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.

Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils.
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.
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.
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.
