Time Traveller

You climb into the machine and set it for the cretaceous period, trying not to think about all those dinosaur films you saw as a kid. You are not thinking of staying long in this time, as you are not armed, and this is probably the most dangerous time you are going to.

You press the panel on the machine and feel sick as the machine lurches and comes to a halt. Warily, you open the door of the machine and peer out onto a massive rolling plain. As usual, this isn't a good enough picture, so you must at least find a small dinosaur to take a picture of. You can head off in any direction, so which will it be?
