Here is a nice plate of unusual Cambrian fossils. This is a rare multiple slab of Chancelloria pentacta from the Wheeler Formation of 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''. There are two distinct examples of this strange fossil on the plate. Both of the fossils have great form and exhibit fine detail - the star-shaped sclerites are very easily seen. The yellow-orange color of the fossils is totally natural, which contrasts beautifully with the grey matrix. This is a very displayable specimen of this puzzling Middle Cambrian animal.
