Answer:
Footprints are considered to be fossils because they can be preserved for a long time.
Explanation:
- The reason footprints are considered as fossils is that there are certain attributes of fossils that the footprints also have.
- Footprints help determine the size, and apparently the age of the animal.
- They also themselves clarify which animal is the footprint of.
- Moreover, like the evidence of any other physical fossil, footprints also dispense information about the period depending on where and what state it is found in.
