Factual error: When Hooper sees the hole in the hull of Ben Gardner's boat, he uses his knife to pry out the shark tooth. The tooth is located at the bottom of the hole, with its flat root side stuck deep in the wood and its pointy side facing up. It is completely impossible for the shark's tooth to become wedged in the wood this way, while he takes a nice bite out of the wood hull. (00:49:15)
Suggested correction: When Hooper uses the knife to pry to tooth out, it took very little effort, suggesting that the tooth wasn't wedged into that spot, but merely just resting in that spot.
The shark tooth was inserted into the wood by the prop crew with its flat root side down, which would have been impossible to have occurred during the attack on the hull. As to the statement that the tooth was "merely just resting in that spot" then Hooper would not have needed to use the blade to remove it from the wood, plus the fact that since it was underwater it would have floated away during the hours after the attack. But it did not float away, so it must have been at the very least snugly fit into the wood hull. Still impossible.

The original mistake says that the root of the tooth was embedded In the wood. Not possible since it should be the sharp end in the wood and the root showing on top (as described in the mistake).
