The biota of the Burgess Shale appears to be typical of middle Cambrian deposits. Although the hard-part bearing organisms make up as little as 14% of the community, these same organisms are found in similar proportions in other Cambrian localities. This means that there is no reason to assume that the organisms without hard parts are exceptional in any way; many appear in other lagerstätten of different age and locations.
