The Z-line site, which is named after the coal that sits above it, is very important to our study of Early Paleocene faunas. This is because we know the absolute ages of strata both above and below the horizon in which bone is found. Before we could take any fossils out, however, we had to cut down through a few feet of unproductive rock to get to the productive horizon. Here Don Lofgren and the Peccary Society lend a hand to dig the site out.
