It looks like they have found nematode fossils in the same area that 
they are finding ediacaran fossils.  They think the fossils are in 
sediments 15 million years older than the Cambrian explosion 
diversification.

They think that they represent early members of ecdysozoans.  Nematodes 
are protostomes, but are more closely related to arthropods than other 
protostomes.  This would mean that animals like the phylum mollusca 
existed or at least branched off as multicellular animals long before 
their appearance and diversification during the Cambrian explosion.
