Ancient bone tools found in caves in Western Australia have been confirmed to be among some of the oldest ever found.
The bones have been dated to be more than 35,000 years old; the discovery confirms that bone tools have been used longer than previously thought.
The tools are made primarily from kangaroo bones, and were believed to have been used for a multitude of tasks including, splitting resin and as spear points for hunting. Such archaeological finds are rare in Australia due to harsh climate conditions causing bones to decay quickly.
