Why are most fossils of cnidarians Coral fossils would you expect to find a fossil sponge?

Marine depositional environments are more plentiful, and the hard shells and body parts of many marine organisms do not decay from bacteria, or are not easily destroyed by predation. Additionally, the organism's remains are much more likely to be covered from precipitating sediments settling out of the water.

∙ 12y agoFor an organism to fossilize and be preserved is a rare thing. As most cnidarians have soft bodies it would be even rarer to fossilize. Mainly those who excrete a form of skeleton, such as corals, are normally preserved and these are relatively common.

How are cnidarians more advanced then jellyfish?
Sponges are less complex because they are just made of individual cells. There is no level of organization past cells in sponges. Cnidarians, on the other hand, have tissues, a higher level of organization. Tissues allow for some forms, like box jelly fish, to have eyes (this is just one of many advantages of tissues). Cnidarians' level of organization stops there though, they have no organs (heart, brain, etc.).
What hexactinellida can be found in the Cambrian?
Fossil evidence for the Hexactinellid class of sponge actually predates the Cambrian Period. Fossils of the genus Paleophragmodictya is the oldest fossil sponge currently known and was found in rocks dating back to the Ediacaran Period of the Neoproterozoic Era.It is thought that the Extinction events that occured in the early Cambrian effected the early sponges greatly but diversification of Haexactinellida after this brought many new forms. A species of Konyrium has been found in late Cambrian rocks.Many species were to evolve though out the Paleozoic and Mesozoic Era although hexactinellida would not see maximum diversity until the Cretaceous Period.
