Erratic speculation doesn't solve Stonehenge mysteries.

A STONEHENGE mystery has been solved, according to an expert, after a "smoking gun" discovery was made to provide the "missing piece" of the puzzle.

"A giant bluestone erratic just discovered near Mumbles, on the south Gower coast, has been hailed as one of the most important glacial discoveries of the last century since it proves beyond doubt that the Irish Sea Glacier was capable of carrying large monoliths of dolerite rock from Pembrokeshire up the Bristol Channel towards Stonehenge."

And so on...

Green dolerite erratic carried on Irish Sea Glacier from Preseli to Mumbles c 19000 years ago. Stone such as this was used to construct Stonehenge.

But seven months after this publicity barrage the analysis of the erratic still hasn't been made public. We don't know what the rock is geologically, or where its likely source is  It may well be a bluestone from Pembrokeshire but there is no proof of that yet, no data supports it is the same as Stonehenge stone. It is intriguing and may be significant but until the hard work is done it is just a fantasy to claim it has solved a Stonehenge mystery.  

As another Stonehenge scholar has said about a similar case:

"we have a duty to mull over this question: "How is it that a narrative so unsupported by hard facts and so far removed from reality was accepted by so many people as one of the great archaeological finds of the century?...Apparently nobody noticed that the article was seriously deficient in hard data and overloaded with speculations and rash assumptions...So they all went full steam ahead, gloriously oblivious to the fact that they were spreading a wildly irresponsible myth dressed up as serious research. Were they all stupid, or were they all just too busy and too swept along by the own hype to seriously examine the content that they were feeding to the public?..

Due diligence definition: “the care that a reasonable person takes to avoid harm to other persons or their property”

 Are people actually "harmed" by those who misrepresent or mislead and who make outrageous claims based upon very flimsy evidence? Of course they are. It's called deceit or fraud, neither of which should be tolerated in any civilised society. ."
