 Mathilda. ( The map of main finds of mammoths in Siberia )
  At once, very long ago, at the end of the last Glacial Epoch, the narrow twisting river Oyesh (running into the river Ob hardly to the north of Novosibirsk)  punched a road among swampy plaines of the Ob’s right bank. Year by year it absorbed water of neighboring lakes and swamps, draining neighbourhoods. It’s channel gradually became deep, the bank became more higher and abrupter. When Oyesh was still small-sized stream, on it’s overgrowned by vehement green banks grew fat the herds of mammoths. The marshy and swampy place concealed many dangers, especially in spring, during high waters and floods. Many animals who had not abandoned these places timely, had parished in water. Somebody finds remains of mammoths here up to now. Especially there is a lot of mammoths bones in the area of the village Vahrushevo. 

Skeleton of female mammoth Mathilda,
found  on Novosibirsk area.

  In the summer in1939, as usual, the village boys  swam in the Oyesh . Suddenly they   noticed, that from a coastal breakaway jut out the direct brown radical. They decided break it off, and then pulled out from the ground the slightly curved tusk of a mammoth. They already heard about the fossil of giants lived in these places at once, and they told about the find to their teacher, who send information about it to Novosibirsk. In some days the employees of the Novosibirsk Regional Study Museum arrived in Vahrushevo. The excavation  began on the bank of the Oyesh with the participation of boys. In some days the whole skeleton of a mammoth is extracted. It’s remains were carefully cleared and sorted, and then, by examining the bones, museum employees determined, that the boys were lucky to detect the whole skeleton of a mammoth female, occurring very rarely.
  Bones were transported in Novosibirsk and are handed on the storage to the museum department of a nature. The skull with short direct tusks  decorated an exposition, and remaining bones are located in storehouse. The World War II was soon begun. Museum employees packed mammoth female’s bones into boxes and delivered them for long storage together with other exhibits.
  Only in 1974 the remains of mammoth's female were extracted from storehouse. It was decided to construct the whole skeleton. For the bones restoration and skeleton assemblage the employee of the History Institute of Siberian Branch of Sciences Academy known siberian scientist N. Ovodov was engaged. It is not easy to make the whole skeleton of separate bones. At first it is necessary to clear the bones of dust, then for some days to impregnate them in the special preserving solution, then to paste the bursted and broken parts together . But that is not all. Usually small-sized bones are not saved, therefore it is necessary to produce the replacement for them - the copy. And only then, after careful measurements of all bones, it is possible begin to make an iron frame, on which the skeleton will be kept. For some months N. Ovodov with his voluntary assistants - employees of various institutes of Novosibirsk Science Centre - made the skeleton's reconstruction. When the whole exhibit already stood in the hall of museum, it have being clarified, that the scientists have named mammoth female as Mathilda. Nobody remembers when and how it was happened, but the name was pleasant and lived. Everyone names this exhibit so up to now.
