...), and Margaretia dorus (green alga; Burgess and Wheeler formations). All fossils examined were composed of carbonaceous films, at least in part, but varied with respect to secondary mineral coatings: iron oxides were associated with the surfaces of all three algal species to some degree, and in addition...

..., and macrophytic algae belonging to Margaretia dorus were also analyzed with the microprobe, but none preserved visible Ag. The Ag is not associated with pyrite. The pyrite is mostly euhedral, suggesting it originated in later diagenetic stages ( Fishman et al. 2019 ). Fig. 5. Microprobe energy dispersive...
