However, it wasn't until the mid 20th century that scientists could abandon this pathetic, inaccurate process and move into a more acceptable precise and detailed procedure. The old way was done by comparing one fossil to other fossils found in the same layer of the earth's ground and studying the physical characteristics of the fossil. Scientists took guesses and made assumptions of the age of a fossil and what time period in belonged to. With the discovery of chronometric dating, finally, a whole new world of answers and possibilities came into view and it opened doors to more precise and sensible answers to many questions that scientists had been asking for years.
