The characteristics of fossils that are most useful in correlating sedimentary rock layers are:
Wide geographic distribution but limited to a particular formation.
Explanation:
the reason behind this answer is because the correlation of sedimentary rock layers requires a geographic distribution large enough to preserve all the fossil elements. However, it requires to be only a zone delimited to the body of fossilization because otherwise, it could contain elements from another fossil.
This question had choices. They are the following: (1) Limited geographic distribution but found in many rock formations (2) Limited geographic distribution and limited to a particular rock formation (3) Wide geographic distribution but limited to a particular rock formation (4) Wide geographic distribution and found in many rock formations
My answer is: 3) Wide geographic distribution but limited to a particular rock formation.
