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.

While removing out an unknown 2 inch long sponge 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. Thankfully some sort of sudden but gentle event buried the sponge and brachiopods preserving them for me to uncover.
