Russia uncovers 40,000 year-old wolf head, preserved in ice
About 40,000 years ago, a wolf died in what we know as Siberia. Now its severed head has been found, and because of the freezing conditions, it is so well preserved that its fur, teeth, brain and facial tissue are largely intact. A Yakutia resident, Pavel Yefimov, found the head last summer on the banks of the Tirekhtyakh river, close to the Arctic Circle in the region of Yakutia, local media outlet the Siberian Times reported.
Marijuana chemical residue has been found in incense burners apparently used during funerary rites at a mountainous site in western China in about 500 BC, providing what may be the oldest evidence of smoking cannabis for its mind-altering properties. The evidence was found on 10 wooden braziers containing stones with burn marks that were discovered in eight tombs at the Jirzankal Cemetery site in the Pamir Mountains in China's Xinjiang region, scientists said on Wednesday. The tombs also bore human skeletons and artifacts including a type of angular harp used in ancient funerals and sacrificial ceremonies.
