Updated June 19, 2015 with the addition of the Velociraptor foot.
Deinonychus is the bigger cousin to Velociraptor. Here (Fig. 1) both feet are laid out flat (in vivo it would have been digitigrade) in dorsal view compared to a dromaeosaur track, distinctive for its 2-1/2 toe impressions.
Figure 1. Deinonychus right foot in dorsal view compared to a dromaeosaur track, not to scale. Just added on the right, a Velociraptor foot. Note the differences.
The reduced fourth toe of Velociraptor (or elongated third toe) is the major difference between the two. The trackmaker appears to be midway between the two.
Yesterday was a very big day for visitors.
Thank you Jurassic World on your opening day!
