Explanation:
It is clear to see that the utilization of full body plates drastically increased and the usage of half body plates dramatically decreased. This is likely showing that these fish were heavily targeted, and therefore, needed to use better defensive mechanisms; hence the usage of full body plates compared to two-thirds or half. This is all showing these fish were likely prey for bigger fish, or perhaps non-marine predators as well.
