    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.

    Wow, that’s a beauty!  Still on my “to do” list to collect some silicified material such as this and try acid prepping. Thanks for posting.
