Tyrannosaurs, it seemed, travelled in packs.
Scientists came to that conclusion after carefully analyzing an extremely rare find — three sets of tyrannosaur tracks found in northeastern B.C.
Tyrannosaur tracks are so rare that this is the first time more than a single print has ever been found in one place.
That made the discovery exciting to begin with, since it allows paleontologists to see how the animal walked, said Richard McCrea, lead author of a new study in the journal PLOS ONE describing the tracks.
