Tracks Of Sailing Stones & Dinosaurs Found Preserved Under An Ancient Slab In Portland

The Scientists found marks of the Sailing Stone across the desert landscape in Scotland. Along with stones, the massive mammal tracks noticed by scientists. The land’s slab scanned by them and have created the 3D-printed models of those sections. It reported that these are more than 200 million years old. The tracks belonged to dinosaurs called Anchisaurus. According to a paleontologist at the Lamont-Doherty Earth Observatory at Columbia University, Mr. Paul Olsen says that the dinosaur foot-prints discovered 100 years ago. Footprints sized 11 feet long. But during that study, some portion of land remained unexamined. Thus includes a series of marks and grooves.

According to research, the sailing stones are the moving stones. It is a geological phenomenon, in which rocks move from one place to another without any involvement of humans or animals. It occurs due to long ice sheets with some millimeters of thickness starts to float during sunny days. It happens after winter, and because of the temperature difference within both seasons tends rock to slide over the surface. When it moves from one position to another, it produces marks and tracks on that specific land surface. The researchers found that ancient slab evacuated from a quarry in Portland. During that period, the broad masses of sulfur spewed on the surface, and It happened during the cooling period after the explosion and the irruption of the volcano. Another reason behind the sailing stone is Microbial mats, which are the coatings of microbial goo with smaller thickness.

The research includes the analysis of the marks belongs to Anchisaurus. These dinosaurs lived during the early Jurassic era. Its fossils found in the red sandstone of Portland. The study defines the difference between significant track belongs to dinosaurs and the sailing stone marks. So these are the facts unveiled during the annual meeting of the American Geophysical Union (AGU). The research undergoes with the sizes patterns and other characteristics of tracks and marks.
