A case study of how an hypothesis or theory in science is succeeded by better explanations -- how scientific knowledge accumulates or advances or grows.

Why no dinosaurs today? The case explains the succession of hypotheses going from (1) global catastrophe in the early 19th century to (2) Darwin's gradualism in the early 20th century to (3) asteroid or meteor impact today. (4) A revision of the 3rd hypotheses that is forming now. it explains how each theory replaced earlier theories.

The use of models in science is also addressed.
