SharkySarah Posted 15 hours ago Share Posted 15 hours ago I was super lucky the other week to be invited to the New Paris Quarry in Bedford co. PA. The owner of the quarry is super nice and knowledgeable. He handed out a geology and ID sheet specific to his quarry. according to that sheet, I spent the day in the Old Port formation. The rock was a very hard limestone. I tried to get some of these brachiopods out of the rock but my rock hammer just dented the rocks. (Keyser fm. Is also present in the quarry along with calcite and fluorite) Here are some calcite pieces: some of the fossils I couldn’t get out: at the end of the day, it was a lot of work for only some reward. Limestone is very hard and the preservation is lack luster. A majority of the finds are brachiopods with the most being Leptaena. Trilobites were super hard to come by, as a group only finding 4 of them. Some of my finds: a worn brachiopod of unknown genus Crinoids my favorite brachiopod rock that sadly isn’t on the ID sheet so I don’t know the name The best find- Symphoria trilobite Leptaena brachiopod this is a weird one. Either coral, mud ripples or something else ? either bryozoan or minerals 3 Link to comment Share on other sites More sharing options...
NickG Posted 14 hours ago Share Posted 14 hours ago Is the contact between the Old Port and Onondaga accessible there? Link to comment Share on other sites More sharing options...

I think in that part of PA the limestone of the Old Port directly underlies the Oriskany Sandstone instead. Link to comment Share on other sites More sharing options...

Do you mean the Ridgeley Member (sandstone) is exposed there? My understanding is where the Ridgeley Member isn't present, that the Shriver Chert is instead. Is this reflective of what you mean? The matrix and some of the fauna definitely looks similar to what I've seen in the New Creek Limestone in the type section. I'm not 100% familiar with the Old Port vs its southern lateral equivalents in western MD/WV/VA. #22 looks like messed up sponges. I've seen similar preservation in the New Creek Limestone at the type section. #24 resembles Strophodonta. Get these papers tho: Bowen, 1966, Brachiopods and stratigraphy of the Elbow Ridge Sandstone (Lower Devonian) of Pennsylvanian, Maryland, and West Virginia: Journal of Paleontology 40, 1051--1062. Bowen, 1967, Brachiopoda of the Keyser Limestone (Silurian-Devonian) of Maryland and adjacent areas. Geological Society of America Memoir 102.
