Woolly Mammoth VideoRemember that cool woolly mammoth video that was making the rounds last week?  Well, as suspected, the video was a hoax.

The video became an instant hit on the web, with many Bigfoot and Loch Ness Monster buffs hoping the footage was authentic.

Unfortunately, it wasn’t.

Ludovic Petho is the man who filmed the video…although, at the time, there was no woolly mammoth was present, he says.

It seems someone went back and digitally altered his footage, inserting the creature that’s been extinct for thousands of years.

Petho filmed the river scene while he was hiking in the mountains as part of a video project he’s working on about his grandfather’s escape from a Siberian POW camp back in 1915.

The footage may one day end up being used in a documentary film.

“I don’t recall seeing a mammoth; there were bears, deer, and sable,” Petho said. “But no woolly mammoths. I had no idea my footage was used to make this fake sighting.”

Petho added that his original video footage had been available on YouTube since July 2011, depicting the exact same scene, without the faked mammoth in it.
