Ancient stone sculpture from Papua New Guinea
The Ambum stone is an ancient stone sculpture thought to have been carved c. 1500 B.C.E. Other similar stones excavated depict humans, birds, or other animals.[2] Scientists are unsure exactly which animal this sculpture is meant to represent, but some believe it may represent a now extinct marsupial. Speculation also surrounds the objects intended purpose, some believe that it may have acted as a pestle.
