Taxonomic remark Ichnogenus (fossil coprolite [or cololite]). From Knaust, 2020: Potential producer(s). Although some molluscs (e.g. species in Pectinidae) produce ‘filamentous cylindric rods loosely entangled and gathered by mucus to form masses of indefinite shapes’ (Arakawa 1965), the Lower Ordovician Anfractuosocoprolithus aphelus aggregates consisting of tightly folded faecal strings with very narrow bends (see Bischoff 1994, pl. 1, figs 1–5) are probably better explained as cololites instead of coprolites.
