If real, this is an amazing piece of footage! It certainly does look like a woolly mammoth, and the coloring matches hair samples that have been found. These days we have to be careful about jumping to conclusions, however, since very convincing hoaxes can be created with cgi software (think Jurassic Park). Some have even said it's just a bear with a large fish in its mouth, making it look like it has a trunk (which upon repeated viewings seems a distinct possibility). And The Sun newspaper has been known to feature its share of hoaxes and questionable material. But we're keeping an open mind on this one since it is so potentially amazing! Reportedly, there have been unconfirmed sightings of mammoths in this region over the years, and this could be confirmation!
