Introduction

This file contains supplementary material describing groupings of dinoflagellate cyst taxa, and one table containing the taxonomic citation of dinoflagellate cysts identified in this study and their thecate equivalents.

       Cysts of Polykrikos kofoidii and Polykrikos schwartzii follow the nomenclature of Matsuoka et al., [2009]. All dinoflagellate cysts were identified to the species level where possible, however due to morphological similarities and unfavourable orientation it was not always possible, and some cyst taxa are grouped together. Brigantedinium spp. consists of Brigantedinium cariacoense, Brigantedinium simplex, and other round brown cysts, as archeopyles were not always observed due to unfavourable orientations or folding. Selenopemphix quanta and cyst of Protoperidinium nudum are grouped together as these two cyst species show a high degree of morphological similarity. Cyst type A has been previously identified by studies in the Northeast Pacific [e.g. Radi et al., 2007; Limoges et al., 2010]. Other spiny brown cysts of unknown affinity were placed in the spiny brown (SBC) category.
