High-quality studies of fossil footprints require the proper recording of each track’s three-dimensional shape.  Most publications illustrate tracks using simple line drawings, which are incomplete and sometimes biased caricatures of the true complexity.  Photographs offer much more detail, but poor lighting can cause unclear or incorrect impressions of surface geometry.  Stereo photography can improve a viewer’s perception of depth by presenting a separate image to each eye.  In this paper we discuss the benefits of anaglyph stereo images, which can be viewed with inexpensive red-blue “3-D glasses.”  Using tracks of carnivorous dinosaurs from the Upper Triassic Fleming Fjord Formation of East Greenland as examples, we show that anaglyphs can significantly improve the reliability of spatial information and minimize perceptual errors.
