Article Abstract:

Several rock engravings and stone tools have been discovered in a remote site in the Northern Territory of Australia called Jinmium. These artifacts, which have been dated to about 75,000 and 176,000 years, could weaken popular convictions asserting the origin of art during the Upper Palaeolithic period in Europe and the absence of human occupation in Australia prior to 60,000 B.C. However, the dating techniques used in the artifacts has been called into question and researchers are considering the use of a new technique called OSL to verify the age of the findings.

Flight into pre-history

Article Abstract:

Analysis of a replica of an ivory boomerang of the prehistoric age suggests that it is a straight-flying tool, weighing 800 grams with a broad handle and camp and can be used with the right or left hand without affecting flight qualities. The replica travels up to 66 m and its flight is more affected by an opposing wind than by an imposing wind. The flight path remains uniform in various climates.
