by the geographic locations where they are found
D
by similarities and differences in their body structures
Explanation: 

Detailed explanation-1: -Fossils can be compared with one another and to living organisms according to their similarities and differences. By the end of grade 8. Fossils are mineral replacements, preserved remains, or traces of organisms that lived in the past.
