But based on recently discovered footprints in Alberta, Canada, paleontologists now suspect the tactic isn’t a modern evolutionary development—even dinosaurs may have participated in similar multi-species herding patterns. The findings made at the Dinosaur Provincial Park UNESCO World Heritage Site were detailed in a study published in the journal PLOS One.

While there, they discovered a set of at least 20 full and partial dinosaur footprints preserved in a roughly 312-square-foot section of sediment. Regardless, the confirmation of mixed species dinosaur herding behavior represents a major moment in paleontology, one that could soon open up new possibilities and research opportunities.
