The of a skeleton can be determined by observing the shape of the pelvis and sacrum, the size of the cranium, and the protrusion of the brow bone and mastoid process.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !

i'd say that the moon rock is about 2.2 billion years old.
