On the cortex of a block of flint, of an oval morphology, is an engraving with an elaborate phytomorphic motif. From one line, rectilinear or slightly sinuous, numerous short, oblique lines branch out, more or less parallel, which become gradually shorter towards the upper end.
On one side eight juxtaposed and iso-oriented modules are visible. The opposite face is used for six marks arranged in a radial pattern.
The iconography and the design of the engraving recall the phytomorphic painted figure of Riparo Villabruna A.
