Experts are baffled over the discovery of fossilized, three-toed dinosaur tracks that have been found in both north-central Wyoming and on Scotland's coast, The Associated Press reported.Neil Clark, a paleontologist at the University of Glasgow, has not been able to identify any differences between the two sets of 170 million-year-old tracks even after a series of painstaking measurements and statistical analysis.He told AP that since the footprints in Wyoming and Scotland are so similar, they may have been produced by a very similar kind of dinosaur, if not the same species.Paleontologists have never been able to say for certain that the same dinosaur species was responsible for fossil tracks discovered at separate locations, much less thousands of miles apart.But now, using three-dimensional mapping technology that is revolutionizing the study of dinosaur tracks, American scientists are preparing to scrutinize the tracks further.The technology will enable scientists to make detailed, intercontinental comparisons without leaving their offices.Brent Breithaupt, a University of Wyoming paleontologist and head of the school's Geological Museum, said they hope to help establish a huge virtual archive that can be shared worldwide."Tracks can be looked at in three dimensions on computer screens and can be rotated around by various researchers - and can be compared," he said.However, he doubts that the same dinosaur species made the Wyoming and Scotland tracks."It more than likely indicates similar types of dinosaurs living at higher latitudes at some point in time," Breithaupt said.Experts say little is known about dinosaurs from the Middle Jurassic epoch, when the giant lizards cemented what would be a very long reign on Earth - and when both sets of tracks were made.
