They’ve gotten much better since Piltdown. Now, entire species are created from a bone fragment the size of a dime.
Ahh, but you forget the fragment of a pig's tooth that was found in the US in the late 1800s and touted as coming from the "missing link". Drawings of the "man" and his "family" were made, until someone unearthed the rest of the pig. It was an ancient pig, but a pig nonetheless.
