Definition of relative dating of fossils
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.
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.
Also includes info on how fossils are formed, the “cleaning, preparing, & repairing” of fossils, and other useful resources.
Instead, other methods are used to work out a fossil’s age.
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.
Knowing when a dinosaur or other animal lived is important because it helps us place them on the evolutionary family tree.
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.
Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods.
Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.
