It is oxidised quickly and absorbed in great quantities by all living organisms - animal and plant, land and ocean dwelling alike.

Radiocarbon dating may only be used on organic materials.

Typically (6): The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left.
