Fossil record has not been given. It has been attached. Options for the question are also not given. They are listed as follows:

1. Birds and flowering plants inhabited this area at about the same time period.

2. Animals with shells and fish appeared on Earth before land plants.

3. Flowering plants were critical to the appearance of insects.

4. Vascular plants appeared during the same period as mammals.

5. Humans were the last to appear at this site.

1. Birds and flowering plants inhabited this area at about the same time period.

2. Animals with shells and fish appeared on Earth before land plants.

5. Humans were the last to appear at this site.

Explanation:

According to the given fossil record:

Birds appeared in jurassic-cretaceous period while flowering plants appeared in cretaceous period. Since cretaceous period overlaps for both we can say that birds and flowering plants inhabited this area at the same time. Animals with shells are present right from the cambrian period whereas even the earliest land plants (club mosses) appeared as late as devonian era. So animals with shells and fish appeared on Earth before land plants.Humans appeared very late right before the beginning of quaternary period. By then all the other animals and plants had appeared at this site. So, humans were the last to appear at this site.
