Unscramble the Blue Letters
When we find a fossil, we mark it. Today, we've got great technology: we have GPS. We mark it with a GPS fix, and we also take a digital photograph of the specimen, so we could essentially put it back on the surface, exactly where we found it. And we can bring all this information into big GIS pagakecs, today. When we then find something very iantrpomt, like the bones of a huamn ancestor, we begin to excavate it eemlrexty cllruaefy and slowly, using dental picks and fine paintbrushes. And all the sediment is then put through these snrcees, and where we go again through it very carefully, looking for small bone fragments, and it's then washed.

When we find a fossil, we mark it. Today, we've got great technology: we have GPS. We mark it with a GPS fix, and we also take a digital photograph of the specimen, so we could essentially put it back on the surface, exactly where we found it. And we can bring all this information into big GIS packages, today. When we then find something very important, like the bones of a human ancestor, we begin to excavate it extremely carefully and slowly, using dental picks and fine paintbrushes. And all the sediment is then put through these screens, and where we go again through it very carefully, looking for small bone fragments, and it's then washed.
