Pennsylvanian Marine Fossils from Pennsylvania

Recommended Posts

Found these, my first Pennsylvanian Age marine fossils in calcareous shale in a road cut in western Pennsylvania on a recent trip. According to the Fossil Collecting in Pennsylvania guide, the formation is the Ames Limestone. Any help with IDs would be greatly appreciated. Thanks.

Jeffrey, the first 2 pictures seem to me like a mix of gasteropods and/or cephalopods.

pic 3 is a horn coral, but I m not familiar with that location, if it was a european fossil I would have said Caninia sp.

Jeff,

#3 is is a "horn coral"- anthosian rugose coralite. Small curved objects in #2,4 may be Spirorbis (an anelid).

Thanks guys. Pretty sure #2 are small gastropods.

4 and 5 both have Productid brachiopods, the fossil to the left in 4 might be a Pelecypod.

Thanks Howard. I'm pretty sure you're right about the pelecypod. It appears very similar to some Devonian ones I've found.
