This site provides access to QuickTime movies, 'scary' pictures, and sounds of dinosaurs. Included is a movie 'See Triceratops run' and sounds of the 100-million-year Triassic forecast. In order to see the movie and hear the sound you will need an mpeg viewer and an audio player that will play AU files.
