                       What can fossils tell us about ancient            What was Earth’s climate like when
                                 environments?                                    dinosaurs lived?





































                Fossils also show that Earth’s                                     SUMMARY
                climate has warmed and
                cooled many times in the past.                       Fossils: What is in the Ancient Environment?


                Plant fossils are especially                         Fossils can form in many different ways.
                good indicators of
                climate change.                                      Fossils help scientists learn about Earth’s
                                                                    ancient organisms and past environments.


                Fossils of some plants reveal that 100 million years
                ago, Earth was very warm and covered by tropical
                forests and swamps.

                Fossils of some organisms, like ferns and woolly
                mammoths, help scientists learn about ancient
                organisms and past environments.
