Here is an unusual fossil invertebrate. This is a large example of Chancelloria pentacta from Utah. This type of animal is sort of an enigma, and has been found in the Burgess Shale fauna. It was first thought to be a "glass sponge", but it has now been described as a "coeloscleritophoran". This fossil has excellent form and exhibits great detail - the star-shaped sclerites are easily seen under magnification. The tapering, cylindrical form of the animal is wonderfully displayed. The red-orange coloration is beautiful and fully natural. The fossil is well positioned on the natural plate of shale. This is an excellent specimen of this odd Cambrian animal. And, to top it off, there is an unusual juvenile carpoid, Castericystis vali, attached to the base of the Chancelloria.
