ARTYKUŁY NAUKOWE O rzekomym wystąpieniu makroskamieniałości Helcionelloida i meduz w kambrze Gór Świętokrzyskich

Abstract

On the alleged occurrence of Helcionelloida macrofossil and medusae from the Cambrian of the Holy Cross Mountains.A b s t r a c t. Amongst the materials collected from the Cambrian outcrops in the Holy Cross Mountains by priest professor Włodzimierz Sedlak, there is a holotype and only specimen of Helcionella polonica, as well asa rock fragment with casts of medusoids on its surface. We decided to revise these materials for their importance to discussions on the early molluscs’ size and the medusae fossil record; as well as for the criticalnature of previously published revisions of taxa erected by Sedlak.
