For the Pleistocene, additional fossil occurrences dated to five temperate stages and interglacial periods were included; Holocene occurrences were obtained from the World Checklist of Vascular Plants. The final fossil dataset comprised 711 occurrences from PBDB and literature.",

  "searched": "Read the primary Nature Communications article and its figure/methods text. Checked the stated 711-occurrence count for omitted time range, geographic scope, population/taxonomic unit, source coverage, and sampling/binning limits. The passage specifies 66 Ma to present, 11 named Western/Central European countries, tree genera, and combined PBDB/literature provenance; it also specifies special Pleistocene stage/interglacial bins and Holocene WCVP sourcing."
