Smallest Known Dinosaur in North America Discovered

CNN has a story about the discovery of Hesperonychus elizabethae, a dinosaur that was slightly smaller than a house cat. As relayed in the story:
Hesperonychus elizabethae, a 4.4-pound (2-kilogram) creature with razor-like claws, ran through the swamps and forests of southeastern Alberta, Canada, during the late Cretaceous period, the researchers said.

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.
