Far-flung dinosaur? Similar tracks cue study
Paleontologists can’t find differences between tracks continents apart

Dinosaurs were supposed to have evolved. When a new feature evolves, it would be necessary for all the dinosaurs without the feature to die off–or for dinosaur and progeny with the new feature to become geographically isolated from the “parent” group–or else the new feature would simply become absorbed and dissipated within the population. Were the theory of evolution true, this occurrence (death or sudden geographic separation) would be needed for the evolution of all animals to have occurred.

With respect to dinosaurs, this is the main reason that the same dinosaur is given many different names, depending on where its fossils are found. Once the permanent separation of populations of dinosaurs occurred, they should have evolved along separate “lines”. Therefore, a demonstrably similar dinosaur on multiple continents is uncool. Evolutionists generally “solve” these problems with various forms of MANTOSH (Move Along, Nothing TO See Here ;0))…..s8int.com

LARAMIE, Wyoming – It’s a Jurassic curiosity: As far as anyone can tell, the fossilized, three-toed dinosaur tracks in north-central Wyoming and on Scotland’s coast are indistinguishable.

Even after painstaking measurements and statistical analysis, University of Glasgow paleontologist Neil Clark can’t identify any differences between the two sets of 170 million-year-old tracks.

“The fact that the footprints in Wyoming and the ones in Scotland are so similar suggest that they may have been produced by a very similar kind of dinosaur, if not the same species,” he said during a recent phone interview from his home in Glasgow, Scotland.

If the same dinosaur species made the tracks, the discovery would be as earthshaking as a mighty apatosaurus. No one has ever 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.

Now, American scientists are preparing to scrutinize the tracks further. They will use three-dimensional mapping technology that is revolutionizing the study of dinosaur tracks — and promises to enable scientists to make detailed, intercontinental comparisons without leaving their offices.

“What we hope will eventually happen is that there will be this huge virtual archive that can be shared worldwide,” said Brent Breithaupt, a University of Wyoming paleontologist and head of the school’s Geological Museum. “Tracks can be looked at in three dimensions on computer screens and can be rotated around by various researchers — and can be compared.”

Breithaupt doubts the same dinosaur species made the Wyoming and Scotland tracks.

“The tracks are similar, that’s what we know,” Breithaupt said. “It more than likely indicates similar types of dinosaurs living at higher latitudes at some point in time.”

But he’s more than happy to make comparisons.

For one thing, precious little is known about dinosaurs from the Middle Jurassic epoch, when dinosaurs cemented what would be a very long reign on Earth — and when both sets of tracks were made. Scientists have documented very few fossil dinosaur bones from that epoch in North America, making the handful of track sites in the American West valuable for understanding it.

Also, Breithaupt has spent nearly a decade adapting photogrammetry — using photos to create maps and three-dimensional representations — to the study of dinosaur tracks. Now, he’s taking that work overseas.

Most of the tracks Clark examined from the two locations ranged from about an inch long to more than 8 inches, and he compared details such as the length of each toe and the angles between them. He believes the tracks were made by a type of two-legged, carnivorous dinosaur called a theropod.

One set is from the area of Red Gulch in arid north-central Wyoming, where it looks like a flock of Big Birds ran across freshly poured concrete. The others are near the shore of the Isle of Skye off Scotland’s west coast.

Wyoming and Scotland were much closer together in the Middle Jurassic, before continental drift opened up the Atlantic Ocean between what is now Europe and North America. Even so, the tracks were roughly 2,500 miles (4000 kilometers) apart when they were made — about the distance between New York and Los Angeles.
