Summary: | Cloacaspis ceryx ceryx (Fortey, 1974) Figure 4D–F Balnibarbi ceryx ceryx Fortey, 1974: 28, pl. 8, fig. 1-6, pl. 9, figs. 1, 3, 4. HOLOTYPE: Cranidium, SMA 84034 (figured in Fortey, 1974: pl. 8, fig. 1). TYPE LOCALITY: Profilstranda, Olenidsletta Member, Valhallfonna Formation, Ny Friesland, Spitsbergen, Svalbard. STRATIGRAPHIC RANGE: Lower V 1b trilobite zone (Fortey, 1980), which coincides with the lower Oepikodus evae conodont zone and Pendograptus fruticosus zone within the upper Floian (fig. 1; see also Kröger et al., 2017). DIAGNOSIS: Cloacaspis ceryx species with relatively long (sag.) preglabellar field (0.08 – 0.19 length of glabella) and finely granular exoskeletal surface. Published as part of Hopkins, Melanie J., 2019, Phylogenetic analysis and revision of the trilobite subfamily Balnibarbiinae (Olenidae), pp. 1 in American Museum Novitates 2019 (3928) on page 1, DOI:10.1206/3928.1, http://zenodo.org/record/5369854 |
