I found this somewhere near Hancock, MD I think. It was many moons ago, before I knew much about fossils so I don't remember where I found it exactly. It's limestone and I noticed some strange looking things, possibly fossils. Tell me what you guys think, I'd guess Ordovician simply because it seems to contain limestone in that area.

I was splitting some rocks from a visit to a fossils sit in Maryland a while back, mahantango formation. I split one open and I got a positive and negative of a larger brachiopod (relative the the usual shoals of 1 cm shells) about an inch by an inch and a half (approx). Last pic is negative, rest are positive.I was guessing strophomena? Is it possible to get down to the species level? Any papers on this part of the mahantango would help (info is scarce for most Maryland sites pretertiary).

From the album: WhodamanHD's Fossil collection.
Large burrow, most likely polychaete worm. Collected outside McCoys ferry. Other than that not much, a few shells. The obverse is below. -
From the album: WhodamanHD's Fossil collection.
A hash of many species of brachiopods and crinoid s, no idea what most are. Found outside of McCoys ferry. On the back is a worm burrow, probably polychaete, and another possible one shaped like a chicken footprint, even after an ID thread we couldn't come up with a better explanation. Back is pictured below. -
So as I am new to this whole formation and it's species, so I need some help again. Does any one know the species or genus? This is a brachiopod, the largest species I have yet come across in the Mahantango outcrop outside of McCoys ferry. I have found a few of these, only one larger than this but unfortunately it was broken. In big pool, MD I once came across a rock face with around 10 eroding out of the cliff, I didn't have the tools to collect them however. I can try to provide any other useful information needed to ID.
