Keyser Limestone Formation
It turns out the NHSM has several boxes of Keyser Limestone fossils, except that the specific collection locality isn't mentioned, though we can assume that they are from the type-section at Keyser, WV.
For this page, I'm beginning with the ones I collected, followed by the previously boxed specimens. As I go though and clean up these pieces, I'll be adding them to the collection.
