Penn dixie is an interesting site for fossil collecting. Most of the fossils are in the North end of the quarry. Under a layer of gravel are the shale layers. Each layer has different fossils. I’m still clumsy enough at collecting that I can’t easily identify the layer I’m prying up.
I only searched for an hour or so, but I found a couple new fossils. Penn Dixie charges $6 for access to the site, and lets you take home anything you find. I saw more than one fellow hauling out a head sized rock. I didn’t bring a bag to carry my loot, so I was restricted to what would fit into the back pocket of my camera bag.
