Dromaeosaur dinosaurs hunted large prey in organised packs using sophisticated tactics.
While trackway evidence suggests some theropods may have congregated, evidence for sophisticated pack coordination on hunts remains speculative. Jurassic Park popularised this concept dramatically, but fossil evidence is limited. Some paleontologists propose small family group hunting (parents with juveniles) rather than wolf-like packs. Trackway associations could reflect scavenging aggregation rather than hunting coordination. Neuroimaging of small theropod brains suggests limited capacity for complex group tactics. Some Deinonychus specimens show possible prey association, but interpretations remain contested among researchers.
