Hi Evin, I'm curious, is each crab fossil in a concretion? Are they eroded away so that you can see that they all contain crabs? I've come across similar concentrations of concretions in stream beds here in Oregon, (rarely), but most do not contain crabs, but other bits of organic materials, i.e. wood, shell.
