This is an excellent fossil sponge. It is a Diagonella sp. from the Wheeler Formation of Utah. This type of sponge has also been found in the famous Burgess Shale deposits. Sponges are fairly uncommon in the fossil record. Cambrian sponges apparently had skeletal nets that were weakly united and generally required quiet water for preservation. This urn-shaped sponge has great form and exhibits wonderful detail. Under magnification, even the spicules of the sponge can be seen. The fossil has nice color and contrast and is well presented on the natural plate of shale. This is a textbook specimen of an unusual organism from the Middle Cambrian sea.
