Inscription. This illustration was created to match the view from where you are standing right now, and several of the animals pictured are placed according to actual trackways that can be seen from this vantage point. Can you see where they left their prints? Where do you think they were headed? While we may never know what the rest of their lives were like, one thing is certain: the trackways you are looking at each record the movements of individual animals that lived in the distant past.
