    This is a Late Devonian sponge collected from the Percha Formation found at the type locality on Brandenburg Mountain in Pinal County, Arizona. This sponge, although missing most of its stem, has the largest complete head reported.
     
    First photo is a close up of the star shaped spicules that average 1 mm across.
     
    Second photo is of the top of sponge that is 60-64 mm across by 20 mm thick. Zoom in the see numerous  star shaped spicules. You can also see rod like sponge structures that look like villi when viewed from the top.

    Beautiful, I love these. :wub: The latest Treatise has this classification for Astraeospongiidae: 

    class Hetaractinida

    order Octactinellida

    family Astraeospongiidae

     

    (I've been looking up my Carboniferous heteractinids. :) )

    NICE!

    The bibliography in Rigby's piece mentions

    ---Reitschel, S. 1968. Die Octactinellida und ihnen
    verwandte palaozoische Kalkschwamme (Porifera,
    Calcarea). Palaont. Zeit. 42:13-32.---

    That should read "Rietschel",of course

    Also,a deep nod of gratitude for the thesis link
