Archaeocyathids
Explanation:
Phylum ARCHAEOCYATHA

The Archaeocyathids are predominantly an Early Cambrian phylum with no living representatives. They generally have skeletons that formed a porous calcareous cup or cone that resembles later Paleozoic corals. In fact, the archaeocyathids where the reef builders of the Early-Middle Cambrian. The cone-shaped skeletons are commonly constructed of two perforate walls separated by radially arranged vertical blades called septa. As shown in the accompanying figure, the skeletons of archaeocyathids come in two varieties: (i) regulars that have both septa and tabulae but lack dissepiments (small curved plates), and (ii) irregulars that lack septa, but have dissepiments and rod-like bars similar to sponge spicules. This similarity has led some to believe that archaeocyathids belong with the Phylum Porifera. See the diagram below for a representation of an archaeocyathid.
