Parallel dinosaur trackways can be used to infer that their makers were group animals. In this study, we evaluate whether Early Jurassic theropods in eastern North America were gregarious by examining trackway orientations in different paleoenvironments. We show that trackways lack preferred orientations in playa lake deposits and that parallelism is restricted to permanent lacustrine environments. These results suggest that, rather than group activity, trackway parallelism resulted from the animals interacting with their environment (i.e., they followed the shoreline of a permanent lake).
