"Manfred Bietak pointed out other dangers in dendrochronological dating. It is ‘methodologically wrong to compare different varieties of wood originating from different regions…The ecosystem could be…different. Also different kinds of trees react to climate in different ways. The juniper is from central Anatolia…Far away from one housing cedar…likely to be from a region near the seashore…[thus] we are forced to use the artefacts from the ship as a way of dating.’"
