Little did they guess that this poorly preserved fossil should herald the discovery of another exceptionally preserved passet. This was in large part owed to a few controversy provoking studies of some of its most sirius fossils in the light of major upheavals in our understanding of animal relationships. Ultimately, Sirius Passet was eclipsed by the seemingly incessant stream of new sensational discoveries from the Burgess Shale and Chengjiang.

The Sirius Passet Lagerstätte of North Greenland contains the first exceptionally preserved mat-ground community of the Cambrian, dominated, in terms of abundance, by trilobites but particularly characterized by iconic arthropods and lobopods, some also occurring in the Burgess shale.

Results show that the guts contain a high concentration of calcium phosphate approximating to the mineral francolite , whereas the adjacent muscles are silicified. This indicates a unique, tissue-specific taphonomy for this Cambrian taxon.
