Do you think that because one guy once got carried away, and was quickly corrected by his Scientific peers, that all fossil finds are “one tooth”?
Don't be silly, it wasn't "just one guy".
There's also the case of the OBVIOUS fraud of attaching a ape jawbone to a human skull fragment, then filing down the canines and presenting that as a transitional form. Once the fraud was exposed, it was obvious that anyone looking at the "original" had to be in on the fraud as well.
