AUSTRALIA -- Scientists in Australia opened what they thought was an empty 2,500-year-old coffin and found a mummy.
The University of Sydney acquired the coffin 150 years ago.
Before the discovery, records classified the coffin as empty and it was left untouched.
Initial studies show the remains found inside are of a single human, an adult probably around the age of 30.
The discovery offers scientists a rare opportunity to test the corpse that could help unlock mysteries around ancient Egypt.
