Grociki krzemienne z młodszego neolitu i początków epoki brązu z terenu Dolnego Nadodrza

The paper presents a multifaceted analysis of flint arrowheads. It was based on an assemblage of 121 artefacts from 57 sites located in the lower Odra River area. The chronological scope of the study includes the period from the younger Neolithic to the early Bronze Age. During the study, the flint raw material of which the arrowheads were made, the morphology of this type of artefact and the production technology of flint arrowheads were analysed amongst others. The article is also accompanied by a catalogue with plates showing the majority of the collected arrowheads. In the assemblage in question, the most numerous flint arrowheads were stray finds. In addition, material originating from settlements and cemeteries only tested or not excavated at all limited the possibilities of wider analyses comparing the discussed type of sources with cultural units. In the case of raw material, based on these general observations, it can be concluded that for the production of flint arrowheads more fissile raw material, probably of local origins was used. Based on the undertaken analyses, it can be stated that heart-shaped forms dominated as in other regions of Central Europe, where they were the most popular form in assemblages of late Neolithic and early Bronze Age cultures. In terms of the production technology of the flint artefacts in question, a notable domination of arrowheads made of flakes was identified. In addition, the majority of them bear parallel and transversal retouch as well as invasive retouch, whose execution is linked with the high skills of flint production. In the case of additional techniques used in production, however, an occurrence of jagged edges can be observed.
