When a large number of species go extinct over a relatively short time period

• geologic time scale

• fossil record

• mass extinction

• evolution

The history of life on Earth as documented by the fossils collected so far.

• geologic time scale

• law of superposition

• fossil record

• mass extinction

Scientist find dinosaur fossils in the bottom of a cliff and mammals fossils in the middle layer, what can be inferred?

• dinosaurs ate plants
• dinosaurs were eaten by the mammals
• they lived at the same time
• dinosaurs lived before the mammals

This makes an organism more suited to its enviornment

• species
• lifespan
• adaptation
• mutation
