Be sure to place your answers on the line below the question and then highlight your answer in yellow, color or underline your answers. First video: This 14 min. video is about T Rex and shows how paleontologists work on theories.
1. What is the name of the male paleontologist featured in this video?
2. Why does he only have a high school diploma even though he spent 7 years at the University of Montana as a student? (Side note - he has become a nationwide advocate for people who deal with this academic disability.)
