This past spring I hunted among the eroded remnants of the Kashong Shale near Greigsville, NY and found a few interesting fossils.
This is a very narrow Crinoid holdfast that must have grown on a jumble of thin shell material.
It is not uncommon to find pieces of shell hash that have flat bryozoans incoporated in with them. This is a piece of matrix that has a Taeniopora exigua piece on one side...
Lastly I found a portion of a crushed Blastoid that may have been a Nucleocrinus or Devonoblastus.
All the above specimens were found in the Kashong shale member of the Moscow formation which is middle Devonian in age (Givetian stage).
