The “real work” of the beginning of the Cambrian Explosion may in actuality be as short as a two to three million year time frame (Hugh Ross, Jonathan Wells) which is well within what is termed the "geologic resolution time" i.e. The time frame for the main part of the Cambrian Explosion apparently can't be shortened any further due to limitations of our accurately dating this ancient time period more precisely.
"The Cambrian Explosion was so short that it is below the resolution of the fossil record. It could have happened overnight. So we don't know the duration of the Cambrian Explosion. We just know that it was very, very, fast."

The scant "track" evidence for worms in the pre-Cambrian has now been brought into question:
Discovery Of Giant Roaming Deep Sea Protist Provides New Perspective On Animal Evolution:
Excerpt: This is the first time a single-celled organism has been shown to make such animal-like traces. The finding is significant, because similar fossil grooves and furrows found from the Precambrian era, as early as 1.8 billion years ago, have always been attributed to early evolving multicellular animals. "If our giant protists were alive 600 million years ago and the track was fossilized, a paleontologist unearthing it today would without a shade of doubt attribute it to a kind of large, multicellular, bilaterally symmetrical animal," says Matz, an assistant professor of integrative biology. "We now have to rethink the fossil record."
Interestingly, "simple" Jellyfish and Sponges appeared suddenly in the fossil record a few ten million years before the Cambrian Explosion, and have remained virtually unchanged since they first appeared in the fossil record. Moreover, contrary to evolutionary thinking, Jellyfish and Sponges appear to have essential purpose in preparing the ecosystem for the Cambrian Explosion that was to follow.
Marine animals cause a stir - July 2009
Excerpt: Kakani Katija and John Dabiri used field measurements of jellyfish swimming in a remote island lake, combined with a new theoretical model, to demonstrate that the contribution of living organisms to ocean mixing via this mechanism is substantial — of the same order of magnitude as winds and tides. (Winds and tides, due to their prevention of stagnation, are known to be essential for life on earth.)
Sponges Determine Coral Reef's Nutrient Cycle
Excerpt: Sponges, which have worldwide distribution in the oceans, filter water. They take up planktonic particles such as bacteria and excrete inorganic nutrients. In turn, these nutrients can facilitate the growth of marine plants and other organisms. Sponges filter water at a phenomenal rate: if the seawater were to remain stationary, the sponges would have completely pumped it away within five minutes,,,, these organisms play a key role in the marine nutrient cycle due to their incredible capacity to convert enormous quantities of organic plankton into inorganic material (nutrients). http://www.sciencedaily.com/releases/2005/09/050917085649.htm
Fossils of all types of sponges alive today have been found virtually unchanged in rocks dated from 580 to 523 million years ago. Sponges with photosynthesizing endosymbionts produce up to three times more oxygen than they consume, as well as more organic matter than they consume. (Wikipedia)

My guess is that, as with photosynthetic bacteria, sulfate reducing bacteria, sponges, and jellyfish, Ediacara biota will ultimately be found to have a essential biogeochemical role in preparing the earth for more advanced life to appear in the Cambrian explosion.
