Two methods used for dating fossils

In the past 150 years they have not found any fossils that Darwin would not have expected.New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.For example, it has been known since the 1960s that the famous Cretaceous-Tertiary boundary, the line marking the end of the dinosaurs, was 65 million years old.Repeated recalibrations and retests, using ever more sophisticated techniques and equipment, cannot shift that date. With modern, extremely precise, methods, error bars are often only 1% or so.
