1. Build background.
Show students the photo of paleontologists working on a fossil dig. Ask students to describe what is happening in the photo. Remind students to use observational skills to look for tools, geographic clues, and the work being done.
2. Introduce paleontologist Paul Sereno.
Tell students that scientist Paul Sereno searches for, discovers, and studies fossil remains. Explain that scientists who do this work are paleontologists. Explain to students that on a dig in sub-Saharan Africa, Sereno discovered the fossil remains of Sarcosuchus imperator, a name that means “flesh crocodile emperor”. Ask: Why do you think its nickname is SuperCroc? Tell students that SuperCroc was one of the largest crocodilians to ever walk the Earth. This SuperCroc was 12 meters (40 feet) long—as long as a city bus—and weighed about 8 metric tons (17,500 pounds).
3. Distribute the handout.
Distribute the handout Meet a Paleontologist to each student. Read aloud the introduction.
4. Have students read the interview aloud.
Ask a pair of students to read the adapted interview aloud, with each student playing the role of interviewer or interviewee.
5. Check students’ comprehension.
Check students’ comprehension. Write new vocabulary words on the board and discuss them with students. Have students answer the following questions on a separate piece of paper and then discuss them as a class.
- Why does Paul Sereno think science is fun? (He believes that science is all about discovery and creativity, and asking questions or finding answers that no one else has.)
- Why does Paul Sereno think it is important to study dinosaurs? (Dinosaurs are a connection to the distant past, a time that we can only dream about or think about scientifically.)
- Where did Paul Sereno find SuperCroc? (in Africa)
- What did SuperCroc look like? (Its skull was 2 meters, or 6 feet, long and its body was 12 meters, or 40 feet, long.)
- Why do you think it is named SuperCroc? (This prehistoric crocodile was twice as long and many times heavier than modern crocodiles.)
6. Have students brainstorm questions.
Ask students to brainstorm additional questions they might have about paleontologists and their work. Write the list on the board.
Extending the Learning
Go to the Sea Monsters website to find out more about sea monsters and to find a list of theaters where you can see the film Sea Monsters: A Prehistoric Adventure. Encourage students to look for answers to their questions from Step 6 as they watch the film Sea Monsters: A Prehistoric Adventure.
