Passage
Sedimentary layers form when changes in the environment cause changes in the top soil of the area. As pressure is applied from the additional layers, fossils are formed.
Figure 1 shows the different depths and pressure conditions under which different Fauna (categories of fossils) are formed.
A fossil’s formation stage (a measure of the age of the fossil) is classified on a scale of early (first recovered) to late (deeply buried). Table 1 lists the grades of Fauna A–I from Figure 1. Figure 2 shows characteristic compounds that may be found in fossils of a given stage.


Q. According to Figure 2, the presence of which of the following compounds in a fossil is the least helpful when determining the fossil’s stage?
  • a)
    Hydrogen
  • b)
    Trilotite
  • c)
    Amber
  • d)
    Eurypterid
Correct answer is option 'A'. Can you explain this answer?

The best answer is A. Figure 2 shows the characteristic compounds that may be found in fossils at a given stage. Hydrogen appears in fossils at all stages, and therefore, will not be helpful in determining a fossil’s stage; this information best supports answer choice A.
