 First few feet down, you can find fossils. After the first few feet, that's about 20,000 years, there are no fossils until you get way down here. That's about the same as late Carboniferous on Earth. Then you get the fossils again. It doesn't figure. Isn't that usual? Changes in geological eras? You don't get it, man. I'm not talking about eras. I'm talking about years.
