theropods. Theropods are inevitably portrayed as active, voracious, and vicious predators that ruthlessly pursued and killed their prey. Many movies show theropods running in packs, which suggests that they had greater activity levels and energy requirements than normal modern reptiles and behaved more like mammals or birds.

What fossil evidence supports that any, let alone most, theropods were predators? In contrast, which of the theropods could have been scavengers? Were some possibly omnivores or even herbivores? Finally, what fossil evidence answers questions about their activity levels and social behavior, and how do these compare to modern mammals or birds?
