“The cold trap, however, might not have existed continuously during the Archean eon due to fluctuations to very low total atmospheric surface pressures (Som et al. 2016; Lammer et al. 2018; St¨ ueken et al. 2020.”

“Third, vesicle volumes in 2.7-Ga-old basaltic lava flows erupted at sea level imply a 0.23 ± 0.23–bar [2σ] paleopressure (56).”
From The Archean atmosphere (2020) · cites this paper as [56]
In the citing paper
“Marine phyllosilicates at 3.8 Ga ago are ammonium enriched (146, 147), which probably came from porewater ammonium (NH4+) derived from degraded organics (Table 1) (148, 149), and these data have been used to argue that Archean N2 was sequestered into solid phases after an early advent of biological nitrogen fixation (56, 150).”
From The Archean atmosphere (2020) · cites this paper as [56]
In the citing paper
“N 2 likely has been outgassed and built up during the Archean eon (Mikhail and Sverjensky 2014; Som et al. 2016; Lammer et al. 2018; Lammer et al. 2019; St¨ ueken et al. 2020; Sproß et al. 2021), and became the main atmospheric species besides CO 2 .”

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.
