Scientists find the same type of index fossil in two different locations on Earth. What can they conclude from this discovery?
A. The fossils are different ages due to the location.
B. The index fossils are the same geological age.
C. One index fossil is older than the other.
D. There is not enough information to make a conclusion.
B is the most correct answer. When fossils are found in two different locations but are the same type, we know that they're likely the same age. This is also evidence to show that the Earth was composed of land masses that were more closely joined together during these geologic periods.
