The Lost World Bestiary - Notoraptor

One of the more notorious smaller predators of the plateau is Notoraptor rapax, a rather typical dromaeosaur, which reaches 2.5 meters long. These dinosaurs generally travel in small family groups, which hunt cooperatively to some extent, though calling it a “pack” might be a stretch. A singleton can easily kill a man one-on-one, but a whole group is a handful for even a band of explorers or Indians. Generally preferring well-vegetated areas with extensive cover, they most usually feed on other dinosaurs, be they adults of middle-sized species or the calves of larger ones.
