fauna was followed upward (at the summit of the Kr\u00E1l\u016Fv Dv\u016Fr) by the Hirnantia Fauna Formation due by drastic cooling at the beginning of the Hirnantian."@en . .
