Dino LessonJaculinykus is a small alvarezsaurid theropod from the Late Cretaceous of what is now Mongolia. The name is a reference to the Jaculus, a small dragon in Greek mythology. Like other Alvarezsaurids, Jaculinykus had long legs, and enlarged first digit claws on each hand, which were probably used for digging and tearing. It also had a long tube-shaped snout filled with tiny teeth. These adaptations indicate that it probably had an insectivorous diet, feeding on colonial insects such as termites.
