Orthid brachiopods from the Upper Visean (Carboniferous) of the Świętokrzyskie Mts., Poland
Halina Żakowa
Enteletid (four species) and rhipidomellid (one species) brachiopoda from the Gałęzice region. SW Świętokrzyskie Mts., have been described. Dominating genus Schizophoria is represented by S. (Schizophoria) resupinata, S. (S.) keyserlingiana. S. (Paraschizophoria) woodi, S. (Pat.) sp. A, S. (Pocockia) linguata, S. (P.) cf. gibbera. Six known morphological "varieties" or "forms" of S. (S.) resupinata have been described. They probably come from diverse environments. Most specimens collected belong to S. (S.) resupinata (Martin) forma typica and represent all stages of its ontogeny. The brachiopods have been collected from organodetritic limestones and calcareous-clayey deposits of the Goniatites crenistria and G. striatus zones. It is suggested that only S. (S.) resupinata f. gigantea may be stratigraphically characteristic of the Upper Visean of Europe.
Key words: brachiopods, taxonomy, stratigraphy, Upper Visean, Swigtokrzyskie Mts., Poland.
