Radiometric dating debate
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.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.Older dates may change by a few million years up and down, but younger dates are stable.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.He has written some 30 books on dinosaurs and paleobiology, ranging from professional tomes to popular kids’ books.

Paleontologists now apply sophisticated mathematical techniques to assess the relative quality of particular fossil successions, as well as the entire fossil record.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.Also includes info on how fossils are formed, the “cleaning, preparing, & repairing” of fossils, and other useful resources.Most scientists today believe that life has existed on the earth for billions of years.
