Why are dinosaur fossils hard to find in in North Carolina?

We do get a number of dinosaur bones … a fair number – 40 to 60 dinosaur bones, decent bones. If you take that in the amount of area that we actually have exposed, which is very, very small … (and compare it to) out west where they’ve got thousands of square miles, yes, they get a lot more bones. But we have very little exposure here. If you look at the map of Eastern North Carolina and look at the Cretaceous deposits, they’re covering several counties – but it’s all tree-covered. So there’s no erosion going on except on rivers and streams and a few places where man has dug into the ground for a quarry or a farm pond or something.
