Other than these testimonies of such a remote human presence in Finale, referable to Homo heidelbergensis, the Fairy cave is particularly important for northern Italian prehistory with the fact that, from the layers datable to 70 thousand years ago, 16 fragments  of human bones were discovered, also in an incomplete state, that belonged to the Neanderthal man. Such human remains were partially recuperated by G.B. Amerano at the end of the 19^th century and partially came to light during more recent excavations include remains of adults and children.

In the Fairy cave the Neanderthals left evidence of their existence also through hearths and numerous chipped stone tools. To build their tools they used various kinds of rocks: principally quartzite and limestone. This not only documents a certain opportunism but also demonstrates that they had reached an advanced technique, so skilled as to be able to make efficient tools even from inadequate types of stone.

The cave also preserved numerous remains of cave bears (Ursus spelaeus) that lived around between 200 thousand and 20 thousand years ago. Cave bears were spread out in the majority of European territory, apart from the most southern areas. They preferred environments with medium forestation or with scarce vegetation with a mild climate to almost a cold climate. In the winter months the bears would hibernate in caves: this kind of behaviour has made possible the finding of a large quantity of bones of bears that died within the cave where they were staying, just like in the Fairy cave. A complete bear skeleton in now exhibited in the halls of the Archaeological Museum of Finale along with the other findings of the cave.
