I just want to mention that I have discovered today a couple of probably important elements I was unaware of earlier in regard to the Middle-Upper Paleolithic transition in Europe.
The Lincombian culture
The first one is dealt with in detail by Millán Mozota at his blog (in Spanish but all reference papers are in English) and is the Lincombian-Ranisian-Jerzmanowician (LRJ) culture. This techno-culture shares the general evolution towards characteristic Upper Paleolithic blade technology but is however quite different from others we know in the typological aspect, styling a distinctive double-faced retouch.
Extension and typical LRJ point (Semal 2009)
This culture is most probably the work of Homo neanderthalensis, as it was found along with Neanderthal remains in the cave of Spy in Belgium (however in flagrant case of bad archaeology where the archaeological context was totally destroyed and not documented). These remains have been recently carbon-dated and display a date of c. 36,000 years BP (very roughly c. 45,000 years ago after calibration), suggesting that both are related.
Wooden spear from Slovenia
The other item I stumbled upon today is the existence of a unique spear point made of yew wood. This point was discovered in 2009 at the Ljubljana Marshes near Sinja Gorica in Slovenia and is said to have Szeletian affinities (source: Ljubljana Municipality).
You tell me if this is not fascinating. There has been for long speculation on the existence of such wooden tools and weapons (for instance in SE Asia where bamboo might have been a material of choice) but so far no direct evidence.
The spear is believed to date to 38-45,000 years ago, though I am not aware that it has been dated by any method.
