You take a job as a research assistant at one of the richest fossil fields ever to be discovered. On your first day, you discover a new species, Neko borgus, that bears similarities to the modern, domesticated cat. You now begin the task of grouping your many fossils. Can you determine which examples are from the same species by using the biological species concept?

No, because you cannot determine the potential for interbreeding between samples

Explanation:

Richest fossil fields indicates that at some period, there are a large variety of organisms that living on that territory. This could probably caused by high availability of food resources or favorable climate in that area.

When a lot of organism living together, the chance of interbreeding between organism with different genetic composition also increased.  This will make it hard for researchers to determine the species of the fossil.
