Piatra Tomii is a late Jurassic limestone outcrop forming a small hill near Răcătau village, Alba county, Romania.
The large size of the settlement compared to its relative isolation high in the Apuseni Mountains tends to support this theory.
[1] This is based on initial comparisons of Neolithic chipped stone artifacts to the geological material at Piatra Tomii.
This theory has not yet been confirmed by the archaeological record for the middle Neolithic period, but during test pitting in 2009, Petrești type pottery was found at the site, indicating that the site was in use long prior to the arrival of the Coțofeni population (and possibly abandoned until the late Coțofeni people arrived).
Since only a small percentage of this site has been excavated, it is also possible that remains of Vinča culture simply have not yet been found at Piatra Tomii.
