This Homo erectus skull was featured on the cover of American Scientist in 1996. It was discovered by S. Sartono in 1969, the most complete of more than 80 specimens from the Indonesian island of Java. It was named Sangiran 17 after its geographic locality. Note the long cranium, low forehead, and massive structure typical of Homo erectus in East Asia. The estimated age of this skull is more than one million years old, providing evidence for the theory that early hominids first migrated out of Africa for Asia much earlier than previously thought.
