Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • It is unclear what role the evolution of land plants and associated changes in terrestrial weathering had on the Sr isotopic composition of the oceans.

    “It is unclear, for example, what role the evolution of land plants and the associated changes in terrestrial weathering had on the Sr isotopic composition of the oceans (Servais et al., 2019), although some authors implicate a clear and direct link (e. g., Lenton et al., 2012).”
  • Including an effect of early plants on silicate weathering with C/P = 1,000 increases organic carbon burial by ∼35%, δ13C by 0.7‰, and O2 by 0.18 PAL.

    “If we include in COPSE an effect of early plants on silicate weathering following ref. 20, assuming C/P = 1,000, this increases organic carbon burial by ∼ 35%, δ 13 C by 0.7 ‰ , and O2 by 0.18 PAL (Fig. 3, magenta).”
  • Early plants selectively increased the flux of phosphorus (relative to alkalinity) weathered from rocks.

    “Furthermore, recent experiments suggest that early plants selectively increased the flux of phosphorus (relative to alkalinity) weathered from rocks.”
  • Extensive shallow water phosphate deposits in the Late Ordovician indicate a marked increase in phosphorus input to the ocean.

    “We also note that extensive shallow water phosphate deposits in the Late Ordovician (35) indicate a marked increase in phosphorus input to the ocean (20).”
  • Earlier plants developed peatlands and had rock-weathering capabilities, so they could also have affected the global carbon cycle.

    “Given that earlier plants developed peatlands (28), and had rock-weathering capabilities (20, 21), they could also have affected the global carbon cycle (18, 20).”

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.
