Types of Tracks

Bipedal tracks are by far the most common. They contain left-right sequences of similar looking prints. All bipedal tracks contain three major marks and thus are commonly called a 'three-toed track.' It's interesting to note that most bipedal dinosaurs had four toes on each foot, with one toe held in an elevated position at the back of the foot.

The dinosaurs that made bipedal tracks are classified in two major groups: theropods (bipedal meat-eating dinosaurs) and ornithopods (bipedal plant-eating dinosaurs). Theropod tracks typically exhibit long and narrow toe impressions with thin claw marks. Ornithopod tracks are wider and more rounded than theropod tracks with more hoof-like claws.

Quadruped dinosaur tracks are much less common than bipedal tracks. Quadruped tracks generally show rear and front foot tracks. The rear prints are generally larger than the front prints. The feet of quadruped dinosaurs usually have four or five toes.
