Dino Gangs: solitary, communal, or cooperative hunting in tyrannosaurs

The Discovery Channels in the UK and the US recently have aired documentaries called “Dino Gangs” that follow dinosaur paleontologist Philip Currie around the globe (Alberta, Mongolia, Indonesia, South Africa, Great Britain), including little Athens, Ohio, the home of Ohio University. “Dino Gangs” addresses Currie’s theory that tyrannosaurs hunted as cooperative, social packs. Phil and the film crew from Atlantic Productions were here to talk with me about my work with Ryan Ridgely on tyrannosaur brains and sensory capabilities…basically whether tyrannosaurs had the mental wherewithal to pull off pack hunting. Phil Currie and his collaborators have published a few articles that have alluded to the possibility of coordinated, social, pack hunting, mostly notably his 1998 article in Gaia. My goal here is neither to evaluate the nuances of his arguments (e.g., the taphonomic issues) nor to address the media hoopla from the folks at Atlantic, the same folks who brought us Darwinius  and Predator X (check out Brian Switek’s thoughtful response). My goal is simply to relate what went on here in Athens and to clarify how I think tyrannosaur neuroanatomy fits into the argument.
