Was Triceratop's stance
erect or semi-erect?
It was definitely not sprawled like older representations.
From the Scientific American Book of Dinosaurs: Ceratopsian trackways indicate that the hands were separated by two hand widths from one another; hindfeet nearly touched midline.
Below is an illustration from Dinosaur Tracks by Lockley and Hunt, 1995. The tracks are those from the Laramie formation.
Note: the illustration above shows very little padding on the front foot tracks compared to the back feet tracks. This is opposite of what is represented in the Smithsonian's sculpture.
