Answer:
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.
