Fossilized remains of mammoths often can be found in Russia, but there are a few places where the traces of these ancient giants. One of these is the desert of White Sands, located in the American state of new Mexico. Here, in the vast area of about 581 square meters, a year-round lies consisting of gypsum crystals white sand, which is very similar to snow. On this site and then found traces of Colombian mammoths, which due to living in warm conditions, had much less hair than other dogs of Eurasia. Recently, paleontologists from Cornell University (USA) managed to find not only their tracks but also removal of their ancient people.
According to scientific journal PLoS one, the discovery of 12,000-year-old traces of ancient hunters, paleontologists didn’t even have to dig. The discovery was made in the course of scanning the surface of the American desert with the help of a device called ground penetrating radar. It allows you to look under the ground without excavation and is commonly used to detect damage to rail lines. Sometimes it is used in the course of archaeological works and, as it turned out it effectively and with the discovery of fossilized traces.
How does the GPR?
GPR able to work on different test media, whether soil, rocky mountains or even fresh water. The three main parts of this device are the transmitting and receiving antenna, the recording unit in the form of a laptop and the control unit, which is a variety of wires.
By the way, using a similar technology in Egypt was found sunken temple and the treasure ship
The principle of GPR is almost the same as other kinds of radars. In the studied environment, the device sends electromagnetic waves that are reflected from near the bottom of the solid objects. Based on the back data, scientists can create a view on the form located at the bottom of the object.
Went ancient people and animals
Using ground-penetrating radar, scientists have found traces of Columbian mammoths and hunted them ancient people. Such discoveries are extremely rare today, so discovered 800 meters of the tracks are very interesting to researchers. At the moment, besides the fact that hunters could hunt mammoths in the hope to get meat and fur, they can’t tell you anything interesting. But the prospects for the use of ground penetrating radar in paleontology is very large.
Detectable underground tracks can tell not only about the movements of our ancient ancestors and the ancient giants, but also about many other aspects of their lives. For example, fossilized prints perfectly illustrate the size of the feet, especially the gait, speed, and even the interactions of people and animals.

According to paleontologist Lisa Buckley, who was not involved in the above study, but he knows about the results, the use of GPR in the study of the ancient world is very large. Even if her colleagues will not be able to find the remains of people and animals, about their life and characteristics of the body structure can tell the traces left by them.
