Newbie exploration of Pennsylvania and surrounding states
Shale_stack posted a topic in Fossil Hunting Trips
Super new to the world of fossils with no formal education. Currently looking for locations near Berks county Pennsylvania or within 2-3 hours. Up to 6 is okay too but it’s a bit far. Feel free to PM me. I’m feeling frustrated not knowing much. -

The Delaware Bay and Delaware River shores are littered with lovely marine erratics. They aren't local. They aren't young. You have to dig pretty darn deep in Delaware just to get to the Cretaceous in some places. These are Paleozoic. Many pieces are limestone and probably from the Mahantango FM. But, I find just as many that are definitely not limestone. They are silicified to cert and other shades of SiO2 plus a bit of dark blue/black mineral. I'm thjingking they are ordovician, based on the Foerstiphyllum sp. corals here. The puzzle is, where do they and the other silicified corals, sponges, bryozoa etc, come from? The DE geological Survey doesn't even mention the erratics. I was told that it's been washed down from the Appalachians. Okay, there are definitely ordovician layers there that could have eroded into the river, but all I can find are formations of limestone and fine-to-very-fine grained sandstone. Been doing all kinds of searching through descriptions of geological formations in the area and I'm coming up blank. Anyone have any ideas?
