Elemental composition of macerated fossils from energy dispersive X-ray microanalysis. (a) Point-analysis on a tube of Cyathinema digermulense gen. et sp. nov. shows that the fossil is primarily composed of carbon. TSGf18420a. (b,c) Elemental mapping shows the two most abundant elements. The fossils are composed of carbonaceous matter, and often covered with debris of titanium, likely originating from rutile. (b) TSGf18424. (c) Specimen of a rolled-up sheet, TSGf18420b.
