Geologists and paleontologists are highly self-critical, and they have worried for decades about these issues. D., is a vertebrate paleontologist with particular interests in dinosaur origins and fossil history.Repeated, and tough, regimes of testing have confirmed the broad accuracy of the fossils and their dating, so we can read the history of life from the rocks with confidence.

Currently, he is studying certain basal dinosaurs from the Late Triassic and the quality of different segments of the fossil record.He holds the Chair in Vertebrate Paleontology at the University of Bristol, UK, in addition to chairing the Masters program in paleobiology at the university.

Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.

Today, innovative techniques provide further confirmation and understanding of the history of life.

Biologists actually have at their disposal several independent ways of looking at the history of life - not only from the order of fossils in the rocks, but also through phylogenetic trees. Relative dating is done by observing fossils, as described above, and recording which fossil is younger, which is older.

Age estimates can be cross-tested by using different isotope pairs.

Results from different techniques, often measured in rival labs, continually confirm each other.

These skeptics do not provide scientific evidence for their views.

Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.

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.
