Description
Although the skull of Junggarsuchus shares many characteristics with those of modern crocodilians, it is morphologically intermediate between sphenosuchians and mesoeucrocodylians. As in other sphenosuchians, the limbs of Junggarsuchus were adapted to terrestrial locomotion (movement on land), rather than semi-aquatic locomotion seen in living crocodilians. These adaptations include: a vertically orientated upper arm bone, ball-and-socket shoulder joint, and a functionally tridactyl (three-fingered) hand.[1]
