Theropod imagery is haunted by solitary, drooling brutes like T. rex gnawing their way through herds of herbivores. But is that really all there was to it? Hunting in packs and armed with grasping claws and slicing teeth, small, large-eyed, intelligent, and agile theropods were likely the real nightmare terrors of Mesozoic landscapes (Figure 9.6).
Non-avian theropods have been collected from virtually every kind of depositional environment. In most instances, skeletal remains are found in isolation, the delicate, hollow bones fragmented. However, bonebeds of single thero-pod species are also known (see "Social behavior," below).
