Abstract

We gratefully acknowledge the Comment by Tarhan et al. (2019) in
response to our paper (Liu et al., 2019) discussing preservation of
Ediacara Member fossils. We agree that the mere presence of pyrite or
iron oxides in these rocks does not establish either that pyrite was an
agent of fossilization, or that authigenic marine silica was not. However,
our observations were important in demonstrating both that early
diagenetic pyrite cementation remains a plausible taphonomic mechanism in the Ediacara Member, and that the early silicification taphonomic
model (Tarhan et al., 2016) is undermined by available petrological and geochemical data.
