1423:. The Newark Supergroup footprints show digits II, III and IV, but no trace of the shorter digits I and V which would likely have been present in a dinosaur of this stage. The outer two digits would have been stubby and ineffective, not touching the ground during walking or running. Despite losing most of their effectiveness, dinosaur evolution had not yet removed these digits to fully streamline the foot. This is known because rare specimens are found with traces of these outer digits. Digits II, III and IV have 3, 4 and 5 phalanges respectively, giving 437: 1531: 145: 1517: 127: 1456: 1401: 409:
footprints are characteristically three-toed (tridactyl) and range from 10 to 20 centimeters (or 4 to 8 inches) long. Though the tracks show only three toes, the trackmakers likely had between four and five toes on their feet. While it is usually impossible to match these prints with the exact
