Conchostraca (clam shrimps) from the lowermost Buntsandstein at Zachełmie, Holy Cross Mts, central Poland.
S u m m a r y. Contemporary Conchostraca (clam shrimps) live in temporary and permanent freshwater ponds and pools. They have wide geographic distribution. Their fossils are abundant in the Buntsandstein and very important markers for chronostratigraphic correlation between marine and continental sections. The conchostracan assemblage found in the lowermost Buntsandstein at Zachełmie quarry: Falsisca postera, Falsisca eotriassica, Palaeolimnadia cf. cishycranica, Euestheria ex gr. gutta, Euestheria gutta oertlii indicates
the uppermost Permian age of at least the most of Jaworznia Formation (A1 petrographical complex), cropping out at the Zachełmie quarry in the Holy Cross Mountains, Poland.
