According to the principle of faunal succession, what can you accurately conclude from the image shown?
image of rock layers. the top layer is off white and separated into pieces by vertical lines. the next layer is gray and made of multiple layers indicated by horizontal lines. the next layer is yellow brown, double the width of the first layer and divided by vertical lines. the next layer is gray and made of multiple layers indicated by horizontal lines. this layer is labeled a. the next layer is off white and contains yellow brown shell shaped pieces. the next layer is green. the next layer is off white, quite narrow, separated into two narrow layers and separated by horizontal lines. the next layer is gray and made of multiple layers separated by horizontal lines. this layer is labeled b. the next layer is orange. the next layer is gray and made of multiple layers separated by horizontal lines. the next layer is off white, quite narrow, separated into two narrow layers and separated by horizontal lines. the next layer is yellow brown and separated by horizontal lines. the next layer is orange. the next layer is gray and made of multiple layers separated by horizontal lines. this layer is labeled c. the next layer is green and contains 2 trilobite shaped pieces. the next layer is gray and divided into multiple layers with horizontal lines. this layer is labeled d. the next layer is off white and divided by vertical lines. the next layer is green. the next layer is yellow brown, narrow and divided by vertical lines. the bottom layer is off white, narrow and divided by vertical lines.

the fossils at the base of rock layer a are embedded in igneous rock.

the fossils at the base of rock layer c are millions of years old.

the fossils at the base of rock layer c are older than those at the base of rock layer a.

the fossils at the base of rock layer a represent an organism that is now extinct.
