Triceratops Movement

Photo: Computer models of Triceratops walking

Computer models show how a massive Triceratops likely walked. The sequence, which used digital scans of an actual fossil skeleton, was part of a 2001 million-dollar project by the Smithsonian National Museum of Natural History to accurately remount its nearly 100-year-old Triceratops specimen.
