Choia Sponge FossilDescription: Lower Cambrian Pioche Shale fossils, and especially soft-bodied organisms of this level of preservation have become exceptionally difficult to obtain in the last few years.

Choia have a circular center from which the arms radiate. This one has a rust/orange color which contrast well against the gray/green matrix.
