Daddy found these interesting things on a hill that was cut a little to widen the road. At first we thought they might be some kind of fossil, but when I looked them up I found out they were concretions.

They're so cool, and I had never heard of them before. (Incidentally, the picture is from a site with information about fake dinosaur egg fossils...it was really cool, too...with links to real dinosaur eggs and pics of fakes and why they were silly fakes~also info about concretions and geodes because people will think they're dino eggs...really interesting stuff...)
