Potassium isotope dating
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.
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.
He has written some 30 books on dinosaurs and paleobiology, ranging from professional tomes to popular kids’ books. Learn the facts in Evolution 101, browse the resource library, read about evolution in the news, or discover a wealth of materials to help educate others about evolution and related concepts—it’s all right here!

Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
However, to read any clock accurately we must know where the clock was set at the beginning.
Fossils can also show us how major crises, such as mass extinctions, happened, and how life recovered after them.
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.
The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them: Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution.
Also includes info on how fossils are formed, the “cleaning, preparing, & repairing” of fossils, and other useful resources.
Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.
