Mammoth meteorite from 50 million years ago found buried near Stockton, California. Another one found earlier near by

Its an egg.

If you look at Google Earth, especially in the sparsley populated areas around Africa and Australia, I have noticed MANY impact craters with rocks still visible. I would be surprised if someone is not already using this to find them.

I think it was before 50 million years, maybe 26,000, or 10,500 years ago.

I do that where I live in Minnesota. Carefully check out the satellite maps, which are readily available online, to see if there are any evident impact structures near you. If it looks like it, go check it out. Remember that the whole idea of rocks from space is only about 200 years old. There hasn't been all that much investigating done. And sat maps online is a huge resource. Earth has been pummeled just as much as the Moon and Mars, but the craters have been covered up by weather, erosion, and natural processes. The craters are out there, under your feet, they just need to be found.

On this Victoria Lake impact structure from the link, which is 10 miles west of Stockton, California, here is the Google satellite map-

While the 3 mile wide crater is not immediately evident. If you look closely at the areas without housing or development, there does appear to be some secondary impact structures in the area.

But there have been some of these million year old meteorites discovered before. Usually Iron meteorites, usually in rusty deteriorated condition. Theres a few of them in Australia and South America. But a million year old meteorite isn't nearly as cool as one that fell recently. Like 1969 in Allende or Sikohte-Alin in the 1940's. Good find though, if you go dig one up, it's gonna be worth more than the average rock!
