Consider these astonishing finds : Over the last few decades, miners in South Africa have been digging up mysterious metal spheres ( aka Klerksdorp spheres).Origin unknown, these spheres measure approximately an inch or so in diameter, and some are etched with three parallel grooves running around the equator.The most astonishing etchings, however, clearly represent dinosaurs – brontosaurs, triceratops (see photo), stegosaurus and pterosaurs.
Further investigation revealed that the porcelain was surround by a hexagonal casing, and an x-ray revealed a tiny spring at one end.
What appears to be a fossilized human finger found in the Canadian Arctic also dates back 100 to 110 million years ago.
And what appears to be the fossil of a human footprint, possibly wearing a sandal, was found near Delta, Utah in a shale deposit estimated to be 300 million to 600 million years old.
A nail was found embedded in a sandstone block from the Mesozoic Era. The Dropa stones, otherwise known as the Dzopa stones, Dropas stones or Drop-ka stones, are said by some ufologists and pseudoarchaeologists to be a series of at least 716 circular stone discs, dating back 12,000 years, on which tiny hieroglyph-like markings may be found.
Each disc is claimed to measure up to 1 foot (30 cm) in diameter and carry two grooves, originating from a hole in their center, in the form of a double spiral.
