Final answer:
Fossils of the same species found together indicate C. their social behavior and group dynamics. The fossil record helps understand the evolution of species, but individual life spans are determined through other specific methods.
Step-by-step explanation:
When fossils of many individuals of the same species are found together, it most likely tells us about their social behavior and group dynamics. Finding these fossils in one location could suggest that the species lived in herds or groups, which is relevant to understanding their behavior and how they interacted with each other. Mass migration events might be implied if the location is along a known migration route, while the geological history is derived from studying rock formations and not solely the presence of fossils.
The fossil record is vital as it shows the evolution of form and adaptive strategies over millions of years, yet the individual life spans of the organisms are determined more accurately through the study of growth rings in individual bones or other specific methods rather than group fossil finds.
