    Iron is an amazing substance when it comes to color, and there's a lot of it in the matrix at this site.

    Ah that's great. If there is a lot of iron, are there then also a lot of pyrite fossils there too? I would think so, but maybe there aren't any sulphides there... (Pyrite = iron sulphide)
