Barnum Brown
Currie became increasingly sceptical of the orthodox belief that large carnivorous dinosaurs were solitary animals, but there was no evidence for his hypothesis that they may have hunted in packs. However, circumstantial evidence came when he tracked down a site mentioned by Barnum Brown that featured 12 specimens of "Albertosaurus" from various age groups. Currie was also involved in the discovery of a bonebed which evidenced gregarious behaviour in the caenagnathoid "Avimimus".
