"Deinonychus" fossils have been uncovered in small groups near the remains of the herbivore "Tenontosaurus", a larger ornithischian dinosaur. This had been interpreted as evidence that these dromaeosaurs hunted in coordinated packs like some modern mammals. However, not all paleontologists found the evidence conclusive, and a study in 2007 by Roach and Brinkman suggests that the "Deinonychus" may have actually displayed a disorganized mobbing behavior.
