Part of the collection of the Laboratory of Primatology and Paleontology at the University of Antananarivo, the jawbone that the team used in its study had originally been discovered at Beloha Anavoha in southern Madagascar. Carbon-14 dating, a commonly used method for determining the age of archeological artifacts of a biological origin, revealed that the M. edwardsi jawbone was about 1,475 years old.
