A depth map of a stegosaurus track from Morrison, Colorado. The depth of the track can help indicate which part of the foot was bearing weight during the step.

Building the model

Scientists use photogrammetric software to create and manipulate 3D models of the stegosaurus trackways. This image shows how multiple camera angles combine to build the 3D model.
