S1: Trace fossilsÂ recorded from the Cleveland Ironstone and Whitby Mudstone formations, Yorkshire, UK. Ichnogenera, max. dimensions of trace, orientation relative to bedding plane, extent of branching, burrow complexity, and detailed features such as burrow linings, spreiten/menisci, bioglyphs; interpretations of feeding, burrow depth, bioirrigation and bioturbatory mode. Possible taxonomic affinity of trace is indicated with supporting information and sources. Abbreviations: V, vertical; H, horizontal; O, Oblique (>10° to bedding). NB Type 1 to 7 are not assigned to ichnogenera by the authors but are distinguished based on their morphometry (see Table 1). Classification scheme for interpretations and rationale can be found in Table 2; Supplementary Table 1 gives quantitative trait classification for each ichnotaxa (for calculations of functional traits). S2: trait classification.
