Famennian Corals from the southern Holy Cross Mountains

Maria Rozkowska

Abstract

The study of the Famennian corals is one part of the complex investigation of the Famennian of the southern Holy Cross Mountains.

Rich and diverse coral faunas have been collected from Famennian deposits at the localities. The stratigraphic range as established by conodonts is given.

1) Kadzielnia: crepida Zone, rhomboidea Zone and quadrantinodosa Zone.

2) Lagow: Upper rhomboidea Zone and quadrantinodosa Zone.

3) Zareby: Conodonts lacking.

4) Galezice: Quadrantinodosa Zone, velifera Zone, styriaca Zone (?), and costatus zone.

5) Jablonna: Triangularis Zone - costatus Zone (very few tetracorals).

6) Kowala: Costatus Zone.

The rugose coral fauna of the Famennian is nearly unknown. Fifty rugose coral species and subspecies are described with 9 new genera, 29 new species and 5 new subspecies.

Genera have been distinguished by detailed consideration of internal structure and external morphology, but essentially by ontogenetic study. Special attention has been paid to variation.

The significance of the Famennian Rugosa as indicators of time and facies has been examined, involving the investigation of the whole faunal assemblage and its state of preservation.
