“…In addition, and despite sharing a common pathway of preservation (Gaines et al 2012a), variations in preservation of anatomical aspects within and among species and different Burgess Shale-type fossil assemblages are still poorly understood, in particular in the vicinity of the Burgess Shale itself. In the Burgess Shale Formation, soft-bodied fossils occur in more than a dozen stratigraphically related localities above and along the Cathedral Escarpment, from Fossil Ridge to the Monarch, 60 km to the southeast (Collins et al 1983;Johnston et al 2009;Caron et al 2010Caron et al , 2014, offering a rare opportunity for comparative taphonomic and paleoecological study at a regional scale. Unfortunately, most of these sites are difficult to access, are still poorly known, and few have been sufficiently sampled to warrant more detailed quantitative comparisons.…”

“…As in Cambrian Burgess Shale-type biotas (Caron & Jackson 2008;Caron et al 2014;Zhao et al 2014), species diversity and abundance in the EBS are dominated by panarthropods, which comprise 28 recorded species to date, with several yet to be described. The survey of the biota below is accordingly focused on arthropods, with taxonomic groups drawing on the classification of Legg et al (2013).…”

Recent fossil discoveries from the lower Cambrian Emu Bay Shale (EBS) on Kangaroo Island, South Australia, have provided critical insights into the tempo of the Cambrian explosion of animals, such as the origin and seemingly rapid evolution of arthropod compound eyes, as well as extending the geographical ranges of several groups to the East Gondwanan margin, supporting close faunal affinities with South China. The EBS also holds great potential for broadening knowledge on taphonomic pathways involved in the exceptional preservation of fossils in Cambrian Konservat-Lagerstätten. EBS fossils display a range of taphonomic modes for a variety of soft tissues, especially phosphatization and pyritization, in some cases recording a level of anatomical detail that is absent from most Cambrian Konservat-Lagerstätten.

“…[4,5] Other examples of exceptionally preserved biotas include the plants and animals found in the Carboniferous Mazon Creek concretions of Illinois ( Figure 3D), [6] the fishes that preserve phosphatized subcellular details of muscle tissue in the Cretaceous Santana Formation concretions from Brazil, [7] and the feathered dinosaurs that reveal evidence of plumage color and flight capability from the Cretaceous Jehol sequences of north-eastern China (Figure 2A). [8] Despite the diversity of settings that yield exceptionally preserved fossils, many Konservat-Lagerstaẗten share biological and geological processes such as rapid burial, limited or no bioturbation, decay suppression through anoxia or euxinia, and sealing of sedimentary laminae by microbial mats and early diagenetic cements (Figure 1).…”

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that remove or preserve morphological information. Investigations of fossils preserving nonbiomineralized tissues suggest that certain structures that are decay resistant (e.g., the notochord) are rarely preserved (even where carbonaceous components survive), and decay-prone structures (e.g., nervous systems) can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils.
