Petaloptyon danei is a goblet-shaped hexactinellid sponge known from rare fragments from the Middle Cambrian Burgess Shale. A few specimens of Petaloptyon are known from the Greater Phyllopod bed, where they comprise under 0.01% of the community.[1]

The fragments show the living animal had a stalk, and had panels with a lattice pattern.
