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.
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.
The fossil record is fundamental to an understanding of evolution.
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.
He has written some 30 books on dinosaurs and paleobiology, ranging from professional tomes to popular kids’ books.

online directory of dinosaur exhibits fro around the world. t=sub_pages&cat=8 Many natural history museums and universities worldwide offer public participation programs in dinosaur events, such as fossil hunting or fossil cataloguing. The list is too long to mention here, so a couple of examples are provided to get you going on your search for programs in your area: Explore U. fossil collecting locations that are detailed on this site.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. Educators have permission to reprint articles for classroom use; other users, please contact [email protected] reprint permission. 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.All these labors have not led to a single unexpected finding such as a human fossil from the time of the dinosaurs, or a Jurassic dinosaur in the same rocks as Silurian trilobites.Paleontologists now apply sophisticated mathematical techniques to assess the relative quality of particular fossil successions, as well as the entire fossil record.Libby received the Nobel Prize in Chemistry for his work in 1960.
