Abstract:
This thesis describes and elucidates the taphonomic pathways responsible for the exceptional preservation of some of the most common elements of the Sirius Passet Lagerst├Ątte (early Cambrian), North Greenland. Investigative techniques including cathodoluminescence, are tested first on silicified molluscs from the Oligocene of Antigua, associated with a volcanic source; described in chapter 2. By describing the depositional environment of the Sirius Passet biota in detail and using a combination of analytical techniques such as SEM, EDAX, SEM-CL and elemental mapping two published papers address a number of the key research questions surrounding the unique taphonomic pathways in the Sirius Passet biota and their broader significance in understanding Cambrian ecosystems. The papers are included in the form of chapters 3 and 4 and the published versions included in the appendices. A unique, mat-dominated, tissue specific taphonomic pathway is proposed, more akin to the Proterozoic than the typical Burgess Shale Type (BST) preservation seen elsewhere in the Cambrian. This together with mouldic preservation indicates a range of taphonomic styles concomitant with the range of new biotas at the dawn of the Cambrian Explosion.
