If the fossils, or the dating of the fossils, could be shown to be inaccurate, all such information would have to be rejected as unsafe.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.
Results from different techniques, often measured in rival labs, continually confirm each other.
Every few years, new geologic time scales are published, providing the latest dates for major time lines.
These demonstrate that, of course, we do not know everything (and clearly never will), but we know enough.
Today, innovative techniques provide further confirmation and understanding of the history of life.
Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.
