Cryptolithus sp. (cephalon)
Upper Ordovician
Martinsburg Shale
Route 44/55 Roadcut (Town of Gardiner)
Ulster CO., NY
The Martinsburg Shale is generally poorly fossiliferous in this area, but I found a thin layer that was rich in Cryptolithus trilobite cephalon pieces, crinoid stem pieces, and occasional brachiopod and cephalopod pieces. See last photo for the rest of the story.
