Such rocks, usually shale, sandstone or limestone, were produced on sea bottoms where sand, mud or thick beds of shells have been compressed into solid stone must be met by nature before an animal or plant can become a fossil.First, the organism must be rapidly buried within sediments which are not soon disturbed.For example, Christian time counts the birth of Christ as the beginning, AD 1 (Anno Domini); everything that occurred before Christ is counted backwards from AD as BC (Before Christ).The Greeks consider the first Olympic Games as the beginning or 776 BC.

When it comes to dating archaeological samples, several timescale problems arise.
