Discoidal core

The core is made of very good quality flint from layered or nodular raw materials (lying in natural deposits in layers or individual nodular stones). Judging by the negatives of the chips on the surface of the cleavage front, it was intensively used. Striking platforms were located on several sides of the object; they were formed by large chips, which created the angle necessary for work between the striking platform and the plane of the cleavage front. When the platform or the cleavage front was severely damaged, the platforms were reshaped to make it easier to separate the next chips with a blow.
The main products of the splitting of such cores were flakes, less often - plates, usually not very regular, for example, with curved, non-parallel edges and uneven thickness. The back side of the core, the so-called counter-front, was almost not processed; traces of the natural limestone crust that covered the original nodule, unprocessed by human hands, remained on it.
It has a functional purpose: a blank for obtaining the next chipped blanks for future flint tools.
It is a typical item of the Middle Paleolithic era in Europe.
