It was a fact with the incredible Takingadumposaurus AKA Poopysaurus Hoax until it turned out to be a fraud. Same with the next one. aaaaaaaaaaaaaaaaand a few others.
I called it that back then, because even I, totally unqualified to be even called an amateur, couldn't figure out why there was this darker rock between his legs, like it took a dump when it died,,,
Turned out the reason why was because that stone not only did not come from the same fossil, not the same species, not even the same rock formation. It came from a few miles away.
