A group of North America's smallest known carnivorous, non-avian dinosaur, estimated to weigh 1.9 kg, the recently described Hesperonychus elizabethae prowls the shores of a shallow Albertan lake in the Campanian Late Cretaceous (75 million years ago) while a much larger theropod, Gorgosaurus libratus, approaches from the opposite shore. Hesperonychus elizabethae was a genus of small, carnivorous dromaeosaurid dinosaur.
