Rock Fragment Found in Field Turns Out to Be Ancient 4.6-Billion-Year-Old Meteorite

It has been estimated that there is at least one recoverable meteorite for every square kilometer of the earth's surface.

The trick is finding it, lol. I have collected a few specimens during my life, will post some pics when I'm home from work.

Most meteorites date to the early days of the solar system, between 4 and 5 billion years ago.
