Julien Riel-Salvatore mentions today in his blog that another instance of Neanderthal hafting has been discovered, this time in Romania (Râşnov Cave), dated to 33.3-28.9 Ka. BP (uncalibrated) and with Mousterian technology (generally associated with Neanderthals).
A previous case was known to exist in Palestine (Umm el Tlel, c. 40-70 Ka BP). Findings of birch pitch tar, also used for hafting, are even older: 125 Ka in Germany and maybe even older in Italy, evidencing the use of different technical solutions for the same problem.
I refer to A Very Remote Period Indeed for the papers and further details.
