The diminutive dinosaur likely hunted insects, small mammals and other prey, perhaps even baby dinosaurs, said Nick Longrich, a paleontology research associate in the University of Calgary's department of biological sciences. "It's basically a predator of small things," Longrich said. He co-wrote a paper on the dinosaur with University of Alberta paleontologist Philip Currie, which appeared in Proceedings of the National Academy of Sciences.
