Sauropods have long been depicted as large, lumbering vegetarians that we were taught lived about 150 million years ago. Until recently, we thought of their outsides as pretty much elephantine, thick skin etc., but a discovery was made in 1992 that changed that idea a bit. More on that in a moment.
The late Dr. Javier Cabrera has collected over 11,000 stones from Ancient Peru, from around the river of Ica, depicting all aspects of the ancient Peruvians culture. The cover from the idols they worshipped, to successful trepanning (brain surgery of the nature of drilling a hole into someone's head with which to drain excess fluid.) to people riding, hunting, and being eaten by dinosaurs. The authenticity of the trepanning has been verified by the finding of skulls with healed bone that would suggest succesful surgery. I'm no expert on that stuff, but that's what i've read in many different places. Anywho, this is about dino's not surgery. The stones depict Triceratops, Stegasaurus, Pterosaurs, Allosaurs, and Sauropods (i would say they look more like Diplodocus). The Diplodocus are all depicted with dermal frills going down their back. Which I found to be quite interesting.
The Ica stones have been considered fraudulent by the general "scientific community". Back when the good doctor was gathering these rocks, mostly from a local farmer, the government stepped in and stated that if these were truly artifacts, that they belonged to the government and that they were to confiscate them. So the farmer (after some prodding, I have read) admitted to making them all, so as to avoid the trouble of being an illegal artifacts dealer etc. He stated he made them himself and copied the pictures from old magazines, books and other media. That was enough for the government and "scientific communitity". Especially since depicting man and dinosaur in the same place & time seriously shook the evolutionary theory (read: hogwash). But hold on.
First off, there are over 11,000 of the damn things. The farmer would have to invest a good 20 years into this project, without anyone finding out. Second, a few of the rocks show a ceasarian section being done, as well as the brain trepanning. Now along with all the other dinosaurs and other pictures, what extensive library did this man have access to with which to copy all these pictures? Maybe he just knew about them, if they were doing it 2000 years ago (in that area), then its possible they still did it locally. But there's more. The way rocks are made with engravings is like this: rocks get covered in a type of "varnish", a black covering from bacteria and such thats died over a long period of time. This gets scraped off, and the lighter rock underneath is shown and poof: engraving. The nice part is, this varnish stuff is made from dead bacteria, so it can be carbon dated (which isn't entirely accurate either, but it gives a general idea). These Inca stones have an extra bit of varnish, on top of the engravings! This means that the original engravings had to have been done about 2000 years ago, or that the farmer has found a way to cheat time.
In 1992, in Geology Magazine (December, v.20 no. 12) some fossilized skin of a sauropod shows that a median row of spines was present over the tail and continued up along the back and possibly the neck. Many conical/spinelike elements were found throughout the quarry (Howe quarry in Wyoming, a good place to find sauropod peices) and it is definite: sauropods had frills going down their backs. Funny how only we knew about it in 1992, but it was drawn that way back about 2000 years ago. I'd say thats more verification of these stones and thus, man and dinosaur coexisting. But wait, theres more!
In 1945 a one Waldemar Julsrud discovered clay figurines buried at the foot of El Toro Mountain on the outskirts of Acambaro, Guanajuato, Mexico. Eventually over 33,000 ceramic figurines were found near El Toro and Chivo Mountain. A lot of the figurines were of dinosaurs, and of course that caused lots of controversy and people thought they were fake, but they were continually tested and finally verified. The reason i mention this find is that many of the sauropods are depicted with spines and/or frills on their backs!
To keep going, the Mokele Mbembe is an african river monster, whose name translates to "one who blocks the flow of rivers". The locals (it is pretty much assumed to be in the congo, but the same tale with different names is repeated much over africa) always describe it as very large, with a long neck and tail, stocky, 3 clawed feet and frills and spines on its back. I thought it rather amazing that all tales i;ve read about with sauropods and man being together, and apparently them still around in africa, have all depicted them looking the same way.
What think you?
(feel free to look stuff up, i would put up a bibliography, but i'm lazy. If you want one ill put one together. Itd be easier to just look up key words on google though if your interested.)
