27425 Bakker           Discovered 2000 Mar. 1 by the Catalina Sky Survey.
American paleontologist Robert T. Bakker (b. 1945) was instrumental in developing modern theories about dinosaurs and the warm-blooded behavior of some types of dinosaurs. His book The Dinosaur Heresies (1986) brought these new ideas to the public and lay scientists, and he was a consultant for the movie "Jurassic Park".
