►Revisitation of Schopf (1947) ground-breaking examination of maceral relationships. ►Use of modern reflected light nomenclature for thin sections. ►Huminite-funginite relationships explored. ►Oxic, attrinite-rich intervals are also rich in funginite. ►Further evidence for multiple pathways of inertinite formation
