If one dream should fall and break into a thousand pieces, never be afraid to pick one of those pieces up and begin again.

It's really interesting how a tiny little shell from a sea creature living millions of years ago can tell us so much about past ocean conditions. We can tell approximately what the temperature was at the bottom of the ocean. We also have an approximate measure of the nutrient content of the water the creature lived in. And, when we have information from several locations, we can tell the direction of ocean currents.
