A female figurine which has 'no practical use and is portable' and has the common elements of a Venus figurine (a strong accent or exaggeration of female sex linked traits, and the lack of complete lower limbs) may be considered to be a Venus figurine, even if archaeological evidence suggests it was produced after the main Palaeolithic period. Some figurines matching this definition originate from the Neolithic era and into the Bronze Age. The period and location in which a figurine was produced helps guide archaeologists to reach conclusions as to whether the art piece found can be defined as a Venus figurine or not. For example, ceramic figurines from the late ceramic Neolithic may be accepted as Venus figurines, while stone figurines from later periods are not. This is a matter of ongoing debate given the strong similarity between many figurines from the Palaeolithic, Neolithic and beyond. A reworked endocast of a brachiopod from around 6000 BCE in Norway has been identified as a late Venus figurine.
