1. Fossils, adaptation and evolution Where’s the Science in that?

2. 1. Trilobite Trilobites roamed the oceans for over 270 millions years and are known to have first lived about 520 million years ago. What two adaptations helped trilobites stay safe on the ocean floor?

3. 2. Starfish Starfish began to appear during the Ordovician period, around 450 million years ago. What adaptation helped these starfish find food?

4. 3. Fish This fish lived nearly 400 million years ago. What adaptation gave this fish a new and better kind of mouth?

5. 4. Seymouria Seymouria lived around 280 million years ago during the Permian period and evolved from fishes. What adaptation helped Seymouria go where fishes couldn’t?

6. 5. Stegosaurus Stegosaurus lived during the Jurassic period around 150 million years ago. What adaptation helped Stegosaurus warn away predators?

7. 6. Tyrannosaurus Rex T-Rex lived around 65 million years ago and was among the last of the big dinosaurs. What did T-Rex eat?

8. 7. Pteranodon Pteranodons lived around 80 million years ago. What two adaptations helped Pteranodons catch fish out at sea?

9. 8. Archaeopteryx Archaeopteryx lived around 150 million years ago during the late Jurassic period and were about the same size as a Magpie. What adaptation links Archaeopteryx to modern birds?

10. 9. Mammoth Several species of mammoth lived from about 400,000 years ago to just over 4,000 years ago. What adaptation helped Mammoths defend themselves?

11. 10. Homo ergaster Homo ergaster lived from 1.8 to 1.3 million years ago in Africa. What two adaptations helped Homo ergaster make and use simple tools?

12. 11. Trilobite evolution Scientists know of over 17,000 trilobite species that evolved over 250 million years. Studying them has allowed scientists to learn more about how evolution takes place and how complex structures like eyes developed over time.

13. 12. Human evolution Studying and comparing fossils like homo ergaster helps us understand more of how modern humans evolved from a common ancestor we share with chimpanzees.
