The fossil remains of a terrestrial organism are found in canada. these fossils appear to be similar to fossils found in the midwestern united states, and also to fossils found in northern europe. what would be the best first step in a scientific procedure for determining if one of these organisms could be an ancestor of the others?

Determination of age if the fossils may help in determining the ancestry of these fossils, and their linked evolution. Radiometric dating is used to measure the radioactive decay of the sample and can be used for estimating the fossils of more than 50 million of years. Stratigraphy can also be used for studying the layers of the fossils. All the techniques covered in the study of fossils, fall under the category paleontology.
