'Ghost' footprints from the last ice age could help track movement of dinosaurs

Researchers from Cornell University, with help of a special of rar, recently discovered footprints that were hidden since last ice and what lied underneath m. fossilised footprints revealed a great deal of information in relation to how human beings and animals co-existed around 12,000 years ago.

'Ghost' footprints

researchers said that y initially never thought of looking under fossilised footprints but it turned out that fossil h recorded effect of animal's weight and momentum. researchers also ded that study gave m chance of studying biomechanics of animals that went extinct millions of years ago. 

According to reports, researchers h analysed footprints of human beings, mammoths, and sloths at White Sands National Monument in New Mexico. Using GPR (Ground-penetrating rar), team was able to analyse approximately 96% of human footprints alongside all big animal footprints.

However, researchers feel that re are bigger implications than just case study.

study's le researcher, Thomas Urban, stated that GPR technique could be used to analyse or fossilised footprints found in different parts of world, potentially including those of disaurs. Thomas furr ded that y h successfully tested technique at multiple locations within  White Sands National Monument. 

Sturt Manning, a co-researcher, said that se 'invisible' footprints can remain hidden for a short period of time after rain and with conditions right, footprints can be recorded, tracked and analyzed in 3D to reveal identity of Pleistocene animal and human interaction alongside history in unique ways.

What is GPR?

GPR is a method that does t destroy fossils and gives an opportunity to researchers to gain access to information without need of an archeological excavation. sensor, which is like an antenna, is dragged over marked surface simultaneously sending rio waves into ground and signal n bounces back to give a pictorial representation of what exactly is underneath surface.
