Well-preserved fossil footprints provide the first trackway evidence that Tyrannosaurs may have travelled in packs.
The footprints were found in rocks from northeastern British Columbia and show three Tyrannosaurs travelling in the same direction at the same time, relatively close together. Until now, the evidence for the pack-like nature of Tyrannosaurs relied on the proximity of their bones and trackways of related species.
The footprints also provide important information about the gait of Tyrannosaurs.
