A scientist finds the same type of index fossil in layers of rock in both Africa and South America. What does this indicate about the ages of the rocks?
absolute dating
index
It determines the age of the mammoth.
correlation of index fossils
absolute/radiometric dating
Different rock layers can be determined to be the same RELATIVE age if they contain the same index fossils
The rocks are approximately the same age.
isotope
An unstable element that decays at a predictable rate, is a ...
