Authorities have positively identified bones found on a mountain as those of Steve Fossett. Two large bones found a half-mile from where the adventurer's plane crashed in California's Sierra Nevada mountains.

Madera County Sheriff John Anderson said DNA tests conducted positively identified the bones as the remains of the millionaire aviator who disappeared last year. Fossett's tennis shoes and driver's license were also found at the site, both with animal bite marks on them.

Anderson says Fossett would have died on impact and that it's not unusual for animals to drag away remains.

Fossett vanished in September 2007 after taking off from a Nevada ranch in a stunt plane.
