Dating fossil record carter county tn dating

Perhaps the record of biodiversity in the fossil record is more accurate than previously feared.

Professor Michael Benton from the University of Bristol, another co-author of the study, said: "Palaeontologists are right to be cautious about the quality of the fossil record, but perhaps some have been too cautious.

It is beyond dispute among geologists that on every continent we find fossils of sea creatures in rock layers which today are high above sea level.

All of these measures have been used as yardsticks against which the quality of the fossil record can be assessed -- but the new study casts doubt on their usefulness.

Dr Dunhill said: "We suspected that the similar patterns displayed by the rock and fossil records were due to external factors rather than the number of fossils being simply dictated by the amount of accessible rock. Factors such as counts of geological formations and collections cannot be used to correct biodiversity in the fossil record." The study benefits from the application of advanced mathematical techniques that not only identify whether two data sets correlate, but also whether one drives the other.
