Has anyone Really looked at the Petroglyphs at the Bottom Right in the Picture? I enlarged this picture, and it shows what appears to be a u.f.o. with landing gear.
There appear to be 2 objects with landing gear one circular and the other a long horizontal shape![/quote]
Those are probably turtles.[/quote]

<<A winter night above the prehistoric site of Teimareh in central Iran. There are over 20,000 engraved images in the valley which put the region among the world's most populated petroglyph sites, still largely undiscovered. In this view a unique panel of over 150 pictures is remotely located in the Zagros mountains. There are signs of the first era of horse riding in the Middle East (~ 6000 years ago) and some other pictures are from late Paleolithic (12000 years ago). But few of them might be even surprisingly older. They show animals which became extinct in this region by the ice age, including Smilodon (saber-toothed tiger) and a kind of large armadillos known as Glyptodon.>>[/quote]

[float=right][img3="[b][color=#0000FF]Glyptodon measured over 3.3 m in length and weighted up to 2 tons. It was covered by a protective shell composed of more than 1,000 2.5 cm-thick bony plates, called osteoderms or scutes. Each species of glyptodont had its own unique osteoderm pattern and shell type. With this protection they were armored like turtles. Unlike most turtles, glyptodonts could not withdraw their heads, but instead had a bony cap on the top of their skull. Even the tail of Glyptodon had a ring of bones for protection. Such a massive shell needed considerable support, evidenced by features such as fused vertebrae, short but massive limbs, and a broad shoulder girdle.[/color][/b]"]http://upload.wikimedia.org/wikipedia/commons/thumb/0/09/Glyptodon_%28Riha2000%29.jpg/626px-Glyptodon_%28Riha2000%29.jpg[/img3][/float]
<<Glyptodon (Greek for "grooved or carved tooth") was a large, armored mammal of the family Glyptodontidae, a relative of armadillos that lived during the Pleistocene epoch. It was roughly the same size and weight as a Volkswagen Beetle, though flatter in shape. With its rounded, bony shell and squat limbs, it superficially resembled turtles, and the much earlier dinosaurian ankylosaur, as an example of the convergent evolution of unrelated lineages into similar forms. Glyptodon is believed to have been an herbivore, grazing on grasses and other plants found near rivers and small bodies of water.
Glyptodon is part of the superorder of placental mammals known as Xenarthra. This clade of mammals also includes anteaters, tree sloths, armadillos, and extinct ground sloths and pampatheres. Glyptodon originated in South America. A related genus, Glyptotherium, reached the southern region of the modern USA about 2.5 million years ago as a result of the Great American Interchange, a set of migrations that occurred after North and South America were connected by the rising of the volcanic Isthmus of Panama. They became extinct about 10,000 years ago. The native human population in their range is believed to have hunted them and used the shells of dead animals as shelters in inclement weather.
The nasal passage was reduced with heavy muscle attachments for some unknown purpose. Some have speculated that the muscle attachments were for a proboscis, or trunk, much like that of a tapir or elephant. Most animals with a trunk, however, have nasal bones receding back on the skull, and glyptodonts do not have this feature. The lower jaws were very deep and helped support massive chewing muscles to help chew the coarse fibrous plants that can be found along river and lake banks.>>[/quote]
