Following the practice of previous years, also this summer sediments from archaeologically excavated objects were floated at archaeological base Mikulčice-Trapíkov. This season were floated mainly samples from this year’s excavations at Kostelisko (burial site), but also from last intensively settled part of acropolis – Dolní Valy. Floated archaeobotanical material will be then subjected to microscopic analysis that help to clarify the nature of the settlements in the investigated areas.
