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.
This is very important because archaeologists do not look for fossils. While exploring the woods near my house, I found an arrowhead. 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.
An archaeologist must know the different between an artifact and a fossil.
Early geologists, in the 1700s and 1800s, noticed how fossils seemed to occur in sequences: certain assemblages of fossils were always found below other assemblages. Since 1859, paleontologists, or fossil experts, have searched the world for fossils.
In the past 150 years they have not found any fossils that Darwin would not have expected.
Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.
These skeptics do not provide scientific evidence for their views.
Fossils document the order of appearance of groups and they tell us about some of the amazing plants and animals that died out long ago.
