This video, recorded in Russia, says about itself:
The story of the discovery of the world’s most complete baby mammoth, as told by the man who found her.
Translated from Blik op Nieuws in the Netherlands today:
The bone probably came from the North Sea and beached. Then someone found it and probably left it behind in the dunes.
The bone is a carpal bone from a mammoth’s foreleg.
