Tree rings are annual growth rings and their thickness indicates how growing conditions were for that year. Index fossils in their type and frequency are indicative of the environment that those organisms grew in and how prolific life was then in that environment.

When he took an arrow through the chest and another in the leg, he pressed on – the wounds only spurred him on to fight harder.
