Summary Introduction
Introduction: Fossils are the traces and leftovers of organisms that lived during the ancient times. The majority of the fossils consist of teeth, seeds, shells, mineralized bones, and spores of the ancient organism. Also, the impression of the foot prints, burrows, nests, eggshells, trails, or feces can collectively contribute to the evidence of life during the ancient times.

Scientists find an artifact next to an index fossil. What can they conclude about the unknown age of the artifact?
a
The artifact is older than the index fossil.
b
The artifact is younger than the index fossil.
c
The artifact is approximately the same age as the index fossil.
d
The artifact's age is not related to that of the index fossil.
Which is true concerning how fossils are used as evidence?
A.
Fossils cannot be compared to one another but can be compared to living organisms.
B.
Fossils can be compared to one another but not to living organisms.
C.
Fossils cannot be compared to one another or to living organisms.
D.
Fossils can be compared to one another and to living organisms.
