evidence\twhat it tells us:

1. growth rings in fossil trees or shells\tgrowth rings tell us the number of years that individuals lived.
2. curled up fossil trilobites\ti
3. the contents of fossil nests
4. fossils of many individuals of the same species together
5. a change in the shape of a feature over time

Explanation:

1. Curled - up fossil trilobites often indicate that they were protecting themselves, perhaps from predators or harsh environmental conditions.
2. The contents of fossil nests can tell us about the diet of the nest - building organisms, what they used to build the nest, and potentially their parental care behaviors.
3. Fossils of many individuals of the same species together can suggest social behaviors like herding, flocking, or communal living.
4. A change in the shape of a feature over time can be evidence of evolution, adaptation to changing environments, or sexual selection.

Answer:

1. What it tells us: Trilobites may have been protecting themselves.
2. What it tells us: Information about diet, nest - building materials, and parental care.
3. What it tells us: Evidence of social behaviors.
4. What it tells us: Evidence of evolution or adaptation.
