Even during the last ice age, when temperatures often reaching down to -20 degrees celsius, were our ancestors able to survive and keep warm.
But our scientists have apparently also been busy with something else - researchers have discovered a mysterious circle of mammutknogler.
There is talk on the discovery of one of the oldest and largest cirkelkonstruktioner from the ice age made of mammutknogler.
The writing media, Science Alert, according to Science.dk.
Mammutfossilerne was found on a Russian delete known as Kostenki 11, which is located about 500 kilometers south of Moscow.
By using carbon-14 dating has a new study, which is published in the akedemiske journal Antiquity, dated the construction to more than 20,000 years old.
It also means that the british archaeologists from the University of Exeter have discovered the so far oldest knoglecirkel, which is built by modern humans on the Russian plain.
- Archaeology shows us more about how our ancestors survived in this desperately cold and hostile environment at the peak of the last ice age. Most other places at similar latitudes in Europe, had been abandoned at this time, however, these groups had managed to adapt to find food, shelter and water, say the palaeolithic archaeologist Alexander Pryor from the University of Exeter in a pressemddelelse, writes Science Alert.
Knoglecirklen measures 12.5 meters across and seems to be built almost entirely of mammutknogler along with some broken bones from, among others, reindeer and bears.
According to Science Alert has archaeologists identified 51 us and 64 individual skulls from mammoths, which were used to construct the walls in a 9x9 meters building.
On the outside of the circle, there were also found three large holes filled with big mammutknogler.
The british research team also found kulfragmenter in knoglecirklen, which confirmed that there were people present who used wood and bones as fuel.
It is only the second circle of mammutknogler, where træfyring have been identified, and this newfound circle is about 5,000 years older than the other.
Scientists are still in doubt as to what this knoglecirkel has been used for, and what has brought our ancestors to the site.
- One possibility is that the mammoths and the people could have come to the area because it had a natural source, which would have provided liquid water through the winter, which is rare in this period of extreme cold, tells Alexander Pryor from the University of Exeter in the press release.
