If it was a “pretty significant find”, we would be reading about it in “pretty significant” scientific journals. If it was a “pretty significant find”, we wouldn’t have a difficult time finding many mentions of it online. (If nothing else, it would be cited by every Young Earth Creationist website as their very best evidence against evolution!) Instead, it appears that the skull has only been reported on an obscure and definitely insignificant website where anybody can post anything. That doesn’t sound significant to me.
Lie detectors are junk science. That’s why they are rarely admissible in court trials. Polygraphs don’t detect lies. They detect various bodily responses to stimuli, including stern questioning. If a person BELIEVES that a polygraph detects lies, they MAY in some cases exhibit stress responses which MAY in SOME cases lead observers to QUESTION why the subject is showing stress reactions. That’s about it. If you investigate the use of polygraphs in controlled studies where “lie detection” was put to the test, you will discover what I just explained and you will learn why they have such a poor reputation.
A skull spotted on top of some dirt is a find without certain provenance. Period. End of story. The opinions of equipment operators is irrelevant. Adding “lie detectors” to the story only makes it more comical and last resort desperate, not more certain.
How do we know that some prankster didn’t put a human skull into the bucket of the excavation machine while the crew was at lunch? If that sounds far-fetcher, it shouldn’t. There have been several such practical jokes which have wasted the time of paleontologists who were visited by excited crews who thought they were going to make a fortune selling their “discovery” to a museum, only to be told by the paleontology professor a few days later that the clay packed inside of the skull contained a Coca-Cola bottle cap. (The fact that a victim of a practical joke might pass a lie detector test is irrelevant.)
I come from an area of the Midwest where Indian mounds and ancient grave sites are common, I knew farm families who had Native American relics and even bones which had been passed down through the generations of their family since pioneer days. Typically, a great great grandfather had dug up a small Indian mound in hopes of finding “treasure” inside but found those items instead. And during the Depression years, some families thought that they might be able to make more money from their finds if they placed all but one or two relics back into the mound and took the others to the nearby university extension campus. If they were lucky, the archaeology professor would send a couple of graduate students to the farm in order to evaluate the site for a potential excavation. (Of course, they hoped the university would pay them a “rental fee” while using the land.) What the grad students usually discovered was a hopelessly disturbed hole in the ground with limited archaeological value. My favorite story was about the grad student who quickly found the arrowheads that had obviously been reburied by the family—alongside a small steel garden spade and the lost wallet of the teenager whose dad had told him to “seed” the site with the arrowheads. It was later discovered that the arrowheads reburied in the mound were from a different civilization and period than the one known for building such grave mounds, so apparently grand-dad had forgotten where his father had found the arrowheads. There again, lie detector test results wouldn’t change the fact that the excavation site and the provenance of the items were beyond accurate determination. (The Paluxy River Tracks also have their own Depression Era stories where family members hoped to convert “manufactured finds” into quick cash.)
Of course, all of this is of little more than just anecdotal amusement. I’m less interested in a tall tale about an alleged human skull in some particular coal strata than in why one NEVER finds ANY angiosperm’s pollen in ANY ancient strata on the entire planet where one finds fossils of dinosaurs and trilobites, for example. If scientists are wrong and the earth is just a few thousand years old, doesn’t that seem odd?
