|Survival of the Fittest?|
In this lesson plan students will investigate the evidence from modern and prehistoric crocodilians like SuperCroc (Sarcosuchus imperator) to determine the causes of survival and mass extinction at the Cretaceous/Tertiary boundary about 65 million years ago. Students will research and take notes on questions about modern and prehistoric crocodilians, and write papers providing their opinions of why crocodilians have survived so long, including evidence from their research.
