Fossilized sponge.
Despite its importance in sponge biology, however, it has only been possible to reconstruct the aquiferous system in fossil sponges which have close modern relatives as a basis for comparison. Data from exceptionally preserved fossils are required to resolve the evolution of spicules and the aquiferous system.
