This database contains information on plant remains identified in frozen megafauna individuals.
We compiled plant records reported from the Pleistocene and early Holocene frozen megaherbivores found in northern Siberia, Alaska and the Yukon Territory. The palaeobotanical data include pollen+spores, macrofossils and DNA analyses reported from gastrointestinal tracts of frozen fauna or coprolites (for more details see Table A2, the manuscript and Supporting information.
Plant nomenclature follows Cherepanov (1995) for vascular plants and Ignatov & Afonina (1992) for bryophytes.
All frozen animal samples are sorted according to their radiocarbon dating, with the same IDs as in the manuscript. Following Ukraintseva (2013) and Willerslev et al. (2014), we used the division of individual samples into periods of pre-LGM (50–25 kyr BP; called Kargin in northern Siberia or Wisconsinian Interstadial in North America), LGM (25–15 kyr BP; Sartan Ice Age/Late Wisconsinian) and post-LGM (15 kyr BP – present; Late glacial and early Holocene).
The taxa of the palaeobotanical records were included in our analyses at three identification levels, as species, genus and family. Higher taxa than families were not considered.
Following tables are included:
Palaebotanical-data-all: this table includes all available palaeobotanical data published. If available, we included also proportional data (percentages) and pollen data from the surrounding sediment, although these were not included in our analyses.
Pollen: Presence/absence data of pollen and spores identified in individual frozen animals. Data used in our analyses.
Macrofossils: Presence/absence data of macrofossils reported from individual frozen animals. Data used in our analyses.
Pollen-Macrofossils-DNA: Presence/absence data based on combined evidence of pollen+spores, DNA and macrofossils. Data used in our analyses.
