Cast of the lower jaw AL 400 1a, found between 1974 and 1977 at Hadar, Africa, by Don Johanson. It is dated to about 3 million years old. It shows characteristic features such as a relatively long and narrow jaw, moderately-sized back molar teeth with human-like ‘Y-5’ pattern and relatively wide incisors.
