Powell and MacGregor, 2011 Appendix S1. Species trait data used in this study. See text for sources. VARIABLE DESCRIPTION species species binomial global_fate6665 global stratigraphic range categorized using the 66-65 Ma interval. V = victim, S = survivor, P = extinct prior to the K/Pg boundary globalfate_6663 global stratigraphic range categorized using the 66-63 Ma interval lat_max_dd maximum latitude at which the species was sampled, in decimal degrees lat_min_dd minimum latitude at which the species was sampled, in decimal degrees lon_max_dd maximum longitude at which the species was sampled, in decimal degrees (positive values are east) lon_min_dd minimum longitude at which the species was sampled, in decimal degrees (positive values are east) lat_range latitudinal range, in degrees max_great_circle_km maximum great circle distance, in kilometers LAD_neptune global last appearance datum from Neptune database, in Ma FAD_neptune global first appearance datum from Neptune database, in Ma modal_abund_beforeXT modal abundance before K/Pg mass extinction, from raw core data modal_abund_afterXT modal abundance after K/Pg mass extinction, from raw core data *The remainder of the variables were downloaded directly from the Mesozoic Planktonic Foraminiferal Taxonomic Dictionary (Mesozoic Planktonic Foraminiferal Working Group 2006), www.chronos.org. Appendix S2. Core data used in this study. See text for sources. The following variables are provided for each K/T boundary definition and each core: VARIABLE DESCRIPTION species species binomial FAD_mbsf first appearance of the species in the core (meters below sea floor) LAD_mbsf last appearance of the species in the core (meters below sea floor) rangeCI_m stratigraphic range extension (meters), based on Marshall 1994 boundary_mbsf Cretaceous/Paleogene boundary in the core (meters below sea floor) globalLAD_Ma global last appearance (millions of years ago) category_global “EARLY” if species disappeared globally prior the K/T boundary (these species were removed from analyses); “EXT” if species became globally extinct at the K/T boundary; “SURV” if species survived past the K/T boundary. The K/T boundary was defined as either 66-65 Ma or 66-63 Ma; see text for details. category_local_raw for surviving species, “THRU” if a species’ raw stratigraphic range within a core extended past ‘boundary_mbsf’; ‘EXTIRP’ otherwise. category_local_Marshall for surviving species, “THRU” if a species’ extended stratigraphic range within a core extended past ‘boundary_mbsf’; “EXTIRP’ otherwise.
