The Lower Paleolithic in Transylvania, because data are scarce, is largely a mystery. If the discovery of an Acheulean lithic item at Căpuşu Mic (Cluj County) and of several Pre-Mousterian lithic items at Tălmaciu (Sibiu County) are a certain fact, their precise stratigraphic position remains to be established. The same cannot be said about the discoveries in the Ciucului Basin at Sândominic (Harghita County) where several tools, and a rich fauna, have been encountered in certified stratigraphic positions, belonging to the geo-chronological interval covering the late Mindel to the early Riss.
