Hanna Górka


Described holothurian sclerites represent two families: Synaptitidae and Caclamnidae. Basing on its mass occurrence Croneisites polonicus Górka et Łuszczewska has been considered an index taxon for the Miocene. Holoturian sclerites are accompanied by foraminifers belonging to the following genera: Elphidium, Bulimina, Neobulimina and Triloculina. Their presence confirms a conclusion that the sediments were deposited in a warm and shallow-marine environment.
