While removing an unknown sponge by acid dissolution from the Permian Fort Apache Member of the Schnebly Hill Formation from northern Gila County in Arizona I found several silicified brachiopods with spines.
Several Bellaclathrus spinosus brachiopods were present ranging from 0.75 to 1.5 inch across and had spines as long as 1 inch.
The pedicle valve of the brachiopod in the first and second photos is about 1 inch wide not including spines. This is the finest specimen with spines that I have found.
The third photo shows the brachiopod attached to several others of the same species.
Fourth and fifth photos are from Winters 1963 reference below.
