Did a three-foot-tall predatory dinosaur species
As Brent Breithaupt of the University of Wyoming has noted, though, the tracks more likely mean that similar dinosaurs were living at similar latitudes at about the same time. A 2,500-mile migration, especially across an ancient sea, is a little hard to swallow and would require extraordinary evidence. Indeed, dinosaur tracks are usually given their own scientific names as they usually cannot be attributed to a particular species with certainty (that is, unless we find a dinosaur that literally died in its tracks). The scientists will continue to compare the tracks from Wyoming and the Isle of Skye, but a lot more evidence will be needed to confirm the idea that these theropods were migrating.
