Seven Most Mysterious Archaeological Finds on Earth

From the July 22, 2010, Love Science by Heather Whipps.

I'm just listing. The site has pictures and more information:

1. Atlantis

2. Stonehenge

3. Ancient Animal Traps? in Israel, Egypt and Jordan

4. ANTIKYTHERA MECHANISM-- Found on a sunken Greek cargo ship believed to be at least 2,000 years old with a maze of interlocking gears and mysterious etched characters.

5. Nazca Lines

6. Great Pyramids

7. GOBEKLI TEPE-- Turkey, considered to be the oldest place of worship.

I'd never heard of 3. 4 or 7. I've seen 2 and 6 thanks to Mom.
