Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
The study and record of fossils as done by planetologists has evolved greatly... from using hands to dig up bones and other fossil types to the use of machinery and from guessing possible ages of those fossils to the use of technology for more accurate data and results.
