From the middle -upper Silurian ,Wenlock series.
Collected from Much Wenlock ,Shropshire.
I purchased this as part of an old time collection ,its sad when our older collectors pass on, but the only way most of us will be able to own any of these specimens,
Very difficult to obtain of this Quality ,this particular specimen was part of the Snell collection,that i purchased from the Hampshire Mineral and fossil show.
The specimen has been air abraded to a high standard at our workshop and measures 69mm x 53mm.
