From: Paleoceanography and dinoflagellate cyst stratigraphy across the Lower–Middle Pleistocene Subseries (Calabrian–Chibanian Stage) boundary at the Chiba composite section, Japan

Relative abundance of dinoflagellate cysts and an acritarch from the Chiba and Yoro-Tabuchi sections plotted against the age model of Suganuma et al. (2018, in press). MIS and substage boundary positions are from Haneda et al. (2020b). All taxa are considered to be in situ. The position of Byk-E tephra bed is shown. The local dinoflagellate cyst biozonation (biozones Df1–8) is from the present study. All abundances are expressed as percentages of the total in-situ dinoflagellate cyst counts (or dinoflagellate cyst + N. walldalei counts for the abundances of N. walldalei). See also Fig. 16
