Old news. The classic movie "Quest for Fire" vividly depicted this "discovery" years ago.
That movie also depicted four species of hominids interacting, one of which, the large bodied cannibal eating their captured Homo Sapiens, has never been found in the fossil record. The hair-covered species that evicted the Neanderthals from their cave in the beginning of the movie had disappeared at least a half-million years before the time the movie allegedly depicted.
You say it's "classic", I say it's no more than a fantasy movie. Especially the scene where the Neanderthals were confronted by a group of Mastodons that accepted the offering of a handful of grass on the steppe (?) and left them alone.
