DescriptionAusichicrinites zelenskyyi gen. et sp. nov.jpg
English: Figure 4. Ausichicrinites zelenskyyi gen. et sp. nov. from the upper part of the Antalo Limestone Formation (38°22'49.1″ E; 9°28'41.8″ N; 2114 m elevation), 21 m above the upper Tithonian calcareous nannofossil-yielding sample 2043b, Ethiopia (see also figure 2 for its stratigraphic position). Scale bar equals 10 mm (a,c,e,f,g) and 1 mm (b,d,h,i). (a,c). Specimen with centrodorsal, arms and cirri ((a) non-whitened, (c) whitened) with magnifications (b,d) of IBr2 articulation (note a ‘dotted’ suture line (red arrows) from the outer surface of the articulation (b) and a fine ridge (red arrows) on the partly exposed facet (d)). (e) Lateral view showing a centrodorsal (non-whitened). (f,g) Tomographic images of slices of the fossil comatulids showing cryptosyzygial articulation at IBr2 (red arrows). (h) Proximal pluricirral (lateral view) and isolated cirri (facet view, blue arrow). (i) Regenerating pinnules consisting of one to three pinnular plates (blue arrows).
