Question
Chapter 13, Problem 6WIO
Summary Introduction
To determine:
The ages of the fossils found in eastern South America and western Africa without using the absolute or relative dating techniques
Concept Introduction:
The fossils are the old conserved remains found in the rocks the oldest rocks contain the fossil records of the earliest organisms, while the fossil remains of newly evolved organisms are complex as compared to that of simple organisms. The evolution can be studied with the help of fossil records.
