A long-term record of early to mid-Paleozoic marine redox change
Open accessAbstract
Early Paleozoic bottom waters were mainly ferruginous, like the Neoproterozoic, with a shift to increased euxinia in the Devonian.

There was a shift in samples deposited under anoxic bottom waters from being dominated by ferruginous conditions to being dominated by euxinic conditions.
“There also appear to be changes in samples deposited under anoxic bottom waters, with a shift from samples being dominated by ferruginous conditions to being dominated by euxinic conditions (Sperling et al. 2021).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
