Mr. Andrews therefore developed the theory that oviraptors were egg thieves , thus the name ovi-raptors. Years later, more eggs were discovered. These eggs contained fossilized embryos of tiny Oviraptors inside, not Protoceratops. The Oviraptors were not egg thiefs after all. Discuss with students the scientific process and how theories are developed, then revised and amended over time.
Older students can research erroneous theories.
Discuss how perspectives can change as theories are confirmed or proven to be erroneous.
