Faunas
The mode of preservation preserves a number of different faunas; most famously, the Cambrian "Burgess Shale type faunas" of the Burgess Shale itself, Chengjiang, Sirius Passet and Wheeler Formation. However, different assemblages are also preserved, such as the microfossils of Riphean (Tonian-Cryogenian age) lagerstätten.
