Here is a closer view of the Cadell Formation. About 90 percent of all fossils at the site are a single species of turritellid gastropod, but the other ten percent is fantastically diverse. I've counted over 200 mollusc species from here, and there are crustaceans, corals, bryozoans, brachiopods, echinoids, sharks teeth and the the occasional whale bone as well.
