I think this might be relevant to what paleofood was, although it is  
beyond my present level of comprehension.
It's from an ebook "The Secret History of the World..."



"No one has ever made a systematic count of the megaliths, but the  
estimate goes
beyond 50,000. It is also admitted that this figure represents only a  
fraction, since
many have been destroyed not only by the forces of nature, but also by the  
wanton
destruction of man.
Even though there are megalithic monuments in locations around the world,
there is nothing anywhere else like there is in Europe. The megaliths of  
Europe
form an enormous blanket of stone. Great mounds of green turf or gleaming
white quartz pebbles formerly covered many of them. The quartz is, of  
course,
electrically active. The megalithic mania of ancient Europe is:
Unparalleled indeed in human history. For there has never been anything  
like this
rage, almost mania, for megalith building, except perhaps during the  
centuries after
AD 1000 when much the same part of Europe was covered with what a monk of  
the
time called a "white mantle of churches."
The megaliths, then, were raised by some of the earliest Europeans. The  
reason that
this simple fact took so long to be accepted was the peculiar inferiority  
complex
which western Europeans had about their past. Their religion, their laws,  
their
cultural heritage, their very numerals, all come from the East. The  
inhabitants,
before civilisation came flooding in from the Mediterranean, were  
illiterate; they
kept no records, they built no cities. It was easy to assume that they  
were simply
bands of howling half-naked savages who painted their bodies, put  
bear-grease on
their hair and ate their cousins.
The whys and wherefores of this "megalith mania" are still under debate.  
The
fact is: you can't date stones. Yes, you can date things found around  
them, or nearthem, or under them, but you can't date the stones.
The interesting thing about the megalith builders is that the peoples who  
were
able to perform these utterly amazing feats of engineering are still, in  
most circles,
considered to be barbarians because they did not build cities, engage in
agriculture, develop the wheel, or writing. Yet, they did something that  
clearly
cannot be, and was not, done by "civilized" peoples who did all of those
"civilized" things. They had some sort of "power" that we cannot replicate  
and do
not understand."
