Answer 2

Answer:

The fossils of the organisms from the "Phanerozoic Eon" are much more likely to be found than "fossils of organisms" from any other eon because more organisms present during the Phanerozoic Eon had hard body parts.

Explanation:

• The Phanerozoic Eon marks the period that we are currently living in.

• Thus, the fossils of organisms from this period are most likely to be found than the "fossils of organisms" form any other eon.

• The beginning of this Eon was marked around '541' million years ago. Because the animals in the early Phanerozoic Eon had hard body parts, the disintegration of their body parts took millions of years.

• This allowed the fossils of these animals to stay intact for a very long span of time.
