“Evidently supporting the cephalate model are the fishlike, fossil yunnanozoans, from the Yunnan Province of China, of which Haikouella lanceolatum (Figure 5B) is known in the most detail (Chen et al., 1999; Chen and Li, 2000; Mallatt and Chen, 2003; Mallatt et al., 2003).”

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.
