SUPPLEMENTARY MATERIAL DR2015170

Figure S1. Palaeogeographic reconstruction of west-central North America at the time of the K-

Pg boundary event. Areas of active sediment accumulation (basins) were bounded by positive

tectonic features extant at the time of the K-Pg boundary event: the Sevier deformation front to

the west, Laramide uplifts Montana southwards, and the flexural forebulge to the east

(references for the ages of major tectonic structures are superscripted following their

abbreviated names). Catuneanu and Sweet’s (1999) forebulge in Saskatchewan/Manitoba is

projected southward into North Dakota based on evidence for eastward thinning of the Upper

Maastrichtian Hell Creek Formation towards central North Dakota (Johnson et al., 2002) and

chron 29r containing the K-Pg boundary (Lerbekmo and Coulter, 1984; Hicks et al. 2002; Lund

et al. 2002), and the absence of evidence for complete K-Pg boundaries towards that same

direction (Murphy et al., 1995). South of this, where Maastrichtian/Danian rocks are absent, the

position of the forebulge is conjecture. Active sediment accumulation between positive tectonic

features is confirmed locally by the preservation of either an Ir anomaly, shocked minerals a

readily identifiable boundary claystone layer or a fern-spike (references to work describing

localities which fulfil this criteria are superscripted following their abbreviated names). Areas of

active sediment accumulation at the time of the K-Pg boundary in terrestrial rocks of North

America are suggested more generally by the occurrence of magnetostratigraphic subchron

C29r (D’Hont et al., 1996; Gradstein et al., 2012) and/or the occurrence of typical palynomorph

taxa of the latest Maastrichtian followed by those of the earliest Danian (e.g. reduction on

Triprojectoate group diversity followed by diversification of the Juglandacaea family;

Leffingwell, 1970; Tschudy and Tschudy, 1986; Sweet and Braman, 2001), indicating no major

or regional unconformity occurs at this time (references for the ages of the lithostratigraphic

unit or units which thus bracket the K-Pg boundary event are superscripted following their

abbreviated names). Areas of interpreted sediment accumulation on the map have been

populated with palaeoenvironmental interpretations of sedimentary facies adjacently

underlying the K-Pg boundary interval (reference for palaeoenvironmental interpretations of

facies are subscripted after the abbreviated name of the lithostratigraphic units) and

palaeoflow data from the upper Maastrichtian and lower Danian (reference to palaeoflow

measurement next to arrow).

Table S1. Results of the petrological analyses of 184 coal seam samples and δ13C analyses

carried out on 319 subsamples collected from eight localities in Alberta and Saskatchewan. See

Figure 1 and Table 2 for sampling location data.

Table S2. Correlation matrix of standard Pearson’s product-moment correlation coefficient for

individual macerals and maceral groups for all 184 petrological analyses, and δ13C

measurements of 319 subsamples. Samples for which no petrological results were determined

are omitted.
