The approximate age of the remains is 40-50 thousand years. This is the largest and well-preserved finding that were managed to find according to the head of the expedition section of the Sverdlovsk regional branch of the Russian Geographical Society (RGS) Sergey Kondrashin. Divers from Ekaterinburg have been exploring the bottom of the Tobol for 14 years. Every year the river presents them with some gifts: the hardened teeth of sharks, the remains of an ancient bison, the bone of a cave lion. One theory is that this place was formed because the river made a bend there and the carcasses of old and sick animals were washed thitherward.
"At the bottom of the Tobol River, we found a 25-kilogram thigh-bone of the mammoth, that was preserved almost perfectly, we didn’t have this kind of findings before. While it was in the study by a paleontologist and on preservation, we didn’t show it to anyone and now we will hand over it to one of the museums of the Urals, "- said Kondrashin.
No one investigated this place of an abnormally large accumulation of paleontological fragments due to the strong flow in this part of the Tobol River, where divers found the so-called "bone lens". Among experts, it even got the name "The Jurassic Park".
