Abstract
Investigations on Hutk section prove the age of Middle Frasnian to Early Famennian for this section. Three genera and eighteen species have been obtained. Index species such as P. zinaidae and I. vitabilis show the age of Middle to Late Frasnian (hassi – linguiformis Zone) for the lower part of the section.   Some of the Famennian index species such as P. semicostatus, I. cornutus, I. iowaensis iowaensis and Pel. inclinatus reveal the age of Early Famennian (triangularis – Late crepida Zone).
The new age ranges for some species have been determined in this paper. The earliest presence of I. iowaensis seems to be in Middle Frasnian and the range of P. alatus extends to Early Famennian. The oldest specimens of P. communis can be observed at the base of Hutk section by the age of Middle Frasnian.
