In 2014, accidentally ploughed human bones were discovered in the field in the village Rzeczyca Sucha, Sandomierz district, and a year later rescue and trial archaeological excavations were carried out. In the course of research, two poorly preserved human burials were uncovered. One of them contained grave goods and those were two pendants made of shells. It was possible to establish C14 dating on the basis of one of the skeletons. The results of the research indicate the end of the Neolithic period.
