July 2, 2003: Gerald McSorley, a Scottish pensioner, found a fossilized section of a plesiosaur vertebrae when he accidentally tripped and fell into the loch. Nessie enthusiasts speculated the fossil might have come from an ancestor of the monster. But subsequent examination revealed the vertebrae were embedded in limestone not found near Loch Ness, and the fossil showed signs of having recently been in a marine environment. In other words, it was clear the fossil had been planted at the loch.

March 2005: Two American students visiting Scotland claimed to have found an enormous tooth (possibly belonging to Nessie) lodged in the carcass of a deer along the shore of the loch. However, (so they said) a game warden who happened to be passing by almost immediately confiscated the tooth from them, though not before they got a few pictures of it. The students subsequently created a website to publicize their find and lobby for the return of the tooth. But animal experts identified the "tooth" from its picture as the antler of a roe muntjac deer. The website and accompanying story then turned out to be a publicity stunt for a horror novel by Steve Alten titled The Loch.
